St. Louis Third baseman Fernando Tatis, on the disabled list since April 29 with a torn groin, is closer to rejoining the St. Louis Cardinals.
Tatis will begin a four-day rehab stint with Memphis on Monday, and will reclaim his job on Friday if all goes well.
"This is good news," Tatis said Sunday.
The Cardinals had considered activating Tatis without a rehab, but he experienced some soreness after hitting under simulated game conditions twice last week. The biggest reason they didn't activate him Monday is the Cardinals play a three-game series at Cincinnati on artificial turf.
"Playing him on turf just doesn't make sense," general manager Walt Jocketty said. "He hasn't faced live pitching in two months, so it's kind of tough to come right back. We've got to kind of ease him into it."
Tatis is hitting .375, and he was leading the NL with 28 RBIs when he was injured on a fielding play.
The Cardinals, short on pitchers for their series finale against the Los Angeles Dodgers on Sunday, called up right-hander John Ambrose from Double-A Arkansas and optioned right-hander Gene Stechschulte to Triple-A Memphis.
The regulars also were a bit worn out, with Mark McGwire getting a day off. Jim Edmonds played first base instead of McGwire.
