New York Mets left-hander Johan Santana stopped throwing off a mound 10 days ago after "soreness" in his surgically repaired left shoulder surfaced when he increased the intensity of his delivery, general manager Sandy Alderson said Monday. Alderson said Santana has resumed long-tossing on flat ground and hoped to return to a mound later this week. Santana is working back from Sept. 14 surgery to repair a torn anterior capsule in his left shoulder. Alderson said the Mets will be prudent with Santana this season. After all, the left-hander is owed $24 million next season and $25.5 million in 2013. The Mets have a $25 million team option for 2014 that otherwise requires a $5.5 million buyout.
