Michel Otañez: Everything you need to know

The Rangers designated Otanez for assignment Saturday. Otanez has spent the entire season in the minors, and he'll now lose his place on the 40-man roster after posting a 6.15 ERA and 1.72 WHIP in 26.1 innings. Joe Ross was selected to the big-league roster in a corresponding move.

The Rangers optioned Otanez to Triple-A Round Rock on Monday. Otanez took himself out of contention for a spot in the Rangers' Opening Day bullpen after yielding four earned runs on four hits and one walk over 2.1 innings across his three Cactus League appearances. The 28-year-old righty will serve as a leverage arm at Round Rock to begin the season while he waits for an opening to re-emerge in the Texas bullpen.

The Rangers claimed Otanez off waivers from the Athletics on Wednesday. Otanez is a hard thrower with a 34.1 percent strikeout rate but also a 14 percent walk rate over 39.1 big-league innings. The 28-year-old will compete for a spot in the Rangers' bullpen.
