The Tigers made two significant moves at the deadline, and they were arguably on the losing side of both of them.
Jose Veras is not the solution to their bullpen problems. He was an above-average pitcher over the past four months with the Astros, but he had been a significantly below-average pitcher over the previous four seasons.
Among the 42 relief pitchers who logged at least 230 innings from 2009-2012, Veras' WAR and FIP both ranked 38th.
Thanks to the small sample sizes, sometimes relievers are able to change their stripes for an extended period of time—just look at Fernando Rodney's numbers from 2012. But Rodney's 2013 numbers would indicate that mediocre relievers will eventually revert to the reputation they established over their first few seasons in the majors.
In the other trade, the Tigers gave up a strong prospect in Avisail Garcia for a Band-Aid at shortstop.
If Jhonny Peralta is going to be suspended for 50 games, the trade at least makes sense. And with Miguel Cabrera still dealing with a hip/abdomen issue, they're killing two birds with one stone by getting a guy who can play both shortstop and third base.
Jose Iglesias' glove has been mentioned in the same breath as Omar Vizquel's, but his bat is somewhere in the vicinity of Paul Janish and Alexi Casilla in the hierarchy of non-power-hitting middle infielders.
He rode an incredible BABIP from dribblers and bloopers to a .400 average over his first 30 or so games in the majors, but he's batting just .205 in the month of July.
Provided Peralta's looming suspension was the reason for the trade, the Tigers are effectively losing an All-Star-caliber shortstop, two prospects and a player to be named later. All they got in return was one of the least valuable relievers over the past four seasons and a light-hitting, great-fielding shortstop.
Ask yourself this: If they had traded Peralta and those two prospects to the Mariners for Brendan Ryan and Charlie Furbush, would they have been winners or losers?
