Pivetta dropped to 0-1 in Friday's 1-0 loss to the Mariners, allowing one run on three hits and zero walks while striking out 10 over six innings.
Pivetta was dominant, allowing his lone run on a J.P. Crawford solo homer in the sixth inning. However, the Red Sox couldn't solve George Kirby, saddling Pivetta with the loss. The 31-year-old right-hander is expected to be a major piece in Boston's rotation after going 10-9 with a 4.04 ERA, 1.12 WHIP and 183:50 K:BB last season. He's in line for a road matchup next week against the A's.
