The Royals announced they have lost left-handed reliever Gabe Speier to the Seattle Mariners on waivers. The 27-year-old had a 3.83 ERA and 4.23 FIP with 7.9 strikeouts-per-nine innings in 40 innings over parts of the last four seasons with the Royals. This year he had a career-high in innings pitched in the big leagues, making 17 appearances with a 2.33 ERA in 19 1⁄3 innings, although he had a reverse split with lefties hitting him better than right-handers.
Speier was originally drafted by the Red Sox in 2013, and has played in the Tigers, Braves, and Diamondbacks organizations before joining the Royals.
