Mason Barnett: Everything you need to know

The Athletics optioned Barnett to Triple-A Las Vegas on Friday. After coming up from the minors Wednesday, Barnett will return to Triple-A without making an appearance for the A's in order to make room for the newly acquired Jose Suarez. The 25-year-old Barnett owns a 3.07 ERA and 1.27 WHIP over 29.1 innings at Triple-A this season and remains an option to come up later in the year for a spot start or to give the Athletics length out of the bullpen.

The Athletics recalled Barnett from Triple-A Las Vegas on Wednesday. The 25-year-old will return to the majors to replace Brooks Kriske, who landed on the injured list Wednesday with a shoulder injury. Barnett pitched two shutout innings during his lone appearance with the A's this season in mid-April, and he owns a 3.07 ERA and 1.27 WHIP through 29.1 frames at Las Vegas. He'll likely take on a multi-inning role out of the bullpen while with the A's.

The Athletics optioned Barnett to Triple-A Las Vegas on Monday. Barnett needed 43 pitches to cover two-plus innings Sunday versus the White Sox in his lone appearance in the majors. Since Barnett would have been unavailable to pitch for a day or two, the Athletics have summoned a fresh bullpen arm to take his roster spot.
