Vazquez (elbow) has been throwing to bases at Boston's spring-training facility in Fort Myers (Fla.), the Boston Globe reports. "He's probably at about 90 percent," manager John Farrell said. "But it's there. You can see that. He'll only get better."

Prior to undergoing Tommy John surgery, Vazquez was known for his arm strength and his ability to control the running game. As such, the Red Sox are closely monitoring his velocity and accuracy. On Friday, Vazquez showed off the accuracy in what was another productive day in his return from the injury. Despite what has been an encouraging rehab, Vazquez is expected to start the season at Triple-A Pawtucket where he can get some game experience before joining the major-league roster.
