Arizona Diamondbacks outfielder Corbin Carroll exited Sunday's 10-4 loss to the Toronto Blue Jays before the fifth inning due to low back tightness. The two-time All-Star struck out in the third inning after a swing that prompted visible discomfort, as seen in video replays. He attempted to stretch during the fourth inning before being replaced by Jorge Barrosa.

Carroll, 25, has been a standout performer this season, batting .300 with three home runs, 16 RBIs, and a .990 OPS. His recent form includes a go-ahead grand slam in Saturday's 6-2 victory over Toronto. Diamondbacks manager expressed concern over Carroll's health, noting his critical role in the lineup. Carroll's absence raises questions about Arizona's outfield depth, particularly with Barrosa, a utility player, filling in. The injury timing is concerning as the Diamondbacks aim to solidify their playoff positioning in a competitive NL West race.
