Steve Pearce had the official go-ahead knock with a solo home run in the sixth inning that broke a 2-2 tie, which reliever Joe Smith gave up to take the loss. The Red Sox scored five times in the eighth to pull away, as closer Roberto Osuna struggled in unfamiliar territory. After Osuna got the first two outs, he walked a batter, gave up two singles, hit Brock Holt with a pitch to force in a run, and then gave up the grand slam.
The Astros started controversy on Monday involving the Red Sox starter, as Alex Bregman posted a video to Instagram of the Red Sox hitting back-to-back home runs off of Eovaldi. He would later take the post down, which will now for sure stay down after Tuesday's loss.
Bradley's big long ball helped him stay hot in the series, as he also drove in three with a double in the Red Sox's Game-2 victory. The outfielder now has three RBIs in consecutive games for the first time in his career, which led to the chants of "JBJ" during the Boston Celtics' season opener against the Philadelphia 76ers.
Dallas Keuchel got the start for the Astros and gave up two runs in the first, which continued his early-game troubles. The starter gave up 26 runs in the first inning during the regular season, giving him a 6.88 ERA in that frame for the year. The Astros will go with Charlie Morton in Wednesday's Game 4, as he will be opposed by Rick Porcello.
