Bauer hurled two scoreless innings against the Padres in Scottsdale on March 14, striking out three batters and allowing one hit. The young pitcher's performance left Black impressed.
"I liked him, his arm works good and he's athletic," Black said. "I like his leanness and his quick twitch to his body in his delivery. I enjoy that style of pitching, I'm curious to see him live in a Major League game."
Bauer has drawn comparisons to two-time National League Cy Young Award winner Tim Lincecum for his unusual delivery and approach.
"Just by looking at him, you can draw some similarities," Black said about Bauer's likeness to Lincecum. "The body type, the turn on the rubber and the arm slot."
