Garton has a 1.59 ERA, 0.44 WHIP, .103 BAA and .141 wOBA allowed over 11.1 innings across 12 appearances since joining the Mariners on Sept. 1.
The right-hander was traded to Seattle from the Rays on Aug. 6 and struggled upon arriving at Triple-A Tacoma, posting a 6.00 ERA over 12 innings. However, Garton has turned it around at the big-league level. His performance has been a notable improvement over his only other major-league stint, when he generated a 4.35 ERA and 1.40 WHIP with the Rays over 37 appearances in 2016.
