Diamondbacks trade for Zac Gallen from Marlins

The Arizona Diamondbacks acquired starting pitcher Zac Gallen from the Miami Marlins for infielder Jazz Chisholm.

What It Means:

Gallen made huge improvements in the minors this season and shined for the Marlins after making his big league debut on June 20. Turning 24 in a few days, the right-hander could stick around in the Diamondbacks' rotation for years to come.

Gallen is 1-3 in seven starts. He owns a 2.72 ERA and 1.18 WHIP with 43 strikeouts and 18 walks over 36 1/3 innings.
