Red Sox-O's rained out; day-night twin bill Saturday

Lester to start Game 1 at Fenway, with Lackey scheduled to pitch in nightcap

BOSTON -- The Red Sox got a rare July 4 off-day after Friday's game against the Orioles was postponed due to inclement weather associated with Tropical Storm Arthur.

The teams will instead play a day-night doubleheader at Fenway Park on Saturday, with Game 1 at 1:05 p.m. ET, and the regularly scheduled game serving as the 7:15 p.m. nightcap.

Fans who had tickets for Friday can use them for Game 1 on Saturday.

Ace lefty Jon Lester will pitch Game 1 for Boston, followed by John Lackey in Game 2.

The only ramification the rainout has on Boston's rotation is that the club will now need to find a starter for Wednesday's game against the White Sox, as both Lester and Lackey won't be available until Thursday.

Rubby De La Rosa, who did a stellar job filling in as a starter when Clay Buchholz was on the disabled list, could be a candidate. So, too, could lefty Felix Doubront, who was recently moved to the bullpen.

"Again, we haven't taken a look at everything," said manager John Farrell. "We'll need an additional pitcher even if we choose to spot start somebody, so we'll figure that out as we get through the weekend."

The Red Sox had a scheduled off-day Thursday, meaning they will be well-rested when they take the field for the doubleheader.

The first game will be televised on NESN, with Game 2 a national game on FOX.

Given the forecast, there never seemed like much of a chance that Friday's 1:35 p.m. matinee would be played, and it was called around 10 a.m.

Most of the players at least got in a light workout before going home to spend the holiday with their families.

"Everyone was here," Farrell said. "There was certainly enough talk even throughout the day [Thursday] as I reached out to a few guys that this was a possibility today. But everyone was here and guys got their throwing in that needed to."

The Red Sox will be able to add a player to the roster for Game 2 on Saturday, though Farrell said that player has yet to be determined.
