Coulombe two-thirds of an inning in Sunday's 6-4 loss to the Rangers, recording a strikeout and allowing no runners.
The 27-year-old reliever has quietly become one of manager Bob Melvin's most trusted bullpen options, turning in scoreless efforts in six of his last seven appearances. Coulombe is now sporting a solid 2.77 ERA, and his value as a southpaw has risen exponentially in the prolonged absence of fellow lefty Sean Doolittle (shoulder).
