From Nick Cafardo’s Sunday notes column in the Boston Globe:
Mark Prior, RHP, free agent – He will likely attempt one more comeback. He spent some of last season with the Yankees, his rebuilt arm holding up well and getting his velocity into the low 90s. But Prior, who was the Stephen Strasburg of his day, has a new problem. After many weeks of trying to figure out what was wrong with the lower half of his body, he had surgery for a sports hernia, but the problem wasn’t completely corrected. He is working out near his home in San Diego, trying to figure it out. He will likely work out for teams as early as March.
Prior, the No. 2 overall pick in the 2001 MLB Amateur Draft, registered a promising 2.25 ERA, 0.75 WHIP and 15/4 K/BB ratio across 12 minor league innings last year. He hasn’t appeared in a major league game since the 2006 season, but he could score a spring training invitation if he’s healthy and throwing well before spring training concludes.
