The last time Mitch Keller pitched in a competitive game, his team ended up celebrating a championship.
Even without that kind of pressure, Keller was still sharp in his first Arizona Fall League start. Pittsburgh's No. 2 prospect worked around three hits and a walk while striking out four in three scoreless innings as Glendale edged Peoria, 5-4, at Camelback Ranch.

Keller's first matchup of the campaign might have been his toughest. Top Braves prospect Ronald Acuna. MLB.com's fifth-ranked overall prospect fouled off the first pitch as he worked a full count, but the No. 18 overall prospect retired him on a swinging strikeout. Acuna followed up with a first-pitch single in the third.
Red Sox No. 2 prospect Michael Chavis singled off Keller in the first and Mariners prospect Eric Fillia slapped a ground-rule double in the second, but Keller shut down the Javelinas from there.
