Mariners' Chris Heston: Traded to Mariners

Heston (oblique) was traded to the Mariners on Wednesday for a player to be named later, FOX Sports' Jon Morosi reports.

Analysis:

Considering the Giants may have left Heston off the 40-man roster to accommodate Mark Melancon, it is not surprising that it only required a PTBNL for the Mariners to net the 28-year-old righty. Heston may be behind Nate Karns and Ariel Miranda in the pecking order for the fourth and fifth starter spots in Seattle, but he has a better chance of eventually joining that rotation than if he had remained in the Giants' system. He has a career 4.04 FIP, 1.37 WHIP and 148 strikeouts in 188 big league innings, mostly working as a starter. An oblique injury ended his 2016 season, but he should be recovered by the time spring training rolls around.
