Maya for in for Marquis (traded to Zona)
Diamondbacks acquired RHP Jason Marquis from the Nationals for INF Zachary Walters. Marquis should slide nicely into the Arizona starting rotation and will try to help the Diamondbacks make up some ground in the Wild Card standings. He's registered a 3.95 ERA and 71/39 K/BB ratio through 120 2/3 inning this season. Walters, a 21-year-old shortstop, was drafted in the ninth round back in 2009 and has posted a strong .861 OPS in 97 games this year at the Single-A level.
