BOSTON -- The Rangers are switching Matt Harrison and Yu Darvish in the rotation. Darvish will pitch on Thursday against the Tigers and Harrison will pitch on Friday.
The move allows the Rangers to "split up" their left-handers, with Derek Holland pitching on Wednesday. But manager Ron Washington said that was not the reason why the Rangers made the switch.
"We wanted to keep Darvish pitching on four days' rest," Washington said. "He pitched, what, once a week in Japan? We want him to get used to four days down and then pitching on the fifth day. It just so happens to split the left-handers."
The Rangers were able to use Monday's off-day to make the switch. Darvish will start Thursday, and his following start will be on Tuesday against the Yankees at the Ballpark in Arlington. The Rangers are also off April 26, and that would give Washington another chance to juggle his rotation.
If Darvish pitches on four days' rest again, he would pitch April 29 against the Rays at the Ballpark. If the Rangers stay in rotation, Darvish would pitch April 30 in Toronto.
"We haven't gotten that far yet," Washington said.
Harrison will be pitching on six days' rest when he takes the mound on Friday. His last start was in a 4-1 victory over the Twins last Friday, and that left him 2-0 with a 0.64 ERA in two starts.
"You want to get the ball every fifth day," Harrison said. "I didn't work out that way, but I'll take a couple of extra days of rest and I'll be ready to go on Friday."
Moreland back with club after oral surgery
BOSTON -- First baseman Mitch Moreland was back with the Rangers on Tuesday after spending Monday in Dallas undergoing oral surgery. Moreland had an infected abscessed tooth, and he'll still need more dental work later, but he is ready to play again. He missed both Saturday and Sunday because of the problem.
"I'm so much better. It was a rough few days," Moreland said. "I probably got five hours sleep total in two days, but I feel 100 percent better. I slept great last night."
Moreland was not in the lineup on Tuesday. Manager Ron Washington decided to give Moreland an extra day with left-hander Jon Lester on the mound for the Red Sox. Mike Napoli started at first base for the second straight game, but Washington said Moreland will be back at first base on Wednesday against right-hander Josh Beckett.
Napoli went into Tuesday's game 5-for-9 with a home run in his career against Lester. Moreland has never faced him. Moreland is 2-for-5 with a home run against Beckett. Napoli will likely be behind the plate on Wednesday and again on Thursday when Yu Darvish pitches against the Tigers.
Ross shows back-to-back prowess
BOSTON -- Robbie Ross, pitching in relief, was the winning pitcher for the Rangers on Saturday and Sunday. That made him the first Rangers pitcher to win his first two Major League decisions in consecutive games.
Ross is also just the sixth Rangers pitcher to win on consecutive days. Steve Foucault did it twice in 1975, while Jackie Brown (1973), Steve Comer ('81), Jeff Russell ('91) and Wes Littleton (2007).
Manager Ron Washington was more impressed that Ross was able to go back-to-back without any trouble. He threw 15 pitches over two-thirds of an inning on Saturday and threw 25 pitches over two innings on Sunday.
"He's a resilient kid," Washington said. "He didn't show any wear and tear. It didn't affect him. That shows you he has a resilient arm."
Washington said Ross pitched two innings on Sunday because he thought the game was headed for extra innings. Instead, the Rangers won, 4-3, in nine innings.
"The game looked like it was going extra innings, so we were trying to use the bullpen as conveniently as we could," Washington said.
Washington was also pleased Joe Nathan was able to pitch back-to-back scoreless innings on Saturday and Sunday. He had allowed runs in two previous appearances in the second game of back-to-back outings.
"The good ones find a way to get back on track, and he's a good one," Washington said.
Rangers have five of first 93 picks in Draft
BOSTON -- Major League Baseball announced the order of the 2012 First-Year Player Draft on Tuesday, and the Rangers will have five of the first 93 picks. But because of Albert Pujols, only one will be in the first round.
The Rangers will have the 29th overall pick in the first round. They will also have two picks in the compensation round. They have the 39th overall pick as compensation for C.J. Wilson signing with the Angels and the 53rd pick for Darren Oliver signing with the Blue Jays.
The Rangers also get the Angels' second-round pick as compensation for Wilson. That will be the 83rd overall pick, but the Cardinals get the Angels first-round pick -- 19th overall -- for Pujols. The Rangers' second-round pick is 93rd overall.
The Rangers entered Tuesday's game with a 2.30 ERA, the lowest in the American League.
"The pitchers put a lot of work in during Spring Training, and they are reaping the benefits," said manager Ron Washington. 'Not all the work was physical, some of it was mental, and it shows."
Joe Nathan went into the two-game series with the Red Sox never having allowed a run in seven appearances at Fenway Park.
Neftali Feliz threw 11 scoreless innings to begin his career as a starter. That's the third longest such streak in club history. Alexi Ogando had 14 scoreless innings as a starter last season. Scott Chiamparino started his career with 12 scoreless innings in 1990.
Rangers relievers, going into Tuesday's game, had not walked a batter in 18 2/3 innings.
