Andrew Heaney ranks in the bottom half of the league in xBA, average exit velocity, barrel rate and hard-hit rate. His 4.12 xERA indicates negative regression is looming, as well. Seattle has hit .250 BA and .479 SLG with a .352 wOBA in 161 combined career ABs vs him.

George Kirby is 5-0 with a 1.08 ERA in seven career appearances (41.2 IP) against Texas. He held the Rangers to one run (zero earned) on three hits with six Ks in a six-frame win earlier this year (June 15). Kirby has been a bit inconsistent recently but I favor him and the Mariners' bullpen (4th in WHIP and 9th in ERA) in this pitching matchup against a Texas lineup that's without star Corey Seager and ranks 26th in wRC+ (86), 26th in wOBA (.289) and 28th in hard-hit percentage (29.9%) in the last 30 days.
