Middlebrooks, who hit well in his time at Triple-A Colorado Springs, has struggled in his limited work with the Brewers this season. It's unclear how much time the 27-year-old third baseman will miss, but he will have to play well and prove he's fully healthy in his rehab appearances to steal time away from Hernan Perez, who has been playing really well at the hot corner for Milwaukee.
Franco (wrist) entered Sunday's game in the fifth inning after Andres Blanco broke his finger.
Franco was out of the starting lineup Saturday and Sunday because of a sore wrist. He finished out Sunday's game at third base and went 1-for-2 at the plate. It looks like he should be able to return to the starting lineup Monday.
Manager Mike Matheny suggested Sunday that Carpenter (oblique) could head out on a rehab assignment within the next few days, Jennifer Langosch of MLB.com reports.
Carpenter has missed approximately three weeks because of the issue at this point, so he may require more than a couple games before returning to the big league squad. An early August return seems plausible if he indeed begins his rehab assignment in the near future, but a return date should firm up as it draws closer.
Worth was designated for assignment by the Astros on Sunday.
Since joining the Astros, the 30-year-old has posted just a .442 OPS over the course of 15 games (38 at-bats). The move came following Sunday's contest, when Marwin Gonzalez left with an ankle sprain. While there may be no correlation, Houston will look to improve their offensive production, adding Alex Bregman, one of the team's top prospects, potentially as an everyday utility man.
Updating a previous report, Middlebrooks left Sunday's game early due to a lower right leg strain.
It doesn't sound like the ailment is overly serious, but it wouldn't be surprising to see Middlebrooks rested Monday against Arizona. If he does end up being unavailable, Hernan Perez and Jake Elmore are both candidates to get the start at third base.
Middlebrooks left Sunday's game in the fourth inning with an apparent leg injury, Todd Rosiak of the Milwaukee Journal Sentinel reports.
Middlebrooks popped out to second base on the play and injured himself somewhere along the way. He needed to be helped off the field by teammates and appeared unable to put much weight on the leg. According to the live broadcast, the injury appears to be something related to his calf, which may indicate a cramp due to the high level of humidity in Milwaukee on Sunday. Consider him day-to-day in advance of Monday's series opener against the Diamondbacks.
