Brash, who started Monday's Cactus League loss to the Diamondbacks and fired two scoreless innings, is pushing to secure the Mariners' final rotation spot, Daniel Kramer of MLB.com reports.

EDGE Analysis

Brash got a fleeting first taste of the big leagues late last season, getting a call up from Double-A Arkansas during the final week but never appearing in a game. Despite his time with the Travelers qualifying as his highest level of professional ball yet, Brash, who allowed just a hit and a walk to the eight batters he faced Monday and flashed a 97.7 mph fastball, believes he can successfully make the jump right from the start of the campaign. The 23-year-old has yet to post an ERA higher than 2.55 in any of his five minor-league stops and also possesses an elite slider and an improving changeup in his arsenal.
