GOODYEAR, Ariz. (AP) Jesus Montero hit a grand slam, Michael Saunders homered among his three hits and the Seattle Mariners hammered Homer Bailey in a 16-0 rout of the Cincinnati Reds on Monday.
Saunders connected off Bailey, and Justin Smoak added two hits off the right-hander, driving in three runs. Montero's slam came off Wilken De La Rosa, one of two non-roster pitchers left in Reds camp.
Bailey was scheduled to pitch five innings but lasted only 3 1-3, allowing nine runs on nine hits and two walks. He struck out five.
Saunders also doubled, singled and scored three times from the leadoff spot.
Brandon Maurer continued to impress the Mariners. He gave up six hits and a walk in five innings, striking out seven. The 22-year-old is making a strong case to earn a spot in Seattle's starting rotation.
