Johan Santana stopped throwing 10 days ago after suffering soreness in his surgically-repaired left shoulder, general manager Sandy Alderson told reporters before Monday's game in Pittsburgh.
Santana hasn't seen a doctor, but he hasn't thrown off the mound since it started hurting him, but has thrown long toss. He could return to the mound this week.
Alderson went out of his way, apparently, not to call it a setback.
"He's progressing extremely well," Alderson told reporters, including Andy McCullough of the Star-Ledger. "But once the intensity cranks up, it wouldn't be surprising that there would be some soreness."
Santana had surgery to repair a torn anterior capsule in his left shoulder last September.
Alderson said when Santana starts throwing off the mound again, it will be like the beginning of spring training for him, so he'd still need about six weeks to get ready -- and that's without any more setbacks.
Santana is still owed $24 million next season and $25.5 million in 2013 and can buy him out of a $25 million option for 2014 for $5.5 million. It's unlikely the team will do anything to rush him, likely looking at this season as a sunk cost and hope to get some value out of him the next two years.For more baseball news, rumors and analysis, follow @cbssportsmlb on Twitter or subscribe to the RSS feed.
