Data doesn't support Bradley's claims of ump bias

Leave a comment

Last week Milton Bradley complained that his various run-ins with umpires have caused the men in blue to widen their strike zone when he’s at the plate:

Unfortunately, I just think it’s a lot of “Oh, you did this to my
colleague,” or “We’re going to get him any time we can. As soon as he
gets two strikes, we’re going to call whatever and see what he does.
Let’s try to ruin Milton Bradley.” It’s just unfortunate. But I’m going
to come out on top. I always do.

What am I supposed to do? You lead the American League in OPS, and
two years in the top three in the league in on-base percentage. All of
a sudden now, I come to Chicago and I can’t see the ball no more? I
don’t know a strike from a ball? I don’t think I’m doing anything
wrong. There’s a lot involved, and it’s a lot of politics where there’s
nothing you can do about it.

The beauty of being a baseball fan in 2009 is that smart people have
access to the data necessary to actually investigate those types of
claims. Dave Allen of Baseball Analysts did just that, breaking down MLB.com’s PitchF/X data to see whether Bradley’s strike zone has indeed expanded recently.

His lengthy analysis is definitely worth reading, if only for the
cool-looking charts of the strike zone, but the short version is that
“there is no statistical difference between Bradley’s zone this year
and his zone in 2007 and 2008.”

Mets starter Jon Niese left his start Tuesday night against the Cardinals due to left knee pain.

Niese walked two and gave up an RBI single before leaving with a trainer with one out in the bottom of the first inning. He was eventually charged with three earned runs. Robert Gsellman, just up from Las Vegas, took over, making his major league debut under unexpected circumstances.

Niese, who has not pitched well at all since coming over in a trade with the Pirates, is likely to be placed on the disabled list after the game or before tomorrow’s game.

Mark Trumbo’s home run streak ends

Mark Trumbo still has many chances to hit a home run tonight — it’s only been an inning or so in the Nats-Orioles game — but his weird home run streak is over.

Coming into tonight’s game, Trumbo’s last seven hits had been homers. The all-time record had been 11, set by Mark McGwire back in 2001. The last time Trumbo got a hit that wasn’t a dong was back on August 11. Later in that game, however, he hit a grand slam. After that he went 6 for his next 34, with all those safeties dingers.

But that’s over now. In the first inning tonight he drove in a run with a two-out single. Then he was thrown out trying to stretch it to two. Good job on the RBIs, Mark. Bad job on the base running. Judgment withheld on the homer streak because, really, that’s just kind of weird and cool.
