Let’s See What Greg Bird Could Be
The masses are encouraged by Bryce Harper’s spring. Everyone’s looking for a big bounceback season, so it seems like a good thing that Harper is second in spring-training home runs, with six. Well, Greg Bird is looking for a bounceback season of his own — not because he was bad in 2016, but because he wasn’t anything in 2016. Surgery’ll do that to a player. After Wednesday, Bird is right there with Harper, at six home runs. Let’s just continue to try to ignore that Peter O’Brien is ahead of both of them, with seven.
Out of sight usually means out of mind, as fandom goes, and Bird, for a while, was sort of a forgotten young Yankee, what with the group emergence of Gary Sanchez, Aaron Judge, Tyler Austin, and so on. It’s nothing Bird could help, but labrum surgery kept him from playing, and it was all he could ask for to have a successful spring. Suffice to say Bird is back in the picture. Suffice to say he’s generating at least as much enthusiasm as anybody else. Through 47 exhibition trips to the plate, Bird’s hitting .439, with a four-digit slugging percentage. He’s been the very best spring-training hitter, and while that’s not something anyone actually cares about, there is significance here. It would sure seem that Bird’s shoulder is fine.
There are risks that come with hitters needing shoulder surgery. I mean, there are also risks with wrist surgery, or hand surgery, but think about how Michael Brantley is still mostly an unknown in Cleveland. When Bird last played with the Yankees, he was able to do things like this:
Wednesday, against the Phillies, he did this:
I don’t have spring-training exit velocities, but in these cases I don’t really need them. A home run is a home run, and Bird has six of them already. It’s why Harper’s spring seems like such a positive — if he was hurt last season, he appears healthy again. Bird, too, appears healthy, allowing the Yankees a sigh of relief. They can assume that Bird is back on course, and when they last saw him, he was a sensation.
He wasn’t quite a Sanchez-level sensation, because those come around once every couple decades or so, but Bird slugged .529, with the talent to back it up. He also struck out a bunch, but considering it was Bird’s first-ever exposure to the major leagues, he more than handled himself. And, Bird debuted and got all his action in in 2015, before we were all so comfortable using Statcast information. Now it’s practically a requirement. As such, I want to repeat a little experiment I recently ran on the subject of Justin Smoak. The idea: I have corrected exit velocities, I have launch angles, and I have contact rates. I have what Bird did in his time with New York as a rookie. What hitters from the last two seasons have looked most similar? This table includes all the strongest, closest comparisons:
| Hitter | EV | LA | Contact% | Comp Score | wRC+ |
|---|---|---|---|---|---|
| Gregory Bird | 88.5 | 18.6 | 75% | — | 137 |
| Lucas Duda | 88.2 | 17.6 | 77% | 0.7 | 122 |
| David Wright | 87.2 | 17.4 | 74% | 1.0 | 125 |
| Freddie Freeman | 89.1 | 15.9 | 74% | 1.1 | 144 |
| Brandon Belt | 86.0 | 18.3 | 75% | 1.2 | 136 |
| Trevor Story | 88.0 | 16.2 | 73% | 1.3 | 120 |
| Nick Castellanos | 87.6 | 17.0 | 72% | 1.3 | 105 |
| Kyle Schwarber | 88.4 | 18.0 | 67% | 1.5 | 129 |
| Matt Carpenter | 87.9 | 17.7 | 81% | 1.6 | 137 |
| J.D. Martinez | 89.3 | 15.4 | 72% | 1.7 | 139 |
| Adam Duvall | 85.4 | 17.6 | 74% | 1.7 | 105 |
| Justin Smoak | 88.6 | 13.8 | 73% | 1.7 | 99 |
| Randal Grichuk | 87.5 | 16.1 | 71% | 1.8 | 117 |
| Mark Trumbo | 89.1 | 14.6 | 72% | 1.8 | 116 |
| Tommy Joseph | 86.5 | 16.6 | 78% | 1.9 | 113 |
| Andrew McCutchen | 87.0 | 14.5 | 76% | 1.9 | 126 |
| Kris Bryant | 86.8 | 19.5 | 70% | 1.9 | 143 |
| Justin Upton | 87.8 | 15.4 | 71% | 1.9 | 112 |
| Mikie Mahtook | 85.6 | 17.0 | 74% | 1.9 | 87 |
| Evan Longoria | 86.4 | 15.5 | 77% | 2.0 | 116 |
| Todd Frazier | 84.6 | 17.3 | 75% | 2.0 | 109 |
I want to emphasize this doesn’t prove anything. When I did this for Smoak, I was surprised by the results, and so were plenty of readers. Maybe I’m missing too much in this analysis. But just based on what Bird has done in his limited time, he’s swung the bat an awful lot like Lucas Duda. The top five comps are rounded out by David Wright, Freddie Freeman, Brandon Belt, and Trevor Story. The average wRC+ in the whole table is 121, which is lower than what Bird did, but he doesn’t appear like an outlier. If anyone is an outlier, it’s Mahtook.
Bird generated some strong, positive exit velocities. His contact rate was low, but still in the normal range. Where Bird is most extreme is in his fly-ball tendency, but that was nothing new. Between levels in 2015, his grounder rate was 30%. The year before, it was 31%. The year before that, it was 33%. Bird has a fly-ball swing, and fly balls have always come off of it. He’s perfectly built for his home stadium, and there’s still room to improve.
From the sounds of things, Bird’s shoulder was bothering him even when he was clobbering the ball as a rookie. If he’s now consistently able to swing freely, in the way that he wants, it makes sense his exit velocities could be better. His contact rate could be better, too, which we’d already expect just on account of maturity and experience. Bird, in his time, swung at a lower rate of pitches out of the zone than the average. He demonstrated fairly advanced judgment. The biggest obstacle now might simply be improving against same-handed pitchers.
I know people have pointed out that Bird’s rookie hot streak was out of step with his minor-league power numbers. It’s a fair point, but an incomplete one. For one thing, Bird didn’t fake his batted-ball speeds, which ranked among the better marks in the league. And then, while Yankee Stadium is obviously lefty-friendly, Bird’s minor-league environments were very much not. Charleston? Nope. Tampa? Nope. Trenton? Nope. Scranton/Wilkes-Barre? Nope. Bird, in the minors, would’ve had his power at least partially suppressed, and he’s still managed a minor-league OPS of .878 from the ages of 18 to 22. Yankee Stadium will probably grant Bird a few freebies, but his power is bigger than previously advertised.
It’s being more sensibly advertised now. Greg Bird is healthy again, and he’s back in the picture as a young Yankee regular. If he doesn’t get much better at all, he’s something like a younger Lucas Duda. And with a step forward somewhere, he becomes a franchise cornerstone. Not everyone is cut out to be an extreme fly-ball hitter. The profile fits Bird like a glove.
Jeff made Lookout Landing a thing, but he does not still write there about the Mariners. He does write here, sometimes about the Mariners, but usually not.
Good article. I also liked the one from a couple weeks ago in the community research area:
http://www.fangraphs.com/community/greg-bird-what-can-we-actually-expect/
Very interesting, thanks for the article. I knew the Yankees’ minor league parks were pitcher friendly, but I didn’t fully realize the extent to which they suppressed LH power (especially Tampa and Scranton).
IIRC, it was the worst hitter’s park in the EL at one point (~6-7 years ago) and it’s one of the reasons why scouts salivated over a 19-year-old Jesus Montero.
I can’t tell you the number of times I’ve seen dudes hit absolute rockets to right/right-center at SWB and they just… kind of… die. The stadium is pretty much cut into a mountain, and behind right field is pretty much a man-made cliff face. I don’t know exactly how that affects things, but it fits well, psychologically, with the image of batted balls hitting a wall out there.
I love Greg Bird and think if he’s healthy he’s going to be a star, a guy who makes all-star games. He has raked everywhere, including his stint a couple years ago in NY.
That’s always been the line on Bird – he just flat out hits. And boy is it ever true. I don’t know if there was any kind of consensus that he’d be a true 1B HR-power guy as opposed to a gap-power guy, but it’s looking like he’s gonna have a shot to plant himself firmly in that first group.
Also, apropos of nothing, everyone should look up a picture of the Greg Bird Bobblehead that SWB gave away. It’s… different.
You mean the hatchling one, or the SI Yankees’ riding an engle one?
Ha I meant the hatching one; I didn’t know about the other one. Clearly the no-fun organization is trying to have a bit of fun with this fellow.
That being said, once he’s an established big-leaguer, they’ll probably have a bobble-head of Greg Bird shaving his 5 o’clock shadow so as not to incur the wrath of management
I don’t think I really grasped how good Bird could be until I read Kiley McDaniel’s writeup of the Yankees prospects…
“One way that scouts pick up on this is that Bird will not show you all of his raw power in BP. I’ve seen Bird take BP at least a half dozen times and, while Judge will let it loose in the last round and Gary Sanchez tries to put a hole in the outfield wall in most of his BP swings, Bird will just hit line drives all over the field with every swing. I’ve seen him hit homers in games to all parts of the ballpark and seen him carry the center field wall by 30 feet. It’s plus power and it might be a 65, I just haven’t seen it in BP to confirm.”
…and then I realized that anyone with that hit tool and that power was going to be a beast. He seemed like the safest prospect I had seen in a long time, and with a huge ceiling too.
Since this is like the third or fourth time you’ve used this “Comp Score” method, I wish it was just a little clearer how you calculated it.
I understand it’s “based on z-scores” and z-scores aren’t all that complicated, but if you’re going to use this method so often, I just think you should spell out exactly what it is.
Not doubting your work, or it’s accuracy, just want to understand it better.
I understand your point and it’s a valid one. It’s just a balance between thoroughness and readability. All I do is calculate z-scores for each statistic, taking the absolute value of the result. Then I add up the three z-scores. That’s what the comp score is, here.
Jeff,
You could have a little page explaining the process for those who care and have a link to in the pages that reference the process. Then the Ted Nugents of the world will be satisfied. (Insert Ted Nugent joke here).
Those z-scores compare Greg Bird and everyone else to the average, right? But these comp scores compare everyone to Bird, specifically.
After adding the three z-scores, are you just seeing which players’ sums are closest to Bird? Because we’re comparing everyone to him, and z-scores relate to the average, of course.
Jeff, I liked that we came up with some similar comps from the data coming at it from different angles. Now I just wished I had invested in him in my main league.
Albeit a “best-case” comp, but from everything I’ve read, Bird seems to fit somewhere between Votto and Freeman — a plus natural hitter, without the aggression in his swing to hit for 30+ HRs, but the type to always give quality ABs and get on base a .380 clip. Like Votto & Freeman, I think he could walk into a season with 30+ HRs at some point, but don’t think that’s his game really.
I think his big hurdles this season will be hitting LHPs and surviving versus the shift, give his pull-happy ways.
The flies will help with the shift, haha.
Bird has raked at every level, while being young or on target for the league. I think that one reason he gets overlooked is that, at the plate, his swing is smooth without being physically impressive. He looks almost gangly. The best comp I can think of is John Olerud.
I think Bird is going to produce at a star level, at least for a couple years, but will have to overcome this visual bias of not “looking” like a star.
One of the other encouraging signs is that Bird is also running a K rate of 18% this spring which is more in line with what he did in the minors, as opposed to the 30% he put up in MLB in 2015.
