In my previous post, I mentioned that the Twins’ had the tenth-ranked defense in the league (or a .700 Defensive Efficiency rating, the definition and formula for which can be found here) according to Baseball Prospectus and I guess I should elaborate on that. The Twins have committed the fewest errors in the AL, and have an AL-best .990 fielding percentage, but neither one of those stats really measures defensive efficiency. That is, they don’t measure how effectively a team converts balls in play into outs, at least not accurately. As I discussed in the Mauer post, in general I like to use Ultimate Zone Rating to evaluate player defense. However, because it essentially measures how many runs a particular player saves per game, the values sometimes fluctuate wildly from season to season, so it’s not the best metric for evaluating defense over the short-term. At least not on its own. To evaluate team defense during the season, I also like to use Defensive Efficiency and Park-Adjusted Defensive Efficiency
(which, like the name implies, adjusts for ballpark factors that might
effect the Defensive Efficiency Rating) to get a full picture of how well the Twins are converting balls in play into outs. And, at least this season, they haven’t been very good at it. The team UZR is a 19th-ranked -6.5, on top of the .700 Deff Eff and 12th-ranked 0.4 PADE, so it’s clear that Twins’ defense has been mediocre at best. Which wouldn’t matter so much if they had more strikeout pitchers on the staff, but with a rotation full of contact pitchers, the defense needs to be better than just average.
I guess there isn’t a better player than Delmon Young to illustrate my point. Young has only made two errors this season, and his fielding percentage is .967, so one would think that Young is a pretty good left-fielder. However, Young has a poor -6.7 UZR this season, and his career -23.1 UZR is about as bad as it gets. So while he might not make a lot of errors, he doesn’t have much range and isn’t very good at converting balls in play into outs. But you really don’t need any fancy metrics to come to that conclusion. Anyone who’s actually watched Delmon lumbering around in the outfield can tell that he isn’t very good. The numbers simply support that assessment.
- Frankie finally has another quality start
Well, technically last night’s game against the Mariners was a quality start: one earned run on three hits over six innings but Frankie didn’t exactly pitch as well as that looks. He struck out six batters, but walked four and had to pitch himself out of a self-imposed jam nearly every every inning. He’s still struggling with his command, but at least he managed to not melt down when he got himself in trouble. He still needs to throw his changeup a little more, and needs to work on command of his fastball, but it’s certainly a step in the right direction. Of course, he had a similar performance at Yankee Stadium and then failed to make it past the fourth inning in his next three starts, so he’s going to need to string a few quality starts together to keep his spot in the rotation.
Fangraphs’ Dave Cameron has an interesting solution to the Delmon Young problem. Young wasn’t off to a great start before his mom died, but he’s been awful since returning to the team and just seems lost at the plate. The Twins can’t just send him down, since he’s out of options and almost certainly wouldn’t clear waivers even as bad as he’s been. It might be best for both sides to go the D-Train route: Young would have a chance to get himself together without the pressure of fighting for a playoff spot and the Twins would get to compete for the division title with their best outfielders.
What’s wrong with the South Side? Paul Konerko does his best to explain why nobody seems to want to come play for the Fightin’ Ozzies.
Justin Morneau finally made good on his bet with Strib beat writer LaVelle E. Neal, III. I guess he didn’t do too badly on his first-ever blog post, even if it is a little short (not everyone needs to write 25,000 word essays like I do). But don’t quit your day job, Justin.
