The Seattle Mariners enter their late-May AL West series against the Athletics with a 25-29 record, sitting 2.5 games behind the division-leading A's at 27-26. Mariners pitching has faced recent instability, including left-hander Gabe Speier on the injured list with shoulder inflammation, while infielder Brendan Donovan deals with a left groin strain. The Athletics, hosting at Sutter Health Park in Sacramento, feature a rotation led by Aaron Civale and have posted improved run prevention lately despite inconsistent offense. Earlier April matchups between the clubs produced multiple one-run decisions, underscoring the competitive divisional rivalry and potential for tight contests driven by bullpen reliability and starting pitching matchups.
