Keller was recalled from Triple-A Indianapolis on Saturday.

EDGE Analysis

Keller spent over a month with the Triple-A club, and he posted a 2.20 ERA, 0.86 WHIP and 26:1 K:BB in 16.1 innings during his most recent stint in the minors. The right-hander has made three major-league appearances this year and should serve mainly as a low-leverage reliever going forward.
