NATIONAL HARBOR, Md. — Faced with a crowded depth chart and a need for a roster spot, the Giants shipped right-hander Chris Heston to Seattle on Wednesday night.
The Mariners announced the deal shortly after 7pm PT on Wednesday.
Heston, who made 31 starts and threw a no-hitter for the Giants in 2015, would have been designated for assignment had a deal not gotten done. The Giants will receive a player to be named later. The move clears a 40-man roster spot for closer Mark Melancon, who signed Monday.
Heston, 28, filled in after injuries to veterans in 2015 and posted a 3.95 ERA and 12 wins, one of which was a no-hitter in New York. He was a first-half savior for an unhealthy staff, going 9-5 with a 3.39 ERA in 18 starts before the All-Star break. The long season caught up to Heston down the stretch, and the Giants filled their rotation that December with free agents Johnny Cueto and Jeff Samardzija.
Heston made just four appearances in 2016 after being moved to the bullpen. It was a transition that didn't quite take, and he ended up back in the minors, making 14 starts for the River Cats as he worked to regain some of the velocity that was lost when he dropped 15 pounds during offseason workouts. An oblique injury led to Heston being put on the 60-day DL in June and ultimately ended his season.
This represents a needed fresh start for Heston, who was hopelessly blocked in the Giants’ system. The Giants acquired Matt Moore at the deadline and Ty Blach and Matt Cain will compete for the final rotation spot. Veteran Albert Suarez and top pitching prospect Tyler Beede are among the starters who had jumped ahead of Heston. In Seattle, he joins a team in need of starting depth, and he should get a shot to return to a big league rotation.
