He may have earned himself another turn in the rotation.
Aceves (2-1) held the Phillies to one run over six innings in his best outing of the year, and the Boston Red Sox beat the Philadelphia Phillies 9-3 on Monday night.
"He took tonight as an opportunity to make an impression," Red Sox manager John Farrell said. "He made a solid one. It's a night-and-day difference."
Dustin Pedroia and Mike Napoli homered in the first inning as Boston jumped out to an early lead off Tyler Cloyd (1-1) and coasted to victory. Jacoby Ellsbury had hits in each of the first three innings to help the Red Sox earn their fourth consecutive victory and their 10th in the last 13 games.
Ellsbury also chased down Freddy Galvis' line drive to deep center field with the bases loaded in the sixth to end the inning and protect an 8-1 lead
"In this ballpark, when you're down four, maybe five runs, there's still a chance. But when it's 8-1, it's in another zone," Phillies manager Charlie Manuel said. "The ball Freddy hit when it was 8-1 might have gotten us close, but the guy made a pretty nice play on it."
Aceves was sent to the minors after allowing seven runs in an April 23 start against Oakland that ballooned his ERA to 8.66. But he was sent back to the mound on Monday because Buchholz had irritation in his shoulder and collar bone from sleeping awkwardly on his side.
Farrell would not say whether Aceves will get another turn in the rotation, but Buchholz is expected to miss only a few days and Franklin Morales is eligible to come off the disabled list Tuesday.
Aceves, who left the ballpark without speaking to reporters, gave up seven hits and three walks while striking out four.
"He looked like he was out there with a purpose," catcher Jarrod Saltalamacchia said.
Jimmy Rollins, Ryan Howard, John Mayberry and Ben Revere each had two hits for the Phillies. Erik Kratz's solo homer in the third and Domonic Brown's two-run shot in the eighth both curled around the Pesky Pole.
Cloyd allowed three runs in the first inning and was charged with three more in the third. He lasted just 2 1/3 innings, giving up nine hits and a walk while striking out two.
"When you really think about it, a loss is a loss," Manuel said. "We come back out tomorrow and it's still 0-0."
The Phillies made their first visit to Fenway since 2010, bringing along closer Jonathan Papelbon for his first trip to Boston since he left the team that he helped win the 2007 World Series. The Red Sox played a video on the scoreboard with highlights of Papelbon's career in Boston, but with the outcome long-decided by the ninth inning he did not get into the game.
Instead, the Red Sox largely put it out of reach early, getting Pedroia's two-run homer that also curled around the foul pole in short right field followed one out later by Napoli's long drive that cleared the Red Sox bullpen in right field by a dozen rows.
Boston made it 6-1 in the third. David Ortiz and Napoli doubled to lead off the inning, Stephen Drew singled in another run and, one out later, Saltalamacchia singled. With two outs, Jacoby Ellsbury doubled past a diving Revere in center field to score one run but Saltalamacchia was thrown out at the plate to end the inning.
Ellsbury, who hit a double to end Sunday's game, singled in the first and doubled in the second and third, giving him hits in four consecutive innings. ... Revere crashed into an unpadded part of the wall while catching Ortiz's deep drive to end the fourth. He stayed down and the trainer ran out to help him, but he remained in the game and singled in the top of the fifth. ... Cloyd had allowed three runs or fewer in six of his eight career starts, including all five on the road, before Monday. ... Daniel Nava was the only player in the Red Sox starting lineup who did not get a hit. ... The teams wore special camouflage uniforms and caps in honor of Memorial Day.
