General Manager Kevin Towers said shortstop prospect Didi Gregorius, acquired in December in the Trevor Bauer trade, has been shut down for roughly the past month with elbow problems and might have to start the season on the disabled list.

Towers said Gregorius’ elbow didn’t feel good after a long-toss session in January, at which point he traveled to Arizona to be evaluated by team physician Dr. Michael Lee.

“Dr. Lee said it was nothing serious and we decided to err on the side of being cautious,” Towers said. “Dr. Lee felt it would be best to take four weeks to shut him down, with no swinging a bat or throwing, and then start ramping him up.”
