We're told that Fizzleman wants to find more playing time for Anderson Hernandez, so he's going to try him out in left field.
What to say about this? Right now, we have probably the second best position player in the organization, Elijah Dukes, toiling in AAA because there isn't playing time for him in DC. And on Sunday, Hernia's debut in left, Riggleman had Willie Harris at second.
The net loss of value in playing Hernandez in left and Harris at second is hard to underestimate. Harris is one of the better defensive left fielders in baseball. His career UZR/150 is 18.9, meaning he's nearly 19 runs better than the average LF over the course of a full season. Meanwhile, he's a -0.9 UZR/150 second baseman. Over the course of a full season, that 19.8 run differential would be worth almost 2 full games.
Hernandez is a +8.9 UZR/150 second baseman. In left? Who knows. Let's be generous and say that despite his total lack of experience in the outfield--he's never played an inning in the outfield in the majors or minors ever--that's he's no worse in left than Adam Dunn, who's a -12.1 UZR/150 LF. Felipe Lopez was a -41.1 LF in his adventurous stint out there for the Scats last year, so I'm probably being overly generous. That's another 21 runs lost, another two games.
Of course, Fizzleman isn't going to play Hernia in left and Harris at second every day. I'm just projecting out the folly over time to show how bad the choice is. And right now, he's got Harris playing mostly in the infield, where his value is mostly nil, and to even consider compounding that by putting a second baseman in left is just nuts.
Do it once as an experiment during a blowout, fine. Let's hope it doesn't happen again.
