Mike Napoli is back at first base for the Red Sox today.
Napoli exited Thursday's game in Baltimore in the third inning because of illness. He did not play the rest of the four-game series, and returned to Boston on Saturday to be examined by team doctors when his symptoms continued.
"He's obviously improved to the point to be in the lineup today," John Farrell said.
The manager also expects Mike Carp to be available tonight. Carp left Sunday's game in Baltimore in the seventh inning with a cramp in his right hamstring.
Clay Buchholz (sore right trapezius) will throw on today and it will be "increased intensity" compared to what he threw in Baltimore, Farrell said. The coaching staff will evaluate the pitcher's progress to determine whether he will be available later this week or is headed for a stint on the disabled list.
Buchholz has not pitched since he left a start on June 8 because of the issue.
"Today would be the day for him to get off the mound if he's going to be eligible sometime later this week," Farrell said. "If not, we're probably looking at a roster move."
Farrell said it is "not likely" the roster move would occur between games on Tuesday.
The Red Sox need a starter for Saturday's game in Detroit, whether it's Buchholz or somebody else.
"For [Buchholz] to be able to make that start, he would need to bullpen today, Thursday, and then start Saturday," Farrell said. "If the bullpen can not be executed today, then we will make a move."
Farrell said the organization has narrowed in on two candidates as potential fill-ins: Rubby De La Rosa or Allen Webster.
