Bauer, drafted by the D-backs out of UCLA last year, is scheduled to square off against San Diego's Andrew Cashner on Tuesday.
"A lot of guys are naturally gifted and other guys have to train and throw," Black said. "Ultimately, it's the survival of the fittest, and if a guy is able to throw a lot, I think it is awesome. Now, there is a component of being able to step back and rest your arm when you need to, but I'm a proponent of throwing."
Bauer's routine starts about 120 minutes before each start and includes a series of yoga-like exercises and long tosses that can reach 350 feet.
"Last year, he was at the Pauley Pavilion watching games and this year he is in the big leagues," Black said. "He must be doing something right."
