BOSTON -- Yoenis Cespedes left Thursday's game against the Angels in the top of the third inning due to a family matter, the Red Sox announced.
"He was removed from the game due to a family medical emergency," said manager John Farrell. "A personal matter that he's dealing with. We're hopeful he'll be back in the lineup tomorrow. That's probably the most I can tell you right now."
Cespedes made his presence felt before exiting, making a strong throw to the plate to nail Josh Hamilton on a single to left by Howie Kendrick in the first inning.
In his only at-bat, in the bottom of the first, he struck out swinging.
The Red Sox acquired Cespedes on July 31 in a blockbuster trade with the Athletics for Jon Lester and Jonny Gomes.
In his first 18 games with Boston, he is hitting .229, with three homers and 13 RBIs.
Will Middlebrooks replaced Cespedes in the batting order and went to third base. Brock Holt moved from third to right, and Daniel Nava moved from right to left.
Middlebrooks wound up with Boston's only hit in a 2-0 loss.
