Dominic Leone – 11.1 IP, 6.35 ERA, 5.37 FIP, -0.2 WAR

Hey look, another 2014 mainstay with an almost completely unbelievable ERA! Leone missed the team out of Spring Training, and while it looked like an odd-man-out situation at the time, it turned out to be performance-driven. The M’s traded him for a guy who was been one of the worst players on earth for the last month-plus. Remember how awesome Leone was just a year ago? Grade: F

Yoervis Medina – 12 IP, 3.00 ERA, 4.41 FIP, -0.1 WAR

Medina had the results but not the peripherals, which led first to a demotion and then to a trade for the guy who would eventually be traded along with Dom Leone for the team’s worst player to date. Medina allowed a bunch of home runs but was otherwise more or less okay. The Mariners really, really don’t like when their relievers allow a bunch of home runs. Relievers in Seattle who do that get traded, even if they’re alright aside from that. Grade: C-

David Rollins – 4.1 IP, 12.46 ERA, 4.92 FIP, -0.1 WAR

A nice rule five pickup, Rollins tore it up all spring before getting hit with a steroids suspension right before he was about to be announced as a member of the opening day roster. He just came off the restricted list and has been hot trash in his first taste of the majors. If he improves even the tiniest bit the M’s will probably keep him all year. If he sucks even worse then he’ll go back to Houston and really become somebody, probably. Grade: F
