Matt Lindstrom has allowed an earned run in three of his last five relief appearances.
The streaky Idahoan didn't allow a run through April 20, then gave up six in his next four appearances, then was perfect in May until the 10th, when his newest batch of concerns cropped up. The 32-year-old reliever, signed to a one-year, $2.8 million contract over the winter, holds a 4.76 ERA over 17 innings. Lindstrom will continue operating out of a middle relief role.
Born and bred in Minnesota, Neshek has been a decent middle reliever since he was unceremoniously waived by the Twins prior to the 2011 season. Over the last two seasons in Oakland, he's posted a 2.02 ERA, 1.15 WHIP and 27/14 K/BB ratio over 42 appearances.
Jonathan Herrera is batting .283/.327/.370 through 49 plate appearances.
If his slash numbers hold, Herrera will finish with the best offensive season of his career, topping the .694 OPS he mustered in 2010. Unfortunately, the utility infielder has scuffled in the field recently, recording three errors in his last 12 games.
