Doubront to start Friday; Ortiz gets day off

OAKLAND, Calif. -- Left-hander Felix Doubront will be activated from the 15-day disabled list Friday and start for the Red Sox against the Oakland A's in the second game of their four-game series.

Doubront will take the place of right-hander Brandon Workman, who is serving a six-game suspension for throwing near the head of Tampa Bay Rays third baseman Evan Longoria on May 30.

Doubront went on the disabled list May 21 with a strained left shoulder. In his last rehabilitation start for Triple-A Pawtucket on Sunday, he struck out 10 and allowed no hits over five innings.

"I felt great," Doubront said before Thursday's game. "Back in the minors, I was pitching, trying to get my arm speed and repeat my delivery more often and throw my pitches, get ahead in the count and strike somebody out. Get that confidence that I need to come back here. Everything went well."

Red Sox manager John Farrell said Doubront made big strides in his final rehab start.

"His last start was much improved in terms of overall stuff," Farrell said. "There was increased intensity, increased velocity, increased action to his pitches that are going to be required here. And he gets the ball tomorrow."

David Ortiz, who hit a game-tying home run in the 10th inning Wednesday against Minnesota, was out of the lineup Thursday night against Oakland.

"Just with the travel, as late as we got in here last night, not uncommon that he's got a day off where we try to manage his games with the first game on the West Coast," Farrell said. "Fully expect him to be back in the lineup tomorrow."

• Outfielder Shane Victorino (right-hamstring strain) was out of the lineup Thursday for Triple-A Pawtucket with "overall stiffness" in his lower back and hamstring but will still likely join the Red Sox while they're on the West Coast, Farrell said. After playing four games at Oakland, they play three at Seattle.

"He went through a full day of treatment," Farrell said. "We're going to go through another day of treatment tomorrow, likely, and everything points to him being back in the lineup on Saturday. We still intend that he will be joining us here on the West Coast. While he's not in the lineup, I can't say it was a setback, but we felt like we needed to get a couple days of work in."

• The Red Sox arrived in Oakland on the heels of an amazing victory Wednesday against Minnesota that Mike Napoli hopes can spark their struggling offense. Trailing 1-0 entering the bottom of the 10th inning, Ortiz and Napoli hit back-to-back home runs, lifting the Red Sox to an improbable 2-1 win.

"You hope it does," Napoli said. "That's what you look for: sparks to get your guys going. It was definitely a big win for us, and you would hope it would just snowball.

"It was just a crazy, crazy game. We were able to pull it out even though we weren't getting anything going offensively. Pitchers have been picking us up. It's time for us to turn the tables a little bit."

The Red Sox swept the three-game series against Minnesota despite scoring only five runs.
