In his fourth season in the Rangers system, Evans broke out after moving to the bullpen full-time.

Back in Hartford for the third straight year, Pierpont was again terrific for the Yard Goats. The right-hander from Winthrop University saved 32 games in 34 chances in his first season as a closer -- twice as many as any other Top Reliever nominee -- while earning midseason and end-of-season Eastern League All-Star selections and posting the first sub-2.00 ERA of his career.

Like Frare, Poche was dealt midseason, going from the D-backs to the Rays in May. A D-backs Organization All-Star last year, he was as dominant a reliever as any in baseball. The southpaw fanned 15 batters per nine innings, striking out 23 in 11 innings with Double-A Jackson in the Arizona system, nine in five frames with Double-A Montgomery after the trade and a jaw-dropping 78 in 50 innings with Triple-A Durham.

In total, the righty fanned 89 batters in 68 innings and limited opponents to a .166 average on the way to his September big league debut.
