Anthony Ranaudo pitched six solid innings in his major league debut and Dustin Pedroia drove in two runs as Boston snapped a three-game losing streak. Derek Jeter led off the eighth with a shot over the Green Monster to pull the Yankees within 4-3, but they failed to drive in Mark Teixeira for the tying run after his ground-rule double with one out. Boston got to Chris Capuano (1-2) in the third when Brock Holt hit a one-out triple down the right-field line, then scored when Pedroia followed with a drive over Jacoby Ellsbury's head in center. After Beltran's 13th homer of the season cut the lead to 2-1, the Red Sox got an RBI single from David Ross in the fourth and added an insurance run in the seventh when Pedroia singled home Mookie Betts, who led off with a single and advanced on a sacrifice. Doctors will evaluate Masahiro Tanaka on Monday, three weeks after he was given a platelet-rich plasma injection in his torn ulnar collateral ligament as an alternative to surgery. Webster went 5 1-3 innings last week against the Rays, allowing two runs and five hits and getting the victory as Boston snapped a five-game losing streak. Ellsbury appeared to have an extra-base hit in the eighth on a drive to his former territory in the center-field triangle, but was robbed on a lunging catch by Mookie Betts — an infielder who's getting a chance in the outfield.
