Coulombe gave up an earned run on one hit over one inning in Thursday's 3-0 Cactus League win over the Giants. He also recorded a strikeout.
Coulombe was saddled with his third loss of the spring as he continues to battle for a bullpen spot. The veteran southpaw had fired three scoreless innings Monday, so while Thursday's effort was somewhat of a setback, he may have already done enough to earn his place on the 25-man roster.
