The left-hander will work with Mike Herbst, the Mets' Minor League strength and conditioning coach, who has been brought to New York for the week. Santana will continue to play long-toss until he is ready to throw off a mound, which manager Terry Collins believes will be sometime toward the middle of next week.
"After that we're hoping that he's back," Collins said.
Santana is scheduled to make a start on Aug. 8 or Aug. 9 as long as everything checks out and he doesn't suffer any setbacks.
Over his three most recent starts, Santana surrendered 19 earned runs in 12 2/3 innings. After he lasted just three innings and surrendered six earned runs to the Dodgers on Friday, he was placed on the 15-day disabled list with a sprained ankle.
