Nicolas has been at Triple-A Louisville since late April, but he'll now also lose his place on the 40-man roster in order to make room for Lyon Richardson, who was selected to the active roster Saturday. Nicolas gave up seven earned runs in just 7.1 innings during his time with the big club and hasn't performed much better in the minors, accumulating a 5.17 ERA and 2.24 WHIP in 15.2 frames.

Nicolas spent the past two weeks on the big-league roster and got into seven games, struggling to an 8.59 ERA, 2.86 WHIP and 7:13 K:BB over 7.1 innings. That damage was largely a result of two poor outings during which he yielded a combined seven runs across 1.2 frames; in his other five appearances, he wasn't charged with any earned runs. Nonetheless, Nicolas' awful 31.0 percent walk rate is likely something he'll be tasked with working on while in the minors.
