BOSTON — Alfredo Aceves lost his winning streak and very likely his spot in Boston’s rotation all in one terrible night.
Aceves gave up eight runs in five-plus innings and lost for the first time in more than two years as the Red Sox dropped their third straight, 10-7 to the Chicago White Sox on Tuesday night.
And while Aceves (2-1) was struggling in Boston, righthander John Lackey was making a solid rehab start for Triple-A Pawtucket.
“It was a bad day for me,” said Aceves, who had his worst outing since joining the rotation when Lackey was sidelined with a strained right elbow.
After a pair of solid starts when he gave up just one run in each over a combined 11 innings, Aceves gave up four in the second, one in the third and fourth before he was chased during a four-run sixth.
“I don’t think he executed like he has been the last couple of outings,” Red Sox manager Terry Francona said. “Saying that, there were some balls that found some holes, the two walks.”
When asked for a report on Lackey, Francona said: “They actually had to keep him out there a little longer because he was so good.”
Then, the manager went on to say that “he’ll start Sunday.”
The problem was, Aceves didn’t seem to know.
“Every five days,” the righthander said when asked what’s next for him.
But, when asked what he’d do if he was asked to go to the bullpen, Aceves said: “I’ve been saying since spring training, I’m a pitcher.”
Lackey gave up one run in 5 2-3 innings, striking out four in a 63-pitch outing.
Alexei Ramirez tied his career high with four hits, and Philip Humber stymied Boston for seven innings.
It was Chicago’s sixth straight win at Fenway Park, its longest streak here since the “Go Go” Sox era of 1958-59.
Humber (4-3) scattered six hits in the first seven innings before giving up three more in the eighth as Boston cut the deficit to 10-5. In all, Humber was charged with four runs while walking one and striking out five in 7 2-3 innings — the first time in seven starts he has allowed more than three runs.
Chris Sale came on in the ninth after Boston cut the deficit to 10-7 and struck out Adrian Gonzalez looking on three pitches earn his second save.
Aceves allowed six earned runs on eight hits and three walks while striking out one. He had won 12 consecutive decisions for the Yankees and Red Sox in what had been the longest active streak since CC Sabathia in 2008.
But the White Sox scored four runs in the second, including a two-run single by Ramirez. He also singled and scored when Chicago scored four more in the sixth to chase Aceves and make it 10-1.
Ramirez had three RBIs while recording his second four-hit game in nine days. He also had the game-winning hit in the series opener Monday night, a two-run double that broke a sixth-inning tie.
Gordon Beckham had three hits for the White Sox, who have won two straight against Boston after losing four of their previous five games.
Despite their three-game losing streak, the Red Sox are 19-10 in May — the best record in the American League over the month. Adrian Gonzalez had 42 hits and 31 RBIs in the month, the first Red Sox player to top 40 and 30 in May, respectively, since Jim Rice in his AL MVP year of 1978.
Jason Varitek had three hits, including his second homer of the season. After Boston scored one more in the eighth on three hits off the Green Monster off Humber, Will Ohman relieved him and gave up a three-run homer to David Ortiz that made it 10-5.
Ohman got Mike Cameron, a defensive replacement for Carl Crawford, on a fly ball to right to end the inning. The Red Sox got two more in the ninth when Jed Lowrie walked, Varitek singled and, after Josh Reddick hit a sacrifice fly, Drew Sutton hit a high flyball that right fielder Brent Lillibridge couldn’t get at the Pesky Pole.
Sale came on and got Gonzalez on three straight pitches to end the game.
Notes: Crawford was out on an odd double play in the fifth, when he tried to steal second but had to turn back when Lowrie popped it up to center. The problem: Crawford had already taken a step toward third, and he didn’t touch second on his way back. … The Red Sox moved up the starting time of Saturday’s game against the Oakland Athletics to 1:10 p.m. from 7:10 p.m. so that fans will be able to also watch the Bruins in Game 2 of the Stanley Cup finals. The hockey game between the Bruins and the Western Conference champion Vancouver Canucks is scheduled to start at 8 p.m. Eastern time. … Chicago has won 12 of its last 14 at Fenway. During one stretch in 1958-59, the White Sox won seven in a row in Boston. … The Red Sox activated RHP Bobby Jenks from the 15-day disabled list and optioned RHP Michael Bowden to Triple-A Pawtucket. Jenks pitched a scoreless inning in relief. … Boston SS Marco Scutaro (side) has been cleared to resume baseball activities. RHP Daisuke Matsuzaka went for a second opinion on his injured right elbow. “Nothing new diagnostically. He’ll fly back and we’ll sit down with him to go over a course of action.” … Aceves won his last 10 decisions with the Yankees before signing with Boston in the offseason. He made 54 relief appearances and four starts since.
