Pregame notes: Napoli day-to-day

BOSTON -- Some quick hits before the series finale between the Red Sox and Yankees at Fenway Park:

* Red Sox first baseman Mike Napoli remains day-to-day with a left foot injury.

“He needs today, obviously,” Farrell said. “We’ll reassess things when we begin the next series.”

Napoli was a last-minute scratch from the lineup Friday night against the Yankees due to his foot, which Farrell described as a lingering injury for the veteran first baseman.

* Red Sox DH David Ortiz will play two games at first base during the upcoming interleague series with the San Francisco Giants. How much he’ll play the field the following series against the Los Angeles Dodgers will depend on matchups. A lot also depends on Napoli’s availability moving forward.

* While the Red Sox will remain in Boston after tonight’s game in order to get a decent night's sleep before traveling to the West Coast at 10 a.m. Monday, pitchers Jon Lester, Jake Peavy and catcher David Ross are already en route to San Francisco.

* Red Sox left-hander Matt Thornton (right oblique strain) tossed a bullpen session Sunday afternoon at Fenway Park. Afterward, he said he felt good and he’s scheduled for another session on Tuesday.

“It put me in a good mood for the first time in about 10 days,” Thornton said.

If he continues to progress, he’ll likely throw a simulated game next Saturday while the team is in Los Angeles.

Farrell called Thornton’s Sunday session “a strong bullpen.”

* Even though MLB rosters expand on Sept. 1, Farrell said he’s only had preliminary discussions with GM Ben Cherington about possible call-ups. The organization has not decided on the number of promotions or the direction it will go, according to Farrell.

“We’re still a ways away from that,” Farrell said.
