As of Sunday, the Red Sox were carrying 12 position players and 13 pitchers, including eight relievers. Acquiring Jimenez affords the team another option off the bench while Brock Holt and Daniel Nava handle right field duties in place of Shane Victorino, who remains on the disabled list with a hamstring injury.
"It gives us some more flexibility with Brock and Daniel Nava. And hopefully the chance to get back to 13 position players," Farrell said.
Jimenez, who was designated for assignment on Saturday, went 1-for-15 with a walk in 15 games for the Brewers this season. The 27-year-old spent the previous seven seasons with the Angels' organization, primarily as a third baseman. He gives the Red Sox versatility on defense and some power potential at the plate, having hit .286 with 21 home runs for Triple-A Salt Lake in 2014.
"Right-handed utility guy that we like on defense, particularly at third if that comes into play," Farrell said. "He's also played some second, he's played some first. We feel like he can play shortstop in a short look."
Additionally, the Cubs claimed reliever Anthony Varvaro off waivers from the Red Sox, who designated the right-hander on Wednesday. Varvaro posted a 4.09 ERA in 11 innings with Boston this season.
