Starters who were on the opposite ends of the headline spectrum at the trade deadline will meet in Phoenix when Arizona and Cincinnati play the rubber game a three-game series on Sunday.

Reds right-hander Trevor Bauer (10-12, 4.55 ERA) was among the group of high-profile pitchers who changed teams at the July 31 deadline, but he has been up-and-down in his eight starts since being acquired from Cleveland for Yasiel Puig.

Arizona's Zac Gallen (3-5) is closing in on a major league rookie record after being acquired from Miami for shortstop prospect Jazz Chisholm at the deadline -- a deal that flew well below the radar on a day in which the Diamondbacks traded Zack Greinke and also acquired Mike Leake.
