The Marlins have seen enough of Brett Hayes, who has hit a meager .202/.229/.254 (.204 wOBA) in 118 PA. The most appalling stat about Hayes's season is his strikeout rate; in just 118 PA, Hayes has struck out a whopping 49 times, including twice today. Jose Reyes has been to the plate more than four times as often as Hayes and has only whiffed 44 times. Hayes's 41.5 percent strikeout rate is absurd; among Marlins in team history with at least 100 PA in a season, Hayes's strikeout rate is far and away the largest in team history. Giancarlo Stanton's rookie season with a 31.1 percent strikeout rate is second in that list.
To replace Hayes, the Marlins will bring up Rob Brantly, who will be the first player from the Detroit Tigers deal that dealt away Anibal Sanchez and Omar Infante to make their Marlins debut. This does not come as much of a surprise, as Brantly has been raking since arriving in Triple-A New Orleans. Since getting to New Orleans, he has hit .365/.389/.558 (.411 wOBA), albeit with a very fortuitous .415 BABIP. Still, put his Triple-A numbers together and Brantly has hit a respectable .286/.321/.363 in 193 PA at that level while also spending his first 197 PA hitting .311/.359/.461 (.362 wOBA) in Double-A.
Brantly should take a spot as John Buck's backup catcher, with a decent shot at getting more than the usual backup catcher's share of appearances given Buck's struggles and Brantly's left-handedness. Perhaps the Marlins will test out Brantly to see if he can be the team's catcher in the immediate future by spelling Buck more often against righties in addition to the usual afternoon off-days.
