Villareal signed a minor league contract with the Reds on Saturday that includes an invite to major league spring training, Mark Sheldon of MLB.com reports.
Villarreal posted a 3.42 ERA with a 1.38 WHIP over 50.0 innings as a reliever with the Reds last season. He was non-tendered at the beginning of the offseason but he'll be brought back on a minor league deal that does include an invite to big league spring training. Given the Reds' bullpen overhaul, Villarreal could have an outside shot at landing a low-leverage role in the bullpen.
