Middlebrooks (hamstring) said that he wasn't 100 percent before Thursday's game that he ultimately sat out for, but he could have played if needed, Scott Lauber of the Boston Herald reports. Middlebrooks' injury has been downplayed throughout its entirety, so his potential return to the diamond is a real possibility against the Mariners on Friday. If he's unable to play yet again, Brock Holt seems like the probably replacement.

Middlebrooks (hamstring) remains out of the lineup Thursday against the Angels, Alex Speier of WEEI.com reports. Manager John Farrell previously indicated that a long absence didn't appear in the offing for Middlebrooks, but a stint on the DL probably isn't off the table completely just yet. He'll be evaluated closely over the next couple of days, with the team plugging in Brock Holt at third base until Middlebrooks is deemed ready to return.

Middlebrooks, who isn't in the lineup Wednesday, was diagnosed with a hamstring strain, but isn't expected to miss much time, the Boston Herald's Scott Lauber reports. "We don't feel like this is a long-term thing," Farrell said. "But we'd be putting him in jeopardy if we were to start him tonight." He left Tuesday's game with tightness in his right hamstring, and should be considered day-to-day for now. Utilityman Brock Holt will get the start at third base Wednesday.

Middlebrooks (hamstring) is out of the lineup Wednesday versus the Angels, Brian MacPherson of the Providence Journal reports. Removed from Tuesday's contest due to a tight right hamstring, Middlebrooks will remain sidelined in the short term. In his place, Brock Holt will cover the keystone and bat leadoff.

Middlebrooks left Tuesday's game against the Angels with right hamstring tightness, Pete Abraham of the Boston Globe reports. Although Middlebrooks managed to beat out an infield in the fourth inning, he hurt his hamstring in the process and was immediately lifted for a pinch runner. The Red Sox are labeling the injury "tightness" for now, but it would make sense if they sent him for additional testing. Brock Holt and Kelly Johnson seem like the top candidates to see opportunities at third base should Middlebrooks miss time, though Xander Bogaerts is an option as well.

Middlebrooks left Tuesday's game against the Angels with an apparent injury, Pete Abraham of the Boston Globe reports. Middlebrooks appeared to be in some discomfort after beating out an infield single in the fourth inning and he was promptly lifted for a pinch runner.

Middlebrooks is out of the lineup Saturday against the Astros, Pete Abraham of the Boston Globe reports.

Middlebrooks entered Wednesday's game as a pinch hitter and struck out in his only at-bat. He's gone 1-for-15 with seven strikeouts over his last four games. Kelly Johnson got the start Wednesday, but moved to left field when Yoenis Cespedes left the game with a hand injury. With manager John Farrell needing to get Brock Holt in the lineup everyday, a struggling Middlebrooks makes that task easier. Middlebrooks needs to generate sustained success against major-league pitching over the final month-and-a-half, or he'll find himself out of the team's plans for 2015.

Middlebrooks is not in the lineup for Wednesday's game against the Reds, according to Pete Abraham of the Boston Globe. Middlebrooks started the last five games at the hot corner, but he went just 3-for-22 (.136) during that span, so manager John Farrell decided to hold him out Wednesday. Kelly Johnson will start at third base for the Red Sox on Wednesday afternoon.
