BOSTON -- Mike Cameron's three-week stint as a spectator will come to an end on Monday, when the outfielder starts a rehab assignment with Triple-A Pawtucket.

Boston's starting center fielder, who has been down since April 19 with a lower abdomen strain, will DH in Pawtucket's home game, which starts at 6:15 p.m. ET at McCoy Stadium. Assuming there are no setbacks, he will play center field on Tuesday. The Red Sox have a day game on Wednesday, so Cameron will come to Fenway that day and consult further with the club on how much more time he needs.

"I'm going to DH tomorrow and just get a true feel for where I'm at, and run around and go play the game," said Cameron. "Once the game starts, I'll have to go full speed. Just athletically and with natural baseball reaction, I need to go see where I'm at -- run around, dive and kind of see what the field is like, where I'm at. I just have to be brutally honest with myself and brutally honest with the staff."

How many games will Cameron need before he is activated by the Red Sox?

"It's all based on what's going to take place," Cameron said. "I feel good. My body feels good. It's been responding to back-to-back days of constant pounding. Other than like general soreness, I've got to let it go. It's probably the next step I need to take as far as, can I play big league baseball the way I feel like I need to be able to play?"

The Red Sox have not only been without Cameron, but also starting left fielder and leadoff man Jacoby Ellsbury, who hasn't played since April 11 because of a chest contusion and hairline fracture in four left ribs.

Manager Terry Francona said that Ellsbury is making progress, but not quite ready to play in games yet.

"It's about kind of like we said -- he's not quite ready to do that but he's getting a lot closer," Francona said. "Ells is doing a lot better. He's getting there. He's just not quite ready to go play."

Hermida continues to deliver big hits

BOSTON -- Though the Red Sox hardly wanted to lose invaluable leadoff man Jacoby Ellsbury for any length of time, his primary replacement in left field continues to get big hits.

In Sunday's 9-3 win over the Yankees, Jeremy Hermida went 2-for-4 with a homer and three RBIs. He also hit a bullet to left field in the second inning that brought home a run, but it was ruled an error.

Hermida has driven in nine runs in six games in May. He is hitting .243 with four homers and 19 RBIs.

"We've got a long way to go," Hermida said. "I'm just taking it day by day. It's always nice to help the team."

"He's done some good things for us," said Red Sox manager Terry Francona. "Even when his average has come down a little bit, he's had a lot of production. He's gotten some big hits for us. He's done a really good job, so has [Darnell McDonald]."

Hermida has had a penchant for delivering his hits at important times.

"I agree with that," Francona said. "He's had a couple of pinch hits. He's done a really good job. He swings at strikes. He's got the power potential. He's been an everyday player for a lot of his career. So it's not different for him now -- he's been playing a lot. He's got some big hits for us."

Beltre blocks out wind with glasses

BOSTON -- Adrian Beltre wore glasses for his final three at-bats in Sunday night's 9-3 win over the Yankees, but it had nothing to do with his eyesight.

It was an unusually windy and chilly night at Fenway, so Beltre was just trying to protect himself from the elements. It worked out pretty well, as he crushed a pair of doubles -- the first of which scored two runs -- with the glasses.

"My eyes are really sensitive, and every time it's windy, I can't see," Beltre said. "Today the wind was really bad. It was the first time I've ever worn them. Ever. I've had them for many years, but I've never used them."

Beltre said that the glasses had no prescription. They were Oakleys.

"Seattle was really cold, too, and the wind would always come out to left field -- but I never had the guts to use them," said Beltre, who played the previous four years for the Mariners. "I'll probably use them more often."

Ramirez's triceps feeling better

BOSTON -- Red Sox reliever Ramon Ramirez, who left Saturday's game with tightness in his right triceps, was feeling much better on Sunday. That said, manager Terry Francona will likely wait until Monday to use his right-hander again.

"I feel good. I played catch earlier and felt normal," Ramirez said through interpreter and teammate Manny Delcarmen.

Ramirez gave up a home run to Mark Teixeira and threw just one pitch to Alex Rodriguez in Saturday's game before feeling the tightness.

"It just happened all of a sudden, but I've never felt like that before," said Ramirez. "They took me out just to make sure it didn't get worse."

It has been an inconsistent season thus far for Ramirez, who has a 5.93 ERA.

"I've felt good for the most part," said Ramirez. "I pitch well sometimes. You know how baseball goes. I'm glad I'm healthy and I'll try to move forward."

A day after being forced to use outfielder Jonathan Van Every as a pitcher in Saturday's blowout loss, Francona felt his bullpen would be fine on Sunday. Closer Jonathan Papelbon and lefty setup man Hideki Okajima didn't pitch on Saturday. Neither did Tim Wakefield, who is available for Sunday night's game after pitching three innings on Friday.
