SAN FRANCISCO — San Francisco Giants outfielder Mike Yastrzemski was placed on the 10-day injured list on Friday with a strained left hamstring strain.
The move is retroactive to Thursday. Yastrzemski left Wednesday's game against San Diego with left hamstring tightness but had been expected to return within a couple of days after an MRI showed minor inflammation.
Yastrzemski had been one of the Giants' key offensive contributors during a recent 10-game winning streak. Over his last eight games, he batted .313 with four homers, 11 RBIs, nine runs, a double and three walks. He hit two home runs Monday night, splashing the game-winner into McCovey Cove in the 10th.
Infielder Isan Diaz was recalled from triple-A Sacramento to take his roster spot.
