The Boston-area forecast calls for a 100 percent chance of rain during the day and just as good a chance of heavy rain at night. The Yankees and Sox are supposed to square off on "Sunday Night Baseball" at 8:05 ET, with the Yankees looking to sweep. A reeling Boston team could use a reset day.
"The forecast is not real positive," Yankees manager Joe Girardi said. "It looks like we're going to see a lot of rain tomorrow."
If the game gets in, there's a lot on the line for Boston (4-10). The Sox have lost five in a row and on Monday will start a seven-game road trip through Minnesota and Chicago. After his team spoiled a 9-0 lead and fell, 15-9, on Saturday, manager Bobby Valentine said his team could not sink lower.
"I think we've hit bottom," Valentine said. "That's what I told them after the game. You have to sometimes hit bottom, and if this isn't bottom, we'll find some new ends to the earth, I guess, or something."
Despite the rivalry between the clubs, the Yanks (9-6) were not letting themselves ride too high on keeping the bad times rolling for Boston, according to Girardi.
"I don't think you ever get caught up in that," Girardi said. "They're a talented club. We've had situations where we've went bad. We weren't too good the first three days, and at any moment, things can turn around."
Daniel Bard is Boston's scheduled starter. While some fans may be clamoring for Bard to be shifted to the closer's role with the bullpen in shambles -- Sox relievers allowed 13 earned runs in two innings on Saturday -- general manager Ben Cherington said that Bard is still in line for his start. No plan for Bard has been devised if the game is rained out.
"It's really hard in this game to plan ahead for weather," Cherington said. "Daniel's starting tomorrow night. He's shown everything that he's had to show in the first two starts to give us a lot of confidence that he's going to pitch well tomorrow night. That's all there is to it right now."
The Yankees have ace CC Sabathia scheduled to start. Sabathia did not fare well against the Red Sox last season, letting up 22 earned runs in 31 innings across five starts. That amounted to a 1-4 record and a 6.39 ERA.
Yankees: Pineda suffers setback
Right-hander Michael Pineda suffered a setback in an extended spring start on Saturday, feeling discomfort behind his pitching shoulder.
Pineda's outing lasted just 15 pitches. He's expected to be seen by a physician in Tampa, Fla., on Monday.
"I think it's somewhat significant, just because you were expecting him to build up," Girardi said. "Now, you're going to have to give him probably a little bit more time than we did before. I can't tell you when we'll get him back now."
Red Sox: Byrd to join team on Sunday
The Cubs and Red Sox struck a deal on Saturday, with right-hander Michael Bowden and a player to be named dealt to Chicago in exchange for outfielder Marlon Byrd. The Sox need outfield help with Jacoby Ellsbury and Carl Crawford both out.
Byrd, hitting just .070 this season, is expected to join the Sox on Sunday. Bowden had been designated for assignment, and had he not been traded, the Sox likely would have lost him to another team on waivers.
"You know, he's been a good Major League center fielder for a long time," Cherington said. "He's off to a tough start, but our hope is that [with] a change of scenery, maybe a new environment, we can get him going and help us and give [Valentine] another option out in the outfield, with Ellsbury out and Crawford still coming back. We felt there was a need to add to the outfield, and hopefully he can help us."
Valentine's job does not appear to be in danger.
"Very satisfied," Cherington said on Saturday, addressing Valentine's body of work this season. "He makes the lineup out and he makes decisions during the game as to who's coming in. The players will always influence wins and losses more than anybody else. And that's no different here."
