Padres’ manager Craig Stammen told reporters on Friday that Yuki Matsui could end up missing the upcoming World Baseball Classic as he’s battling left groin tightness.

Matsui suffered the injury during a live batting practice session on Thursday. They’ll take it day-by-day and see how he’s feeling, but it sounds like he may be unable to compete in the Classic. As of now though, his availability for the start of the regular season isn’t in doubt.
