After the White Sox went ahead, 3-2, in the eighth against Pedro Strop (5-2) on a run-scoring infield single by Adam Dunn, Baltimore answered in the bottom half against Brett Myers (2-2).

Mark Reynolds drew a one-out walk and McLouth drove a 1-0 pitch far over the wall in right-center. It was his third RBI of the game and second home run since the Orioles purchased his contract from Triple A Norfolk Aug. 4.

Jim Johnson pitched the ninth for his 40th save in 43 opportunities.

Facing the Orioles for the first time with Chicago after tormenting them as a member of the Red Sox, Kevin Youkilis hit a two-run homer in the sixth inning and singled in the eighth to set up Dunn’s RBI hit. Youkilis has a lifetime .322 batting average against Baltimore, with 23 homers and 87 RBIs.

The duel between the first-place White Sox and the surprising Orioles, who are in the midst of the AL wild-card race, attracted a meager crowd of 10,955 on a clear night at Camden Yards.

Blue Jays 8, Yankees 7 — Colby Rasmus hit a three-run homer off Rafael Soriano with two outs in the ninth inning and Toronto took advantage of Derek Lowe’s wild pickoff throw in the 11th to beat New York at Yankee Stadium.

Moments after Rasmus’s stunning drive put Toronto ahead, 7-6, Derek Jeter tied it with a home run off Casey Janssen. But the last-place Blue Jays didn’t cave, scratching out a run two innings later to stop an eight-game slide at Yankee Stadium.

The loss might have been a costly one in more ways than one for the AL East-leading Yankees. Slugging first baseman Mark Teixeira was pulled with a strained left calf and sent to the hospital for an MRI.

Rockies 10, Dodgers 0 — Jeff Francis and three relievers combined on a four-hitter as host Colorado spoiled the Dodgers debut of Josh Beckett.

Beckett (0-1) was acquired in a nine-player megadeal deal with the Red Sox over the weekend. His career in Los Angeles got off to an inauspicious start as he gave up a leadoff homer to Tyler Colvin on his second pitch, a 91-mph fastball that Colvin hit into the second deck.

The righty allowed three runs over 5⅔ innings as the Dodgers fell 2½ games behind idle San Francisco in the NL West.

Rangers 6, Rays 5 — Adrian Beltre was 3 for 3 with a home run and four RBIs, including the go-ahead run in the bottom of the fifth inning, to lead Texas.

Elvis Andrus scored on Beltre’s single to give the AL West leaders a series-opening win.

Nelson Cruz also homered and Mike Olt added an RBI for Texas.

Tampa Bay ace David Price (16-5) snapped a stretch of 12 consecutive quality starts in which he had pitched at least seven innings, giving up six runs on 10 hits in four innings.

Brewers 15, Cubs 4 — Aramis Ramirez hit two of Milwaukee’s five homers to lead the Brewers to a victory in Chicago.

Ramirez hit a two-run shot in the fifth and a solo homer in the ninth as Milwaukee beat Chicago for the sixth straight time.

Ramirez’s second homer followed a three-run shot by Ryan Braun that landed on Waveland Avenue, his NL-leading 35th of the season. Braun had four hits and five RBIs.

Corey Hart followed Ramirez with another shot that reached Waveland, giving Milwaukee back-to-back-to-back homers for the first time since Sept. 7, 2007 at Cincinnati.

The Brewers sent 14 batters to the plate and tacked on nine runs and eight hits in the ninth, finishing with a season-high 21 hits. Utilityman Joe Mather got the final out of the inning for Chicago, the first position player to pitch for the Cubs since Gary Gaetti on July 3, 1999.

Padres 3, Braves 0 — Casey Kelly combined with three relievers on a four-hitter to win his major league debut and Yasmani Grandal hit a two-run homer as host San Diego extended its season-high streak to eight straight wins.

The 22-year-old Kelly was the key player among the four obtained from the Red Sox in the trade for Adrian Gonzalez on Dec. 6, 2010.

Mariners 1, Twins 0 — Felix Hernandez struck out five in a five-hitter and Eric Thames hit a solo homer in the eighth inning to lift visiting Seattle.

Hernandez (13-5), who picked up his 23d career complete game and ninth shutout, hasn’t lost a decision since June 12. Franklin Gutierrez went 1 for 2 with two stolen bases in his first game since June 28 because of a concussion.
