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.

Watch: Mike Trout ties MLB record with his 25th home run

It was only a matter of time before Mike Trout courted another all-time record, and on Saturday, he found himself in elite company with his 25th and 26th home runs of the season. He put the Angels on the board with a 429-foot blast in the first inning, depositing an 0-1 fastball from the Orioles’ Kevin Gausman into the left field bleachers:

In the third inning, with the Angels up 2-1, Trout returned to tack on another insurance run. He targeted Gausman’s slider for his second solo shot of the evening and cleared the center field fence with a 418-footer to bring his total to 26 home runs on the year.

Trout has mashed at a staggering .339/.471/.596 clip since his return from the disabled list last month, and Saturday’s totals helped mark his sixth consecutive season with at least 25 home runs. That’s a record few have matched before their age-26 season; in fact, only Hall of Fame sluggers Eddie Mathews and Frank Robinson have ever pulled it off.

Assuming he continues to rake in hits and plate appearances over the last six weeks of the regular season — and there’s nothing to indicate that he won’t — Trout is in line to join elite company of a different kind. The 26-year-old entered Saturday’s game with a 206 OPS+ (park-adjusted on-base plus slugging). According to MLB.com’s Matt Kelly, that means Trout’s hitting at a better clip than the average Major League player by a full 106 percent. Should he finish the year with a 200 OPS+ and 502 plate appearances or better, he’ll be the first player to do so since Barry Bonds obliterated the competition with his 263 OPS+ in 2004.

Blue Jays acquire Tom Koehler from Marlins

The Blue Jays acquired right-hander Tom Koehler from the Marlins in exchange for minor league right-hander Osman Gutierrez and cash considerations, the clubs announced Saturday. Koehler is in his sixth year with the Marlins and stands to make $5.75 million in 2017. He’ll be arbitration eligible in 2018 and is set to enter free agency by 2019.

The 31-year-old right-hander struggled to a 7.92 ERA, 4.7 BB/9 and 7.1 SO/9 over 55 2/3 innings with Miami in 2017. He was optioned to Triple-A New Orleans in late July, where he rebounded with a 1-1 record in seven starts and whittled his ERA down to a 1.67 mark. The Blue Jays have yet to establish Koehler’s role within their organization, but are hoping to see a turnaround from the righty when he breaks back into the big leagues.

Gutierrez, 22, was assigned to Single-A Greensboro on Saturday. He has yet to find his footing in the minors, and exited a 78-inning stint with Single-A Lansing after racking up a career-worst 7.85 ERA and 8.2 SO/9. His lack of control is particularly alarming, with a 6.2 BB/9 that dwarfs the 2.0+ BB/9 of seasons past, but he still has plenty of time to figure out his mechanics before reaching the Show.
