Johan Santana is long-tossing, according to a team spokesman.
The last time Santana threw, however, is unknown.
The spokesman noted that Santana did not do anything on Sunday, but wouldn't specify an exact date when asked the last time Santana threw.
Santana stopped throwing off a mound on June 2 after he began experiencing "soreness" in his surgically repaired left shoulder as he increased the intensity of his delivery.
Santana had resumed long-tossing on float ground, and hoped to return to a mound by week’s end. He is trying to come back from Sept. 14 surgery to repair a torn anterior capsule in his left shoulder.
General manager Sandy Alderson has said the Mets will be prudent with Santana this season.
The 32-year-old is due $24 million next season and $25.5 million in 2013. The Mets have a $25 million team option for 2014, which includes a $5.5 million buyout, if they out to go in that direction.
Alderson had no timetable for Santana’s return Monday. He did note that Santana has not started what would be considered the beginning of spring training program that pitchers begin in mid-February to prepare for Opening Day.
Manager Terry Collins hopes that Santana can return in “July, maybe August or September.”
“I’ve talked to Johan,” Collins said Monday. “To be honest, he’ll decide. We can put whatever plan we want. Ultimately, when he feels right, he’ll pitch."
Santana went 11-9 last season with a 2.98 ERA. For his career, he's 133-69 with a 3.10 ERA.
