SAN DIEGO -- Season-ending shoulder surgery for San Diego Padres star shortstop Fernando Tatis Jr. is "on the table" if his condition does not improve enough over the next 10 days, according manager Jayce Tingler.
The Padres placed Tatis on the 10-day injured list Saturday, a day after he partially dislocated his left shoulder for the third time this season.
The Padres announced the move prior to their 5-3 loss to the Colorado Rockies. Tingler said after the game that Tatis would be evaluated in 10 days.
San Diego also placed right-hander Chris Paddack on the IL with an oblique injury.
Tatis, the National League's starting shortstop in the All-Star Game, was injured Friday night while sliding awkwardly into third base in the first inning against the Rockies. He was in pain as he was led off the field by Tingler and a trainer.
Tingler said Tatis was "a little bit more sore than maybe some of them we've had in the past."
The Padres, who are in third place in the NL West and in control of the second wild-card spot, are keeping their fingers crossed that the electrifying 22-year-old Tatis will return in 10 days.
Tatis leads the NL with 31 home runs. He's hitting .292 with 70 RBIs.
