San Diego Padres reliever Yuki Matsui will miss the World Baseball Classic after suffering a groin strain that also casts doubt on his availability for the team's season opener. The injury prevents the left-hander from representing Japan in the international tournament.

Matsui's absence creates a significant gap in Japan's pitching staff for the WBC, where he was expected to be a key contributor. The 26-year-old reliever has been an important part of the Padres' bullpen since joining the organization, posting a 3.09 ERA in 70 appearances last season.

The groin injury couldn't come at a worse time for both Matsui and the Padres, who will need to adjust their bullpen plans heading into the regular season. San Diego's coaching staff will likely monitor his recovery closely to determine his readiness for Opening Day.
