Drew will likely sit out until Red Sox hit road

BOSTON -- Red Sox shortstop Stephen Drew's hamstring will likely keep him out of the three-game series against the Padres this week.

Drew hasn't played since exiting Friday's game against the Blue Jays with a tight right hamstring, and though he has not been placed on the disabled list, manager John Farrell does not anticipate Drew to play before the Red Sox begin their West Coast road trip on Friday.

"He's improving," Farrell said. "He was able to get out and do some running today, some light jogging. But he's been responding favorable to treatment. [We] don't have a projected date this week when he'd get back on the field."

The Red Sox will continue to monitor whether Drew needs to be placed on the DL, Farrell said. If a move is made, a relief pitcher will likely get the call up because Boston currently has one more position player than normal on the roster.

"We're going to continue to stay as we are with out roster situation, but if there's any delays, then we'll adjust,' Farrell said. "But as of now, that's our approach."

Drew is batting .233 with five home runs, six triples and 31 RBIs this season.

Buchholz throwing, but no timetable on return

BOSTON -- It seems more and more unlikely Red Sox ace Clay Buchholz will return before the All-Star break.

The right-hander will need two rehab starts before returning to Boston's roster and Buchholz is still in the beginning stages of a throwing program he began after being placed on the disabled list.

"He threw out to 60 feet [Tuesday], which is basically the first step or the first day we have mapped out in the throwing program," manager John Farrell said. "No issues. The throwing program will be outlined to 60, 90, 120 at a varying number of throws or a progressive number of throws before we get him on the mound. We don't have a specific date right now that he would get back on the mound."

He will join the club on its West Coast road trip beginning Friday, meaning a rehab start before the All-Star break is not likely.

With a 9-0 record and 1.71 ERA, Buchholz has been dominant when healthy, but an awkward throw to first base he made during his last start on June 8 caused pain near his trapezius muscle, located at the base of the neck.

He originally tried to avoid a stint on the DL, but the injury hasn't healed as fast as he hoped. An MRI last week revealed no structural damage.

In Buchholz's absence, rookie Allen Webster will fill the rotation void. In four starts this season, he's 0-2 with a 9.50 ERA.

Farrell has learned plenty from Padres manager Black

BOSTON -- Former teammates and current friends are facing off during the three-game series between the Red Sox and Padres this week.

Red Sox manager John Farrell and Padres manager Bud Black played together on the 1988 Cleveland Indians and have maintained a relationship to this day. They chatted for about 10 minutes during batting practice before Tuesday's game.

"He's always been someone that I've learned a lot from as a teammate with and he's been willing to share some of his experiences, so, yeah, we've maintained a pretty close relationship," Farrell said.

The two skippers also share the distinction of being the only two current managers who were Major League pitchers.

When Farrell was preparing to jump from pitching coach of the Red Sox to manager of the Blue Jays, he turned to Black, who's managed San Diego since the 2007 season, for advice.

"There was a number of personnel-type discussions on construction of a staff and those types of things," Farrell said. "But even as a teammate there was always a perspective on his part that he always had a way to kind of slow the game down through our conversations, and I learned a lot for him. So whether it was in the same uniform or going to a similar role, it's a trusted perspective on his part."

Black said their pitching background gives them a similar managing perspective.

"I think there's probably a similar position bond that we have and how we view our managerial situations," Black said. "But I think at the end of the day, even going back to when we played together and our relationship personally, he's a good baseball man. He knows baseball. He's got a great baseball mind. He thinks like a player and that can combine both pitching and position player."

Farrell and Black are just two of the five current Major League managers who have roots from the 1988 Indians.

Farrell, Black, Indians manager Terry Francona and Rangers manager Ron Washington were players on the team, and Phillies skipper Charlie Manuel was the hitting coach.

"It just happened," Black said. "If you were to look at that group you wouldn't have predicted that. But each one of those four guys all have the attributes to lead."
