Ryan Mountcastle hit a tiebreaking RBI double in the seventh inning and scored on an infield hit to lead the AL East champion Baltimore Orioles to their 101st victory of the season, 5-2 over the last-place Boston Red Sox on Saturday night.
Baltimore (101-60), which hosts an AL Division Series starting Oct. 7, is finishing its winningest season since going 102-57 in 1979.
“I want our guys to understand how great of an accomplishment that is,” manager Brandon Hyde said. “We won every series against the AL East. That’s an incredible accomplishment as well with all the talent, how good the teams are in our division.
