BOSTON -- Playing 5 1/2 innings of baseball in three days isn't the best way to stay sharp, and Red Sox manager Terry Francona knows it.

But when heavy rains left Fenway Park unplayable for a second straight day and the manager's bathroom wet, there was nothing left for the skipper to do but just look ahead.

"It depends on whether we win [Monday]," responded Francona, when asked if the consecutive rainouts were good or bad for his club. "It's what it is so it doesn't matter. I think with every team, nobody wants to get backed up."

While Saturday's game will be made up when the Rangers come back in June as part of a day-night doubleheader, Sunday's game could either be played in June or some other date later in the season. Both clubs have July 20 open and Francona suggested that day is a possibility.

"There's a small chance we could play Texas four games in two days, but I think that's probably a small chance. But at some point you're going to play a lot of games in a little bit of time," he said.

Francona isn't worried about player fatigue as much as he is about what impact the makeup dates will have on his roster -- especially the pitching staff.

"It's not the fact that guys get tired. It's hard enough to win as many games as you want when you're playing one, and it definitely messes with the [pitching] staff. You start playing five games in three days, what ends up happening is you have to make roster moves that cost guys time in the big leagues because you make moves you don't want to make."

John Blake, the club's vice president of media relations, said Sunday that MLB, the Players Association and the Rangers would try to work together to resolve the second makeup date in the early part of this week.

Sunday was the third Red Sox rainout of the season, all at Fenway Park. The club is one shy of the four home washouts in 2005. Sunday's rainout also marked the first time that Boston has been rained out on consecutive home dates since April 13-14, 2004, versus Baltimore.

Injury update: David Wells is scheduled to throw a simulated game on Monday afternoon at Oriole Park at Camden Yards. Wells has been on the disabled list since April 14 with right knee problems.

"He's going to throw a simulated game at 2:15 [Monday afternoon] in Baltimore," Francona said. "This has basically backed him up a couple of days. Talking to him [Saturday], I think he understood and maybe he thought [rainouts] wouldn't hurt him. Nothing we can do about it, anyways, so you might as well look at it like that."

The rain also threw a wrench into the plans to move reliever David Riske (strained lower back) along in his rehab. The right-handed reliever, who has already made one appearance for Triple-A Pawtucket, threw a 25-pitch simulated game in the batting cage Saturday, but rain washed out his chance to work in a game for the PawSox. He will make at least one more rehab appearance before the team makes a decision on whether to return him to the 25-man roster.

Coco Crisp continues to recover from an illness that Francona said left him "very, very sick." That sickness has pushed back his recovery from a broken left index finger, which continues to heal well. But the illness has kept him from getting back on the field and resuming many baseball activities.

"He's coming along slowly," Francona said. "He's not going to go with us on this trip. He's going to stay back and try to get his legs back under him."

Pregnant pause: Outfielder Dustan Mohr will miss Monday's game because his wife, Denise, will have labor induced. The couple is expecting a daughter.

No pink bats: The rain also cost Red Sox fans a chance to see Manny Ramirez and David Ortiz in a different light at the plate. Both sluggers were ready to go with pink bats from Louisville Slugger on Breast Cancer awareness day at Fenway Park as part of a Mother's Day tribute around Major League Baseball.

Coming up: Josh Beckett (4-1, 4.70 ERA) looks to continue Boston's dominance of the Orioles when the Red Sox open a three-game series Monday night at Camden Yards. Baltimore counters with right-hander Rodrigo Lopez (1-5, 7.03 ERA), who has already lost twice to Boston this year. The Red Sox have beaten Baltimore 11 straight, including all six meetings this year.
