BOSTON -- Rookie right-hander Jarrod Parker pitched 6 2/3 innings for his first major league win as the Oakland A's ended their three-game losing streak by hanging on for a 5-3 win over the Red Sox at chilly Fenway Park on Tuesday night.
Lefty Jordan Norberto got the last two outs with the tying runs on base to record his first big-league save.
The loss kept the Red Sox, winners of seven of their last nine, from climbing above the .500 mark for the first time this season. Boston fell to 11-12.
Mike Aviles chased Oakland closer Grant Balfour with a two-run single in the ninth, and the tying runs were on base when Norberto came on to strike out Lars Anderson and get Dustin Pedroia to ground out and end the game.
The A's had yielded 26 runs during the losing streak, 11 in Monday's night's series-opening loss to Boston. However, Parker, making his third big league start (second with the A's), yielded just four hits, walked two and struck out four. Brian Fuentes bailed him out of a jam in the seventh, as Oakland won for the 10th time in its last 29 games at Fenway Park.
A night after making two errors and hitting .181 coming in, Jemile Weeks doubled home two runs and scored another in a four-run second inning off Felix Doubront (1-1). The Boston starter lasted just four innings and suffered the loss despite a career-high eight strikeouts.
The A's stole third base four times in the game.
Doubront, who beat the White Sox his last time out after the bullpen blew a 9-1 lead for him against the Yankees April 21, struck out eight of the first 19 batters he faced. But it was the work of the other hitters and his own control that knocked him out after four innings.
Yoenis Cespedes singled home a run in the first before the A's struck for four in the fourth. With two out and two on, Cliff Pennington singled in a run and Jemile Weeks doubled in two. Weeks then stole third, Oakland's third steal of the night, and scored on Doubront's second wild pitch of the night.
The Red Sox got a run back in their half of the fourth on Pedroia's double and two groundouts. Parker then stranded two runners in the fifth.
NOTES: With Kevin Youkilis missing his third straight game with back stiffness, Boston recalled young shortstop Jose Iglesias from Pawtucket and optioned reliever Junichi Tazawa to the same team. Asked how serious Youkilis situation is, manager Bobby Valentine said, "I was with him today in the training room and there are times where it's pretty sore. Different movements, and he's doing everything he can in the training room. I'm not sure where we are with it. It seems like he has a situation that we just have to get over." ... The Red Sox announced the April 22 rainout against the Yankees will be made up as part of a day-night Fenway double-header July 7. ... Boston had until midnight to summon righty Aaron Cook from Pawtucket or risk losing him as a free agent. ... Valentine said righty Clay Buchholz "pitched through a blister situation" in Monday night's start, where he pitched well for six innings before yielding five runs in the seventh. ... Oakland manager Bob Melvin on Cespedes, the Cuban import in his first year in the United States: "You can literally see him learning on the fly, processing each and every pitch that's thrown to him. I see him each and every day finding new ways to prepare. I really marvel every day at the progress he makes." ... Both teams will wear 1936 throwback uniforms in the series finale Wednesday night as part of the 100th anniversary of Fenway Park.
