Brentz (knee) returned to activity Friday, WEEI.com reports.

Brentz, who had missed a couple of days due to some inflammation in his right knee, was limited Friday, according to manager John Farrell. The manager expects Brentz to be full-go Saturday.

Brentz is dealing with right knee inflammation, the Boston Globe reports.

Brentz missed a second straight day because of the minor injury, but said he could play if games were scheduled. "We're just being careful," he said.

Brentz had a hit and an RBI in three at-bats in Friday night's loss to the Yankees. He has hit safely in three straight games.

Brentz will not figure into the crowded outfield in 2015, but he's certainly hasn't hurt himself since his September callup. The rookie has seven hits, two for extra bases, with two RBI and five runs scored in 18 at-bats.

Brentz made his major league debut Wednesday in a pinch-hitting role. He doubled and later scored Boston's only run in a 9-1 loss to Pittsburgh.

Brentz was once a shining power prospect in the organization, but has taken a hit the last two years. He still has the pop, but there have been problems with pitch recognition and plate approach. Then a hamstring injury limited him to 63 games at Triple-A Pawtucket in 2014. He showed some growth this year, increasing his walk rate, and he's hit well since returning from injury. Unfortunately, acquisitions at the major league level -- Yoenis Cespedes, Rusney Castillo, Allen Craig -- make his future with Boston unlikely.

Brentz was recalled from Triple-A Pawtucket on Wednesday, CSNNE.com's Sean McAdam reports.

The 25-year-old Brentz has largely fallen off the radar as a top prospect for the Red Sox, after posting back-to-back disappointing seasons at Pawtucket. He'll likely see only the occasional spot start or pinch-hitting opportunity with the Red Sox in the final week and a half of the regular season.

Brent went 2-for-3 with a walk, three RBI and three runs scored Monday night for Triple-A Pawtucket. Since returning from a hamstring injury, Brentz is 10-for-32 (.313/.353/.563) with two doubles, two homers and eight RBI in seven games.

The hamstring injury took a long time to heal, costing Brentz nearly two months worth of at-bats.

Brentz (hamstring) has been activated off the disabled list and is back with Triple-A Pawtucket, the Providence Journal reports. He made his first appearance in 10 weeks Saturday. Brentz had two hits in five at-bats in his return and then had three hits, including a homer and a double, in his second game back Monday.

Until a few days ago, the Red Sox were desperate for a right-handed hitting power bat in the outfield like Brentz. Now, the addition of Allen Craig and Yoenis Cespedes will block Brentz from any kind of full-time role in Boston this season and into 2015. It's probably for the best; Brentz lost a lot of development time this season and still has some work to do in terms of pitch recognition and being overly aggressive.

Red Sox outfield prospect Bryce Brentz hit his fifth home run of a season for Triple-A Pawtucket on Saturday.

The 25-year old Brentz is struggling in Triple-A for the second consecutive year, hitting just .208/.324/.392 with five doubles, one triple, and five home runs. Brentz hit .296/.355/.478 for Double-A Portland in 2012, but has struggled in Triple-A since his promotion at the end of August 2012.

Bryce Brentz hit his second spring homer off the Pirates' Justin Wilson on Monday.

Brentz is a legitimate outfield prospect, though one wonders if he'll ever be good enough to start for Boston's high-powered offense. Last year, he disappointed with his .312 OBP in Triple-A, but he did manage to collect 17 homers in 326 at-bats for Triple-A Pawtucket. As scarce as right-handed power is, he rates as valuable depth for the Red Sox.

Red Sox purchased the contract of OF Bryce Brentz from Triple-A Pawtucket.

An expected move, Bryce is now protected from December's Rule 5 Draft. The 24-year-old batted .264/.312/.475 with 17 home runs and 56 RBI over 82 games in Triple-A in 2013, a year which included a six-week absence after surgery to repair a torn meniscus in his right knee. He possesses raw power, but hasn't made much progress with his plate discipline.

Red Sox minor league outfielder Bryce Brentz is likely done for the season after undergoing surgery to repair the meniscus in his right knee.

The surgery was performed on July 16, and a six week recovery puts him back in action at the very end of the minor league season. The slugger hit .272/.321/.487 with 16 home runs for Triple-A Pawtucket this season and could be an option with the Red Sox next season.

Red Sox prospect outfielder Bryce Brentz (leg) is slated to begin playing in minor league games on Wednesday.

Brentz got a late start this spring after he accidentally shot himself in the leg while cleaning a handgun in January, but he's back to 100 percent. The 24-year-old outfielder is a .276/.335/.479 hitter over his first three professional seasons and was ranked as the organization's No. 8 prospect by Baseball America over the winter.

Red Sox prospect outfielder Bryce Brentz (leg) hasn't been cleared for full baseball activities.

Brentz is behind the other players in camp after he accidentally shot himself in the leg while cleaning a handgun in January. He is currently hitting and throwing on flat ground, but he has yet to spring at full speed. Still, the Red Sox expect him to be ready by the time minor league games begin on March 13.

Red Sox GM Ben Cherington said he wouldn't rule out Bryce Brentz (leg) appearing in games by the end of spring training.

Cherington confirmed that Brentz shot himself in the leg while cleaning a handgun, and is no longer on the spring training roster. However, the injury is not considered serious, and the Red Sox don't expect him to miss any time during the season. A supplemental first-round pick in 2010, Brentz spent the majority of last year at the Double-A level, where he batted .296/.355/.478 with 17 home runs and 76 RBI in 122 games (456 plate appearances).

Red Sox prospect Bryce Brentz told WEEI.com's Alex Speier that his absence from big league camp in spring training is due to an injury that he sustained from an accidental discharge of a gun he was cleaning.

The specifics of the injury aren't yet known, but Brentz said it's "nothing serious" and expects to be ready for the start of the minor league season. Brentz appeared in just five games at the Triple-A level in 2012, and likely would have been among the first cuts in spring training. While his path to the majors is currently blocked, he could make an impact with the Red Sox at some point in 2013.
