The Red Sox removed star right fielder Mookie Betts from the lineup just minutes before the first pitch of Sunday's game against the Braves due to left side tightness.
He is day to day.
Betts has been Boston's best player this season, and arguably the best in the game, slashing .359/.437/.750 with 17 homers and 37 RBIs.
Red Sox did a major reshuffling of the lineup after Betts was scratched. Andrew Benintendi moved to leadoff and played center instead of left. Jackie Bradley Jr. moved from center to right. Blake Swihart was inserted into the lineup due to the absence of Betts and batted seventh while playing left field.
Second baseman Dustin Pedroia, in his second game back from the disabled list, batted cleanup.
J.D. Martinez, Boston's most productive hitter besides Betts, was also out of the lineup on a regularly-scheduled day off.
