Baltimore, MD (Sports Network) - Adam Jones' three-run eighth-inning double was the difference as Baltimore rallied late to top Boston, 6-3, in the finale of a four-game series at Camden Yards.

Kevin Millar drove in a pair while Aubrey Huff knocked in one and scored twice for the Orioles, who snapped a four-game losing streak.

Jim Johnson (1-2) notched his first major-league win despite allowing Boston's go-ahead run in the eighth. George Sherrill earned his 18th save with a scoreless final frame. Jeremy Guthrie allowed eight hits and two runs over 6 1/3 innings in his start.

Manny Ramirez went 2-for-5 with a home run for the Red Sox, who won the first three games in the series. Kevin Cash and Mike Lowell added an RBI each in the loss.

The Red Sox confirmed following Monday's contest that slugger David Ortiz has a partial tear of a tendon in his left wrist. According to a Boston newspaper, a source indicated that Ortiz's wrist will be immobilized for at least the next month to see if the injury can heal on its own.

"He has a partially torn ECU tendon sheath," Sox manager Terry Francona said. "He will not require surgery, but he will be placed on the disabled list. I can't speculate on how long he will be on there. I haven't been there."

Hideki Okajima (1-1) took the loss and was saddled with a blown save, charged with four runs on four hits in two-thirds of an inning.

"He got a lot of fastballs up and over the plate," noted Francona.

The Orioles wrapped up the game with a four-run eighth against the usually lethal Okajima.

Three consecutive singles from Nick Markakis, Melvin Mora and Huff loaded the bases, then Millar brought in a run with a sacrifice fly to right. Luke Scott grounded to first, and Kevin Youkilis threw to Cash who caught Mora in a rundown at the plate. Ramon Hernandez drew a walk to re-load the sacks and Jones laced a ball off the wall in left to clear the bases and put the O's ahead 6-3.

"He didn't chase pitches out of the strike zone," said O's manager Dave Trembley of Jones. "He showed real good poise. He didn't get himself out, he got himself into a good count. Late in the game that plays to your advantage and it did."

In the ninth, Sherrill allowed two-out walks to Julio Lugo and Youkilis but induced a game-ending fly out from Ramirez.

Baltimore broke a scoreless tie with a pair of runs in the fourth. Mora walked with one out, advanced to second on a passed ball and scored when Huff doubled to right. Huff came home on a base hit from Millar and Scott's infield hit put runners at first and second, but Hernandez lined out and Jones grounded out to end the inning.

Ramirez clubbed career home run 502 with one out in the sixth. He fought off an inside breaking ball from Guthrie and muscled it over the wall in right-center to bring the Sox within 2-1.

Cash tied the game with an RBI double in the seventh and the Sox went ahead in the eighth. Youkilis worked a leadoff walk then moved up to second on a Ramirez single. Lowell followed with a base hit to plate Youkilis for a 3-2 Boston edge.
