Belisle will open the season in the Nationals' bullpen, MLB.com's William Ladson reports.

EDGE Analysis

Belisle entered camp as a non-roster invitee, but he will exit it as a member of the Nationals' bullpen. Expect Belisle, who posted a 2.67 ERA but a 1.46 WHIP in 34 games with the Cardinals last season, to work as a middle reliever with his new club.
