Buster Posey’s Terrible Second Half

Buster Posey was great as a rookie in 2010. He was fine in a 2011 that was largely truncated by his broken leg, then was outstanding in 2012 as the Giants won another World Series. He was almost certainly the first catcher off the board in just about fantasy draft this year, with perhaps a few holdouts for Joe Mauer making it less than unanimous, and they were rewarded with… well, it’s hard to be disappointed by .294 and 15 homers from your catcher. But it was merely a good season, and not a great one, wasn’t it?

That’s backed up by the fact that he finished seventh in catcher wOBA (min. 250 PA), behind guys like Jason Castro and Yan Gomes, and also seventh in Zach Sanders’ end of season rankings. Seventh isn’t bad, of course; it’s a starter in even the shallowest of leagues. But it’s also not what fantasy owners were expecting, and that means we need to understand why in order to figure out where he’s appropriate to draft headed into 2014.

Any review of Posey’s 2013 has to start with a simple breakdown of his first half and second half, because the differences were huge.


Before the break, Posey’s .400 wOBA was only slightly behind his 2012 career season; after, his offense was in the Eric Young / Zack Cozart range, which is an enormous problem, especially when you look at the shocking drop in extra-base hits from 41 to 9. (It should be noted that the “first half” is actually more than 50%, so “second half” will always be less, but still.)

So what happened? It’s not injury, so far as we know. He had a small fracture in his right ring finger in early September, but his troubles started far earlier than that. In late July, he said he was “pressing”; near the end of the year, Bruce Bochy said Posey was a “victim of high expectations”. Neither of these help us all that much.

One possibility, perhaps, is overuse. With Brandon Belt emerging to take the first base job, Posey spent most of his time behind the plate, starting 73 of the 94 games before the break at catcher, along with another 10 at first (and two at DH). Bochy said that was a goal in April, but it remains to be seen whether it was a wise one. Posey ended up catching the most games of his career, but at one point — in late June, just around when the slump began — he saw some time at first due to what was termed “general tightness in his legs“.

On that day, June 30, Posey homered in Colorado, his fourth longball in five days. His OPS stood at an excellent .940. But he’d go hitless in the next four games and would homer just twice in June, tumbling that OPS down to .889, and then he’d hit just one homer in August and September combined.

I’m not sure we can say with absolute certainty that all the catching killed Posey’s bat, but in the absence of any other reasons, and with all the history we have of catchers taking such punishment that they can’t keep up the pace at the plate, it certainly fits. He’s still young at 26, of course, but he’s also suffered a catastrophic leg injury.

Headed into 2014, Posey remains a top-10 catcher, an easy starter in all leagues. He’ll almost certainly be drafted as a top-3 catcher on his name alone, but unless we hear that the Giants have more solid plans to get him out from behind the plate more — which may be tough, since Belt was so productive in 2013 — there’s more than a little reason to tread lightly with him going forward.

    In my 14 team OBP league I took Santana (61st overall) behind Mauer (59th)and Posey (26th) and couldn’t have been happier. In AVG leagues I realize this isn’t helpful but if you can nab him at this spot in an OBP league he becomes an EXTREMELY valuable pick up. Especially when you consider he will get quite a few ABs as DH which theoretically should help him stay healthy.

    Overuse just doesn’t make sense. The guy is 26 years old. So what do the stats tell us? First half his OBP was .070 higher than his BA, second half it was .089 higher. So his eye was fine. In fact, he may have been consciously trying to take more walks. All the power numbers fell off a cliff, indicating he wasn’t able to drive the ball, and this shows in his BABIP as well. There’s an injury here we’re not aware of.

    So what type of injury curtails your ability do drive the ball but still allows you to play? Torso, groin, hip, maybe even a sports hernia. I wouldn’t rule out a fatigue-inducing illness either. I’m sure it’ll come out eventually.

      As Mike suggests, Posey had leg injuries that the Giants didn’t disclose to media. San Francisco is notorious for pressuring players to play through injury, and from what I’ve read it was applied to the entire 2013 team, with Scutaro and Crawford needlessly starting with destroyed fingers and errant swings.

      This is a huge pain for fantasy because we won’t get DL eligibility and worse, aren’t even aware the player is injured unless we follow San Francisco news. Posey’s injury probably stems from a July 21 game against the Diamondbacks where he was thrown at at home trying to score from first base on a double.

      I would urge caution drafting any San Francisco starter in 2014 who isn’t Hunter Pence or Madison Bumgarner, players without injury history. Even if they’re productive, if they get injured they can hurt you far more than someone on a normal team.

    I’m glad someone finally brought up Posey’s struggles. I acquired him in June and what came next was a couple months of major disappointment.
