GLENDALE, Ariz. — Dodgers catcher Russell Martin is expected to miss opening day after an MRI exam revealed a pulled groin.
Martin first felt discomfort during a running drill a few days before the Dodgers' first spring game Friday. He started Friday's game against the White Sox and played five innings, even stealing a base.
"We don't know how long it's going to be," general manager Ned Colletti said Sunday in Mesa, where Los Angeles' spring game against a Cubs split squad was rained out. "It's four to six weeks right now but you know how that goes."
A.J. Ellis, who has 13 career major-league at-bats, will get the bulk of the catching duties with Martin out. The Dodgers also have veteran backup Brad Ausmus, who turns 41 in April.
On Sunday, Martin called his injury "a little strain" and said it wasn't a big deal. Moments later, manager Joe Torre said otherwise.
"We're going to send him back to L.A. to have another evaluation," Torre said. A team doctor "looked at the MRI and it's a groin pull. He played on it a couple of days thinking it was just spring training aches and pains."
Torre said Martin still can do strengthening exercises for his upper body and taking batting practice was a possibility.
