Daniel Mengden tossed seven hitless innings on May 16, 2026, guiding the Oakland Athletics to a 9-2 win that completed a four‑game sweep of the Toronto Blue Jays. The victory pushed the A’s record to 32‑24 and kept the AL West race alive.
The A’s improved to second place in the AL West, narrowing the gap to the Houston Astros to three games while Toronto slipped to 28‑30 in the AL East. It was the club’s first four‑game sweep since July 2022, underscoring a mid‑season turnaround.
What sparked the A’s dominance?
After a 5‑13 loss on May 12, the front office added veteran reliever Blake Treinen, shoring up the bullpen and allowing Mengden to work deeper into games. The trade was a catalyst, and the A’s responded with back‑to‑back wins, highlighted by a ninth‑inning surge on May 14 that turned a 4‑4 tie into a 6‑4 victory.
