YUNEL ESCOBAR homered off Boston closer Koji Uehara leading off the ninth inning to propel the visiting Tampa Bay Rays to a 6-5 win and a day-night doubleheader sweep of the Red Sox yesterday.

Escobar crushed the second pitch from Uehara (0-1) over the Green Monster for his second homer of the year, and Grant Balfour recorded the final three outs for his second save of the day and sixth of the season.

Sean Rodriguez and Desmond Jennings also went deep for Tampa Bay, which won for just the third time in nine games.

Jake McGee (2-0) earned the win with one inning of scoreless relief.

Tampa Bay won the opener, 2-1. David DeJesus had a homer and drew a bases-loaded walk, and the Rays' bullpen pitched 4 1/3 scoreless innings.

The victory wasn't without controversy, though.

With the Rays leading 2-1 in the seventh, Dustin Pedroia was called out on a close play at the plate, thrown out on a relay from Escobar at shortstop while attempting to score from first on Ortiz' double high off the Monster.

After a 1-minute, 52-second delay, it was announced the call "stands."

Boston third-base coach Brian Butterfield was ejected by first-base umpire Toby Basner for slamming his helmet to the ground.

Pedroia may have beaten catcher Jose Molina's sweeping tag with a feet-first slide, but it was unclear if he touched the plate before the tag.

Basner, rotating as the umpires moved on the play, made the call at the plate.

"I just don't like the whole inconclusive deal," said Pedroia, who didn't think he was tagged before crossing the plate. "Replay, you should go check it out and you're either out or safe. I don't know what inconclusive means. Maybe that means someone doesn't want to make a decision."

"I thought not only did Dustin beat the throw, beat the tag, but felt like his left foot made some contact with home plate," Boston manager John Farrell said. "Our video internally showed that, that was the case.

The second game was a bit smoother, but just as frenetic. Rodriguez' two-run homer off Boston starter Felix Doubront in the sixth brought the Rays within 5-4, and Rodriguez tied it in the seventh off reliever Junichi Tazawa, doubling and scoring on James Loney's single.

Boston threatened against Balfour in the ninth. Shane Victorino led off with a double and took third on Ortiz's groundout, but was stranded there when Balfour fanned Napoli and struck out Xander Bogaerts looking to end the game.

Noteworthy

* Two leaders of Major League Baseball's investigations unit are among five employees to leave following last year's drug inquiry that led to suspensions of 14 players. Dan Mullin, the senior vice president of investigations, and George Hanna, the senior director of investigations, are among those departing. They were hired in 2008 following the recommendation by former Sen. George Mitchell that MLB start an investigations unit. The department's initial focus concerned the use, possession and distribution of performance-enhancing drugs. MLB said the department is now handling "wide-ranging areas" and "felt compelled to restructure in order to increase the effectiveness and efficiency of its investigative capabilities."

* Kansas City is expected to place 37-year-old lefthander Bruce Chen on the disabled list with a swollen disc in his back. Chen said he's been dealing with back pain for weeks. He's already had an epidural to relieve some of the swelling, but so far it has not made the pain subside.

* Cincinnati placed lefthanded starter Tony Cingrani on the 15-day disabled list with a sore shoulder and recalled righthanded reliever Curtis Partch from Triple A. Cingrani is 2-2 with a 3.34 ERA in six starts.

* Baltimore reliever Troy Patton returned from his 25-game suspension (Adderall) and the Orioles activated third baseman Manny Machado (knee surgery) from the disabled list. They sent reliever Josh Stinson to Triple A. Also, the Orioles optioned infielder Steve Lombardozzi to Norfolk to make room for first baseman Steve Pearce.
