Diamondbacks starter Zac Gallen was impressive his last time out, giving up one earned run and striking out 10 Giants in seven innings.

The Mariners and Diamondbacks are frequent trade partners and the two could join forces again to bring Zac Gallen to Seattle at the deadline.

The Arizona Diamondbacks won game two of their four-game series with the San Francisco Giants on Tuesday by a score of 8-2. Zac Gallen delivered his best start in nearly a month, and his offense belted four homers, offering him plenty of run support. The Diamondbacks improve to 43-42, and the Giants fall to 45-41.
