One year after pitching a no-hitter, right-hander Chris Heston was traded from the San Francisco Giants to the Seattle Mariners on Wednesday for a player to be named. The Giants did not have a spot for the 28-year-old in their rotation featuring Madison Bumgarner, Johnny Cueto, Jeff Samardzija, Matt Moore and Matt Cain. Seattle's need for additional rotation depth made the Mariners a perfect partner.
