Keller fired six scoreless innings without allowing a hit prior to being pulled in a 5-4 loss to the Cardinals on Saturday.
Keller was dominant, but he also racked up 84 pitches (52 for strikes) through six innings. With the Pirates' brass looking towards the future, Keller's arm was saved at the expense of the no-hitter. The 24-year old will carry a 3.24 ERA into his fourth start of the season, which is scheduled for Friday in Cleveland.
