The Orioles signed Willis during spring training shortly after he was released by the Phillies and initially planned on using him as a situational left-handed reliever. Willis made just three relief appearances, pitching to a 4.91 ERA before he was abruptly placed on the minor-league restricted list after leaving the team.
He worked his way back through extended spring training games, but made just one start for the Tides — on Thursday — lasting just 2 2/3 innings and allowing four runs on six hits.
