Cardinals put faith in defensive numbers in signing Jhonny Peralta

42 Comments

Jhonny Peralta should be a terrible defensive shortstop.

Defensive ability peaks significantly younger than offensive ability, and Peralta wasn’t really any good defensively in what should have been his prime. As a 24-year-old in 2006, he was the game’s second worst shortstop by UZR. In 2007, he was the fifth worst.

By 2008, Peralta graded out better, playing pretty much average defense according to UZR, but the Indians moved him to third base the next year, making room for Asdrubal Cabrera at short. In 2010, the Tigers acquired him and moved him back to short, where he was again average initially. And then a funny thing happened. Here are Peralta’s career UZRs in the seasons in which he played 500 innings shortstop:

2003: 2.5
2005: -6.1
2006: -10.6
2007: -12.4
2008: -1.0
2011: 10.3
2012: 11.5
2013: 3.5

In both 2011 and 2012, Peralta rated as the game’s third best shortstop. In 2013, he was 14th.

It’s a pretty amazing turnaround made more complicated by the fact that we know Peralta was at least dabbling in PEDs for a portion of it. The narrative for baseball is that steroids=home runs, even though it’s never made much sense to look at it that way. Sprinters, cyclists and the rest didn’t take to doping to build up their biceps.

We know Peralta isn’t a particularly fast guy. He has 13 career steals in 11 seasons, getting caught 21 times. However, his range ratings have gone from horrible in his mid-20s to above average these last three years. The rest of his game has always been solid: even during his days as a bad shortstop, he was above average when it came to avoiding errors and average at turning the double play. His arm is a strength.

As for the range, well, that can largely come down to positioning. Cal Ripken Jr. wasn’t fast either. Troy Tulowitzki isn’t speedy. Adam Everett and Brendan Ryan, two of the game’s very best shortstops over the last decade, weren’t/aren’t factors on the basepaths.

Peralta has obviously gotten much better at learning where to play hitters through the years. To my eyes, he still looks for all the world to be a below average defensive shortstop. But after three years of UZR saying the opposite, I have more faith in the numbers than in my eyes.

I’m still not a fan of the Cardinals’ reported move to give him $52 million for four years. He’s a cheater, and if nothing else, it adds greater uncertainty to what we can expect from him going forward. Offensively, he was great in his 107 games when he wasn’t serving his steroid ban last year, hitting a career high .303 with a .358 OBP and a .457 slugging percentage. However, it took a ridiculous .374 BABIP to produce that .303 average; he actually had his highest strikeout rate since 2007. His career BABIP is .315, and he figures to come in much closer to there next year, which could result in a .260-.270 average. He’s far from a consistent force:

2009: .254/.316/.375 – .691 OPS
2010: .249/.311/.392 – .703 OPS
2011: .299/.345/.478 – .823 OPS
2012: .239/.305/.384 – .699 OPS
2013: .303/.358/.457 – .815 OPS

Of course, just getting average offense and average defense from shortstop would be a huge upgrade over what the Cardinals have received of late. I wouldn’t expect much more and I wouldn’t want to be on the hook for the back half of that contract, but for 2014, he makes the NL’s best team considerably better.

Kris Bryant exits game with sprained right ankle

The Cubs had a scare on Wednesday night when third baseman Kris Bryant left with an apparent ankle injury. In the bottom of the fifth inning, Nationals catcher Matt Wieters hit a pop up that veered just into foul territory near the third base bag. Bryant caught it but his momentum took him back into fair territory. In doing so, he stepped awkwardly on the third base bag and appeared to twist his ankle. Bryant needed the assistance of manager Joe Maddon and the team trainer to get off the field.

Bryant was diagnosed with a mild ankle sprain, CSN Chicago’s Patrick Mooney reports.

Bryant was 2-for-3 on the night before departing and being replaced by Jeimer Candelario. He’s now hitting .264/.395/.520 with 16 home runs and 32 RBI in 329 plate appearances. Needless to say, the 39-39 Cubs would see their playoff odds hurt immensely if Bryant were to miss a significant amount of time.

Hector Gomez reports Twins third baseman Miguel Sano will participate in the 2017 Home Run Derby, to be held in two weeks at Marlins Park in Miami. So far, Marlins outfielder Giancarlo Stanton is the only other confirmed participant.

Sano, 24, is having an outstanding season, batting .274/.375/.548 with 18 home runs and 53 RBI in 293 plate appearances. According to MLB’s Statcast, only Yankees outfielder Aaron Judge (96.7 MPH) has a higher average exit velocity than Sano (96.4 MPH).

Brian Dozier was the last member of the Twins to participate in the Home Run Derby. In 2014 at Target Field, Dozier failed to make it into the second round after hitting only two home runs. Justin Morneau is the only Twin to have ever won the Home Run Derby, as he beat Josh Hamilton 5-3 in the finals of the 2008 Derby at Yankee Stadium — although Hamilton out-homered him in total 35 to 22.
