2016 has been a lost year for outfielder David Peralta. Last season, Peralta busted out with a .312/.371/.522 slash that included 26 doubles, 10 triples, and 17 homers in 517 plate appearances. The team was hoping to build upon that performance to make a run in 2016 which hasn't happened due to various injuries and/or poor play across the board. Peralta has been on the DL three separate times this year, two times for his right wrist in what I think are unrelated injuries, but could be linked. In 2016, he hit .251/.295/.433 this season with 9 doubles, 5 triples, and 4 homers in 171 plate appearances before slamming his wrist against the fence making a game-saving catch Friday night against the Brewers.
The purpose of the surgery is to stabilize a tendon in his right wrist, which has been bothering him since Giants series in mid-April when his wrist was hit by a pitch on consecutive nights. It's not surprising the production drop occurred with the wrist injury and hopefully he is healthy in 2017. Peralta is unlikely to repeat his 2015 numbers due to a .368 BABIP, but it is not unrealistic to see him being a large part of things once healthy in 2017 since he still hasn't lost any overall bat speed. With the Diamondbacks sitting at a 47-66 record, there is no reason for Peralta to rush back from this injury and play on a bad wrist. Hopefully the recovery goes along well, although we are 6 months away from Spring Training so he has a lot of time to get well.
Moving on from here, the Diamondbacks have the freedom to place Peralta on the 60-Day DL since he is not returning this season. That may be the move when the Diamondbacks ultimately activate starting center fielder AJ Pollock from the 60-Day DL later this month. At the same time, it doesn't really change the outfield equation much since Peralta has been on the DL since Sunday. In the last two months of the season, we should see Brandon Drury and Yasmany Tomas play everyday on the corners, although Drury has the versatility to add depth at 3 of the 4 infield spots. I don't think this will affect Mitch Haniger's promotion one bit, unless Tomas' neck is in worse shape than we thought and requires a DL stint.
