Let’s Improve Bryce Harper’s Defense

Bryce Harper began out as a catcher. By the point he was sufficiently old to drive, although, everybody knew his catching days had been numbered. When the Nationals drafted him in 2010, they stamped that nonsense out, as a result of nobody who can mash like Bryce Harper is allowed to waste their power and their knees behind the dish. Harper moved to the outfield, and people of us who had been there in 2012 will recall that for a short time, he was implausible on the market. He performed together with his hair on hearth, he had a rifle arm that slotted in properly alongside Rick Ankiel’s cannon, and in these first couple years earlier than Statcast appeared, he was downright quick. It didn’t final too lengthy, although. Harper determined to beef up, arriving in Florida every spring with increasingly more muscle mass and fewer and fewer footspeed. Additionally, he bumped into partitions rather a lot. For many of his profession, Harper was a poor outfielder, after which in 2023, he returned from Tommy John surgical procedure as a primary baseman, initially on a brief foundation. He has not performed within the outfield since.

Thus far this season, in line with Statcast’s Fielding Runs Worth, Harper has been the fourth-worst fielder in baseball. He’s at -7 FRV, forward of solely Willy Adames and Logan O’Hoppe at -10, and Owen Caissie at -8. In response to our defensive numbers, which embrace a positional adjustment, Harper has been value -12.3 runs, making him the worst defender in baseball by a considerable margin. In order that’s dangerous. No one desires to be on the very backside of the leaderboard. I imply, I suppose when you kind the leaderboard the wrong way up, it shouldn’t be referred to as a leaderboard anymore. It ought to actually be referred to as a trailerboard. Or perhaps the disgrace listing. I’m spitballing right here. The purpose is that’s not the place Harper desires to be. And it will get worse.

Statcast has FRV values relationship again to 2016. Right here’s the single-season trailerboard for that whole 11-year interval:

So the worst complete ever recorded is -9 FRV. Harper is already at -7, and he’s nonetheless bought half a season left to maneuver past 1,250th place. He’s on tempo for -13 FRV and -23.2 defensive runs, which might completely boat race the worst defensive seasons of the Statcast period. On the brilliant aspect, he’s now not working into partitions.

So is Harper one of many worst defensive first basemen in current historical past? The opposite defensive metrics don’t suppose so. (As a matter of truth, they’re formulation, in order that they don’t suppose in any respect, however you get the purpose.) Harper is at -1 Defensive Runs Saved this season, an enchancment over the -3 he put up in 2025. Deserved Runs Prevented, the flagship defensive metric of Baseball Prospectus, is way more conservative than the others, so Harper’s -0.3 mark makes him the fourth-worst first baseman this season. That’s very dangerous, however it’s not historic or something. Final season, he was at a optimistic 0.3 DRP. In different phrases, we’re seeing a sudden drop-off in line with two metrics, whereas the opposite metric thinks Harper has gotten very barely higher.

Harper additionally graded out fantastically at first base as just lately as 2024. That was his first full season on the place, and he nailed it. He was value 5 DRS, 5 FRV, 0.9 DRP. You possibly can take my phrase for it (together with the absence of minus indicators) that each one of these numbers are good. Two years in the past, Harper was an excellent first baseman and all of the computer systems thought so. This season, certainly one of them thinks he’s meh, one thinks he’s horrible, and one thinks he’s bordering on the worst ever to do it.

Now it’s time for the massive caveat you’ve been ready for. Defensive metrics are removed from excellent, and so they take a very long time to stabilize. In truth, once I began writing this text yesterday, Harper was at -8 FRV. Then final evening, he made a pair nice performs — certainly one of which you’ll be able to watch beneath — and knocked it all the way down to -7. That’s the factor about small pattern sizes.

Half a season of an unpleasant FRV doesn’t the worst defender ever make. Nonetheless, numbers this excessive positively imply one thing, and the good factor about Statcast is that it will get very particular. Right here’s why the flamboyant cameras dislike Harper:

First basemen don’t actually return on the ball an excessive amount of, so we are able to largely ignore that final column. Charging the ball isn’t Harper’s drawback both. Hit the ball proper at him, and he’ll most likely be simply high quality. The issue is on the perimeters. In 2024, Statcast says Harper was nice going each to his proper (towards second base) and to his left (towards first base). In 2025, he stopped being good to his proper aspect. This 12 months, he stopped being good to his left aspect, too. He has now formally run out of sides.

With this knowledge in hand, I hit the tape. Right here’s one other large caveat: Each participant goes to look dangerous for those who’re going into your movie session searching for the issues they’re doing fallacious. It’s simply human nature. Nonetheless, I did my finest to take a look at each single ball hit Harper’s means, not simply those that bought by him. Furthermore, I’m right here to assist. I did discover just a few clear points, and I’ve prescribed some easy fixes.

The primary drawback is that Harper isn’t nice at diving for the ball. That’s unlucky, as a result of though first base isn’t the new nook, the place remains to be awfully near house plate and entails a number of performs that don’t present a lot in the best way of response time. Harper has had a number of performs this 12 months the place he solely has time for a step and a dive. I believe {that a} fielder with higher instincts and a faster first step wouldn’t must dive fairly as typically, however there’s solely a lot I can do to quantify that. That’s what Statcast is especially good at, as a result of it is aware of each participant’s start line and the way a lot time they must make every play. For proper now, what I observed is that Harper not often appears to provide you with the ball when he dives for a grounder. On practically each play within the supercut beneath, he’s inside vary of the ball, however he doesn’t get his glove down in time, or he dives too late, or the ball deflects off him, or he simply doesn’t get prolonged.

All of those clips are simply from the primary half of this season, so that is taking place fairly frequently. I don’t actually understand how you repair that. Harper didn’t develop up enjoying the infield. He spent virtually no time on the grime till he turned 30. It would simply be too late for him to develop that specific talent, and it might be lunacy to danger an harm to such a worthwhile hitter by making him apply hurling himself to the bottom again and again. In order that half’s going to be powerful. Simply to make Phillies followers really feel higher about this one, right here’s a video of Harper making a diving play:

There, that’s good. Now, I don’t imply to say there’s nothing Harper can do to repair this drawback. I don’t understand how you get him higher particularly at making the play as soon as he’s diving for the ball, however I do suppose there are some things he might do to keep away from having to dive within the first place. I’m certain that engaged on his instincts and his first step is already part of his every day infield routine, however past that, there are a few methods for him to get ready to make just a few extra performs.

I’d argue that Harper ought to play a bit deeper to purchase himself extra time. This season, when lefties are on the plate with nobody on, the league’s first basemen have common depths ranging 120 ft and 130 ft. Harper is correct within the center at 125. When righties are up, he averages 111 ft, a bit shallower than common. In the event you recall the desk on the prime of this text, Harper has at all times been good, perhaps even nice, at coming in on the ball, so why not push him again only a couple ft? He nonetheless wouldn’t be the deepest first baseman on the market, however he would get slightly bit extra of the response time that he wants.

The subsequent subject I observed additionally has a reasonably easy repair. As I watched ball after ball sneak previous a diving Harper, I observed one thing easy. When he’s holding a runner on first base, he tends to not get again into an excellent fielding place. If you’re holding the runner on first, you’re all the best way on the sting of the sector, which drastically reduces your vary, since the entire space to your left is foul territory. As soon as the pitcher commits to house, first basemen often shuffle towards their proper with a view to get again right into a extra helpful fielding place. Harper is just not nice at that. In truth, he generally appears to neglect to do it altogether.

In response to the Statcast knowledge, Harper truly grades out in the midst of the pack when it comes to positioning when there’s a runner on first. His common angle is 41 levels, and a few gamers are as excessive as 43 (standing instantly on the foul line could be a forty five diploma angle). Nonetheless, that knowledge will get measured when the pitcher releases the ball, not when it crosses the plate, and at that time, most first basemen would solely be a step or two into their shuffle. Harper typically doesn’t appear to shuffle in any respect, and ball after ball leaks by his proper aspect, even balls which can be inside the cutout of the infield grass. Consider me once I inform you that the video above might have been longer. At a sure level, I finished pulling movies, as a result of there have been simply too many, so right here’s a pattern of screenshots that present simply how shut he’s to the bag:

He’s flat-footed in all of those pictures. No marvel the numbers say that he doesn’t have good vary going to his proper. He’s beginning as far to the left because it’s attainable to get, and he doesn’t appear notably considering correcting that. Once more, the Statcast numbers say that Harper is just not essentially the most egregious offender on this explicit rely, however he’s a participant whose vary might actually use some assist, and ensuring he remembers to take a shuffle or two with a view to get into a greater place looks like it might be fairly simple.

The final subject I observed particularly about balls to Harper’s proper is that he tends to get grasping. You possibly can’t run into that many partitions as a primary baseman, however you possibly can go steal grounders away out of your second baseman. I really like that Harper is aggressive. You need your first baseman to go get the ball. And generally, like on these performs, it really works out simply high quality.

These ended up as outs. That’s nice. However all of us noticed the second baseman behind Harper, able to discipline the ball, proper? Typically it doesn’t work out that nice.

The excellent news is that this ought to be no less than considerably fixable. I’m certain each infield coach has a drill the place they hit tweeners towards their first basemen with a view to assist them apply making the split-second resolution to go after the ball or cowl the bag. Let’s make {that a} common a part of Harper’s pregame warmups.

I’ve one final criticism. I believe Harper is genuinely nice at beginning the 3-6-1 double play and the 3-6 double play the place the primary baseman steps on the bag and the shortstop tags the lead runner. His turns are easy and his throws are robust and correct. That’s why Statcast thinks he’s nice coming in on the ball. These are sometimes balls the place he has to cost and make an excellent throw, and he’s wonderful at it. Nonetheless, I believe Harper doesn’t cost the ball exhausting sufficient, particularly on routine performs. He’s typically pleased to attend again even on softly hit balls, which signifies that he received’t have time to step on first base himself, which suggests his pitcher has to cowl and catch a flip. Now, Harper’s good at making that flip, however you’d nonetheless a lot fairly have your first baseman make that play himself. A variety of issues can go fallacious on these flips performs: errors, sprained ankles, collisions. Right here’s a evident instance:

This ball was a straightforward grounder hit at 49 mph, however Harper nonetheless selected to attend again and discipline it 15 ft behind the bag. Even then, he nonetheless had loads of time to make the play himself. The runner wasn’t even midway to first when he flipped the ball to the pitcher. This was a low stakes play, and about as simple a flip play as you’ll see, however it was additionally a play that didn’t necessitate a flip in any respect. Harper simply determined early on that he was going to flip it; that’s why he didn’t cost the ball, and that’s why he didn’t hold it even after the runner gave up on the play. Right here’s the next stakes instance:

It is a very simple play that Harper became a tough one. That’s Cy Younger candidate Cristopher Sánchez on the mound. The Phillies ought to be defending his ankles in any respect prices! Not solely was Harper the closest participant to first base when he fielded this ball, but additionally, take a look at the place everyone else was when he fielded it.

The batter is barely out of the field. Sánchez remains to be on the mound, and he has to bust it over to first. Watch that clip once more and look how exhausting he hits the bag. That is egregious. It hasn’t actually come again to chunk Harper simply but, however turning simple performs into exhausting ones is just not an incredible behavior.

In order that’s my critique of Harper’s first base protection. Only a fast 2,400 phrases. I ought to as soon as once more shut by noting that we’re speaking about small pattern sizes, and that Harper might be not fairly as dangerous as Statcast makes him out to be, if for no different motive than the truth that no first baseman has ever graded out as badly for a complete season as he has within the first half of this one. Nonetheless, I have to carry up another factor.

Just some days in the past, Tom Tango wrote a weblog publish revealing that Statcast will quickly be incorporating knowledge about how first basemen deal with throws. It’s an thrilling growth, and I like to recommend studying the entire publish, however we’re considering one particular half. Naturally, Tango talked about a pair gamers who stand out: “For the 2021-present (through June 27, 2026), Matt Olson and Freddie Freeman are tied at +25 receiving outs above common. Yuli Gurriel is at +12 at half the enjoying time. On the flip aspect is Bryce Harper at -13.” Harper is the worst at this stat despite the fact that he’s solely been enjoying first base since late 2023. As Tango was fast to say, Harper is a transformed first baseman. As a result of we don’t have a year-by-year breakdown, it’s completely attainable that he’s high quality at this explicit talent now, and that he racked up all that unfavourable worth when he was a beginner on the place. I requested a pair good Phillies followers (although I left Michael Baumann alone as a result of he’s on trip) what they considered Harper’s receiving. One stated they hadn’t observed it a lot a technique or one other, and one stated they thought he’s fairly good at it. So perhaps that is merely outdated information or nothing in any respect. Or perhaps Statcast is about to hate Bryce Harper much more.
