Seattle Mariners Pitching Records First Franchise 3-Game Shutout Sweep

The Seattle Mariners recently achieved a historic pitching milestone by recording three consecutive shutouts for the first time in franchise history during a series sweep against the Pittsburgh Pirates. Their pitching staff combined for 36 strikeouts while allowing only 12 hits and 4 walks, setting an MLB record for a three-game span with no runs allowed, at least 36 strikeouts, and four or fewer walks. Starters Bryan Woo, Luis Castillo, and George Kirby were dominant, combining for over 19 innings of scoreless baseball with high strikeout totals and minimal walks, while the bullpen contributed nearly 8 scoreless innings. Despite this pitching dominance, the Mariners’ offense was underwhelming, scoring just one run in two of the three games and relying heavily on individual heroics like Cal Raleigh's two-homer game. Since mid-June, the Mariners have posted the second-best ERA in baseball, signaling a potential pitching-led turnaround as they aim to compete in the AL West and postseason. The recent success has provided a much-needed boost to the Mariners and their fans, highlighting the critical role pitching must play moving forward.
