BOSTON -- The Red Sox again dipped into their stock of young arms in Triple-A Pawtucket to help their taxed bullpen.
The latest move was to recall right-hander Rubby De La Rosa and demote Pedro Beato, who gave up the go-ahead home run to Arizona's Cody Ross in Boston's 7-6 loss Friday night.
Due to a 15-inning game on Wednesday and a pair of less-than-impressive starts by Ryan Dempster and Jon Lester the next two games, the bullpen has worked 15 2/3 innings over the last three nights.
The Sox have been in these situations before, and more times than not, bringing up a reliever from their farm system -- even if it has been for a short stint -- has worked out for them. Drake Britton, Brandon Workman, Beato and most recently Steven Wright have all been solid filling in this season. Having that many young arms ready to contribute is something manager John Farrell said he doesn't take for granted.
"It's clearly a sign of health for the organization," Farrell said. "You know guys in this stage of their career with multiple options, contractually you're not going to be able to acquire these type of players. So to have them in house, it is a luxury without question."
De La Rosa is the latest option Farrell has turned to. He was acquired from the Dodgers last season as part of the trade that sent Adrian Gonzalez, Josh Beckett and Carl Crawford to Los Angeles.
De La Rosa was briefly called up earlier this season, but entered Saturday's game waiting to make his first professional appearance with the Red Sox.
Due to his previous Major League pitching experience with the Dodgers -- including 10 starts -- De La Rosa was expected to be a player that the Red Sox could expect in the big leagues rather quickly.
But coming off Tommy John surgery in 2011, the right-hander has been inconsistent at times, compiling a 4.23 ERA over 20 starts at Pawtucket.
Farrell said De La Rosa might have felt a little discouraged to see so many of his teammates get a call to the Majors before him.
"I think it's probably human nature," the manager said. "Here's a guy that's pitched in the big leagues already. He's coming off a surgery, sees a number of guys that might have gone past him or get the call before he did, and I wouldn't say it would be uncommon that someone might feel that way. This recall isn't about feelings. Let's make that first and foremost clear. This is a guy that's got tremendous stuff that fills a need that we have right now."
Drew back in rhythm after struggling coming off DL
BOSTON -- After a stint on the disabled list, Stephen Drew finally seems to have found his swing.
The Red Sox shortstop has five hits over his last three games and entered Saturday batting .360 since July 27.
Normally these numbers wouldn't be enough to turn any heads, but Drew struggled mightily right after he came off the DL on July 20, collecting just one hit in his first 15 at-bats.
The turnaround isn't much of a surprise to those who know Drew. As Red Sox manager John Farrell explained, Drew relies on timing and rhythm more than most to be successful at the plate. An extended layoff can throw that timing out of whack, but with more consistent at-bats, Drew's production has picked up.
"He looks much more confident at the plate," Farrell said. "There's more authority to his swing. And as we've seen a couple of times that he's missed some time on the DL, as he gets those at-bats, he's so much a timing hitter and a rhythm hitter. Yeah, he's seeing the ball pretty good right now."
Drew clubbed a two-run home run against his former team, the D-backs, on Friday night. It was his third homer in the last seven games after hitting just five up to that point.
"I feel good," Drew said. "The balls are falling where I'm hitting them. Before, I was hitting lineouts. So it's a good feeling when you're hitting the ball and things are going your way."
• Catcher David Ross, who has been sidelined with a concussion, took batting practice on Saturday. If Ross' next checkup goes well, Farrell said he hopes the catcher can play in a rehab game by the end of next week.
• Franklin Morales (left pectoral strain) is scheduled to throw about 35 pitches for Pawtucket on Saturday, no matter how many innings that takes. Farrell wants to stretch out Morales before he can return to the Red Sox.
