Alfredo Aceves has been placed on the disabled list with Triple-A Pawtucket due to an oblique strain.

Aceves has been on the inactive list since he was outrighted to Triple-A last week. There's no timetable for his return, but he's expected to pitch out of the bullpen once he's back to full health.

Red Sox manager John Farrell said Thursday that Alfredo Aceves will pitch out of the bullpen with Triple-A Pawtucket moving forward.

Aceves, who has a 4.86 ERA over 11 appearances (six starts) with the Red Sox this season, was outrighted to Triple-A over the weekend. He'll need to be added back to the 40-man roster in order to get another call-up.

Red Sox sent RHP Alfredo Aceves outright to Triple-A Pawtucket.

The move clears a spot on the 40-man roster. Aceves has a 4.86 ERA in 11 appearances (six starts) with the Red Sox this season.

Aceves pitched well again in a spot start Tuesday, but the Sox needed him just for that outing. He'll be back later this summer.

Alfredo Aceves pitched five innings of one-run ball for a victory in the first game of Tuesday's doubleheader against the Rays.

Aceves was at just 75 pitches when the rains came and ended his outing. He walked three today, all in the second inning. That was when the run scored, too. Other than that, he was excellent for the third straight start. Whether he'll get another one anytime soon is up in the air.

Aceves will start the first game of Tuesday's day-night doubleheader against the Rays. The 31-year-old owns a 5.58 ERA and 22/19 K/BB ratio over 30 2/3 innings at the major league level this season.

Alfredo Aceves will start the first half of Tuesday's doubleheader against the Rays.

Aceves held the Rays to one run over six innings last Wednesday and is a decent streaming option for those in AL-only leagues. The right-hander has allowed just two runs over his last 13 major league innings.

Alfredo Aceves will start one of the games during Tuesday's doubleheader against the Rays.

It's no surprise after he limited the Rays to one run over six innings last week. Aceves has pitched well in each of his last two spot starts and isn't a bad streaming option in AL-only leagues.

Aceves will likely be brought back up to make a start during next Tuesday's doubleheader with the Rays. He limited Tampa Bay to one run over six innings Wednesday.

Alfredo Aceves limited the Rays to one run over six innings to earn the victory on Wednesday.

Aceves allowed four hits and four walks but was tagged for just an Evan Longoria solo home run for the Rays' only run of the game. It's the second-straight start in which the right-hander has gone six while allowing just one run -- the last was on May 27, as he's been mostly relegated to spot-start duty this year -- and the victory moved him to 3-1 despite an unsightly 5.58 ERA.

Aceves will make the start Wednesday night against the Rays. The 31-year-old has a 6.57 ERA in 24 2/3 innings with the big club this season and can be avoided in most fantasy leagues.

Alfredo Aceves is expected to join the Red Sox active roster to start Wednesday against the Rays.

Aceves threw six innings of one-run ball in his last spot start but is not a great fantasy bet. The right-hander has a 6.57 overall ERA in 24 2/3 big league innings this year.

Aceves threw six innings of one-run ball Monday in a spot start against the Phillies, but the Red Sox needed to clear a roster spot for Franklin Morales. Aceves should be back up in the majors within a couple weeks.

Making an emergency start with Clay Buchholz sidelined, Alfredo Aceves pitched six innings of one-run ball to beat the Phillies on Monday.

When Aceves's head is on right, his rubber arm and ability to pitch in any role make him valuable to a major league team. The Red Sox likely would have given him to any team interested in taking on his salary earlier this month, but no one stepped up, which might prove fortunate for Boston. Of course, he's still a leading candidate to be sent down this week with Franklin Morales set to come off the DL.

Aceves put up a 3.13 ERA while striking out nearly a batter per inning in four starts for Pawtucket. He'll be used in long relief for the Sox.

Alfredo Aceves has reported to Triple-A Pawtucket.

The Red Sox unsuccessfully shopped Aceves, but he predictably didn't draw any trade interest. He was optioned to the Triple-A level on Wednesday after posting an 8.66 ERA and 2.09 WHIP over 17 2/3 innings. Aceves is expected to be used as a starter in the minors and should return as a swingman later this season.

Alfredo Aceves will be used as a starter at Triple-A Pawtucket.

"The capability is there. Yet we've got to get him back on track. Not just inning to inning but outing to outing," Red Sox manager John Farrell said. "He is a depth starter for us. Whether that's 6, 7, 8, or 9 is more predicated on rest and who's available on a given day. He goes back to that role." The Red Sox will try to trade Aceves first, but it's unlikely that they'll find any willing partners.

Alfredo Aceves is expected to report to Triple-A Pawtucket within the next 72 hours.

Aceves was officially optioned to the Triple-A level on Wednesday after posting a brutal 8.66 ERA and 2.09 ERA over 17 2/3 innings with Boston. If he doesn't report to Pawtucket, he will not get his $2.35 million salary. The Red Sox are reportedly trying to trade the 30-year-old right-hander, but they're doubtful to find much of a market.
