CHICAGO -- Chris Heston was hopeful a move to a new organization could give his career a jolt. It hasn't worked out that way.
The former Giant was designated for assignment on Wednesday by the Mariners, who earlier acquired an outfielder from the Astros and needed the roster spot. Heston was traded to Seattle at the winter meetings for a player to be named later. The Giants have not yet picked that player off a list the teams agreed to.
Heston had a 3.95 ERA as a starter for the Giants in 2015 and threw a no-hitter at Citi Field, but he had trouble transitioning to relief the next season and dealt with an injury in Triple-A. Needing a roster spot in December, the Giants traded him.
Heston started Sunday for Seattle and gave up six earned runs in three innings. He allowed five earned in two innings in his previous appearance.
