Poor air quality in Cleveland led to the postponement of the Pirates/Guardians game, which will now be played as a split doubleheader today. The Red Sox extended their win streak to 11 games with victories over the Rays, bringing their record to .500 for the first time this season. In notable games, the Nationals defeated the Athletics 23-4, with Andres Chaparro contributing eight RBI, while the Royals achieved a dramatic 7-6 walkoff win against the Padres.
