Heaney (0-1) was charged with the loss Friday against the Mariners, allowing five runs on six hits and two walks while striking out 10 through 5.2 innings.
In just his third start since recovering from his elbow issues and coming off the IL, Heaney punched out 10 batters for the second straight game. The left-hander retired the first eight batters before giving up a pair of singles and a walk in the fourth inning to knot the score at 1-1. Heaney then allowed a home run to Domingo Santana in the fifth and a three-run homer to Tom Murphy in the sixth to give Seattle a 5-1 lead. The 28-year-old now owns a 5.40 ERA, 0.96 WHIP and 28:3 K:BB. He'll look to earn his first win Thursday against Tampa Bay.
