Kirby (9-9) earned the win Sunday, allowing two runs on four hits and two walks over six innings against the Pirates. He struck out five.
Kirby scattered just two hits through the first five innings as the Mariners provided the righty a 7-0 cushion. A Joey Bart two-run homer in the sixth was the first and only blemish against Kirby, who contributed his 16th quality start of the season. The 26-year-old righty put a halt to the Mariners' five-game skid, rebounding from allowing career highs in runs (11) and hits (13) against Detroit in his last start to allow two runs or fewer for the 17th time over 25 starts. He'll carry a 3.40 ERA and 1.08 WHIP into a scheduled home matchup next week against the Giants.
