DENVER -- Colorado Rockies rookie shortstop Trevor Story could miss the rest of the season with a torn ligament in his left thumb.
An MRI on Monday revealed that Story suffered a torn ulnar collateral ligament while sliding into second base during Saturday's win over the Mets. He said Tuesday he hopes to have surgery "in the next few days" and that the typical rehab time is eight weeks.
The Rockies recalled infielder Rafael Ynoa from Triple-A Albuquerque.
Story was having a record year. He set a NL record for home runs by a rookie shortstop with 27 and was on pace to surpass Nomar Garciaparra's record of 30 set with Boston in 1997.
He hit two home runs in his major league debut on opening day, the first NL player to accomplish the feat, and was named the NL Rookie of the Month for April after connecting 10 times.
