Heston was 1-1 last season, holding a 10.

80 ERA and tossing three strikeouts in four games for the Giants. In 2015, he went 12-11 with a 3.95 ERA and 141 strikeouts in 31 starts. He also went 2-0, with a 4.29 ERA, in 92.1 minor league innings last season. Heston also threw a no-hitter in 2015 against the New York Mets.

To clear 40-man spot for Mark Melancon, #SFGiants might move Chris Heston in small-scale trade. Could get done tonight.

San Jose Mercury News Giants reporter Daniel Brown said the team might make the move to clear a roster spot for the recently acquired Mark Melancon.
