Sox sign pair of top international pitching prospects

BOSTON -- In moves that could have significant impact on the franchise in the coming years, the Red Sox officially announced the signings of two highly touted international pitching prospects Friday -- right-handers Anderson Espinoza and Christopher Acosta.

Espinoza was ranked the top international pitcher by MLB.com, and Espinoza was ranked second.

In all, the Sox signed eight international prospects, a group that also included right-handers Nicolo Clemente, Jhosmar Cortez, Junior Espinoza and Roniel Raudes; lefty Luis Colmenares; and third baseman Elwin Tejeda.

All eight players are working out at the Red Sox' Dominican academy in El Toro.

Craig to start rehab assignment Monday

BOSTON -- Red Sox outfielder Allen Craig wil be back in game action Monday, when he starts a Minor League rehab assignment. The outfielder arrived to Fenway Park on Aug. 1, and played that night, only to sprain his left foot running the bases.

The outfielder arrived to Fenway Park on Aug. 1, and played that night, only to sprain his left foot running the bases.

Craig will play for Triple-A Pawtucket. At the most, he will probably play three days in the Minors. He could return to the Red Sox by the end of the four-game series against the Angels or the beginning of next weekend's three-game set vs. Seattle.

"We're hopeful that he goes out on a rehab assignment early this coming week, possibly as early as Monday," said Red Sox manager John Farrell before Friday's game. "He came out of [Thursday's] work of full BP, and some running in the outfield in good fashion. And he'll go through three more days of work prior to heading out."

The Red Sox will also get another player back in the coming days in backup catcher David Ross, who got hurt the same night as Craig, suffering a rupture of the right plantar fascia.

Ross could be activated as early as Sunday, the first day he is eligible.

"But we've still got to get some steps accomplished with David. He's set to catch a bullpen [session] today," said Farrell. "He started to do a little bit more running [Thursday] and came out of it feeling OK. He's making adequate progress as well."

Worth noting

• Farrell spoke to the Cumberland, R.I., Little League team on Friday, hours before they played their first game in the Little League World Series.

"From what I understand, each year the New England representative ends up having a conversation with the guy in my seat," said Farrell. "It's happened for a number of years. I remember [former Red Sox manager Terry Francona] having the same conversations as well. Today, they were energetic, great questions, and they're really pumped up about playing tonight."

• A followup that Red Sox right fielder Shane Victorino had following back surgery revealed no red flags, and he should be able to make a standard recovery, which would have him back in plenty of time for Spring Training.

"You know, he's following a pretty standard protocol right now," Farrell said. "And that's just gradual activity of walking, no real functional movements of any kind yet. The followup checkup did not have anything alarming. Like we said, he's following the normal protocol."
