SEATTLE -- J.D Drew continued his path back to the field with more batting practice. The Red Sox outfielder, who has been on the disabled list since July 20, again tested his left shoulder with more aggressive repetitions before Saturday's game.
"I'm building my endurance up," said Drew, who added that he felt better Saturday than Friday. "It's probably what I expected -- some soreness. I think I'll deal with that for the rest of the year. The strength gains help ... now I got to try to battle out of some bad habits."
Saturday's game marked the 23rd missed game for Drew. Manager Terry Francona said they'd check on the outfielder again Monday. As usual, the Red Sox will not take batting practice prior to Sunday's day game and the same goes for Tuesday's doubleheader and Wednesday's day game, so Drew will keep working in the cage.
Francona said Drew took 35 reps Friday and will continue to slowly increase that amount.
"I'm not going to overdo it to jeopardize taking steps back," Drew said. "For the most part, it's just building up endurance. Once we get to that point, we'll take the next step."
The 35-year-old veteran said that the injury stems simply from the "wear and tear of baseball" and inflammation in the rotator cuff. He had AC joint surgery a few years ago that also causes some immobility in the shoulder.
He added that surgery after the season is a possibility.
Drew is hitting .219 this season with four homers and 21 RBIs.
Youkilis 'still sore,' held out of Boston lineup
SEATTLE -- Red Sox third baseman Kevin Youkilis was held out of the lineup Saturday for the second consecutive game with a sore back.
"He's still sore," manager Terry Francona said. "We're going to stay away from him."
Shortstop Marco Scutaro, who was also scratched from Friday's lineup with a sore back, was in the lineup Saturday. Francona said the club would watch Scutaro during batting practice Saturday and make another evaluation.
Youkilis has now missed three of the last five games and six of the past 39 contests. He went a combined 1-for-8 in the Minnesota series and is hitting .267 this season.
Francona quite familiar with Pena's power
SEATTLE -- When you think of Wily Mo Pena on the Red Sox, the words "power" and "strength" might come to mind.
Terry Francona sure remembers it that way.
"Oh, boy ... some of the home runs he hit," Francona said of his former player who started at designated hitter for Seattle on Saturday. "He hit a ball in Baltimore ... it won the game for us. By the eighth inning, it was a day when the wind was blowing and I couldn't imagine someone hitting a home run that day.
"It's silly. Wily Mo's power is off the charts."
The 6-foot-3, 230-pound Pena was called up to Seattle from Triple-A Tacoma as a result of first baseman Justin Smoak's broken nose suffered during Friday's game. The 29-year-old played in Boston from 2006-07 and hit a career-high .301 in 2006 with 11 homers.
In his two seasons with Boston, Mo Pena hit .271 with 16 homers.
Tim Wakefield will try to become the 108th pitcher in Major League history to record 200 career wins on Sunday when he faces off against Seattle. His last three outings have been quality starts, but he's 0-1 in that span. The 45-year-old's last win came against Seattle at Fenway Park on July 24.
Red Sox manager Terry Francona said he doesn't want his players or himself thinking about records during games.
"I wouldn't say it's not in my mind, because I know. But you just can't," he said of thinking about the record in games. "It's not fair to the team. That's what makes part of it so special, like hitting streaks. You do it in the normal course of events. You don't try to change things."
David Ortiz has homered in four of his last seven games and is riding a small five-game hitting streak. He's .550 (11-for-20) with three jacks and seven RBIs in the last five contests.
So what does Big Papi think about his recent stretch of good play? Not much.
"What groove?" he said. " ... You know how baseball goes. You have ups and downs and you're going to be in it, you're going to be out of it, you're going to be in it, you're going to be out. But the most important thing is the consistency you can provide during the year.
"That's the most important thing. That's the only way you can win games."
