Coulombe, battling to carve out a bullpen spot, pitched 2.1 scoreless innings in Thursday's 15-5 Cactus League victory over the Brewers, giving up just one hit and striking out two.
Coulombe looked like he was losing his grip on a roster spot just a week ago, but he's bounced back in his last two outings. The southpaw had surrendered at least one run in each of his first five appearances, but has now put together 4.1 scoreless frames across his last pair of trips to the mound.
