BOSTON (CBS) – The status of Red Sox third baseman Will Middlebrooks is unknown after he was forced to leave in the ninth inning of Sunday’s 2-1 extra innings win over the Mariners with hamstring tightness.
The team is not certain of the severity of the issue and did not comment Sunday evening. They will know more prior to opening a three-game series against the Athletics Monday night in Oakland.

Middlebrooks left with tightness in his left hamstring after stealing second in the top of the ninth inning. He was 0-for-3 on the afternoon with a walk.
The rookie also dealt with hamstring cramping earlier in the season, although the two injuries are thought to be unrelated.
In 48 games this season, Middlebrooks is batting .298 with 10 home runs and 37 RBI. Since the trade of Kevin Youkilis last Sunday, Middlebrooks is batting just .143 with a walk, home run, and seven strikeouts.
If Middlebrooks cannot go Monday night, Brent Lillibridge or Nick Punto could get the start at third.
