The Royals recalled Bowlan from Triple-A Omaha on Saturday.
Bowlan rejoins the big-league bullpen after three weeks at Omaha, filling the spot vacated by Bailey Falter (bicep), who was placed on the 15-day injured list. Bowlan has a 4.73 ERA and a 24:11 K:BB across 26.2 innings for the Royals this season.
