Pirates' Arquimedes Caminero: Better since DL stint

Caminero struck out four batters in two scoreless innings Friday against the A's.

Since returning from the DL on June 11, Caminero has posted a 1.42 ERA with an 11:6 K:BB in 12.2 innings. He's still slotted as a middle reliever, but the improvement he's shown has likely saved his spot in the bullpen.
