SEATTLE (AP) — Rookie Mike Montgomery tossed a four-hitter against the team that drafted him, Dustin Ackley singled, doubled and homered for his first three-hit game of the season and the Seattle Mariners beat the Kansas City Royals 7-0 on Tuesday night.

Montgomery (2-2) became the second Mariners pitcher this season to toss a complete game, joining Felix Hernandez, and he became the 10th rookie in Seattle history to toss a complete game. Montgomery retired 17 straight batters at one point, striking out a career-high 10 and allowing only two base runners after the second inning.

Montgomery was originally drafted by the Royals, but was eventually traded to Tampa Bay before landing in Seattle via trade before the start of this season. He walked none and escaped a bases loaded jam in the first inning before overpowering Kansas City the rest of the way.
