The Rangers are 5-1 in their last six games vs. a left-handed starter, including 4-0 in their last four home games. They are 16-8 straight-up at home this season, including 12-5 (70.6%) as home favorites. They're also 11-5 in division games.
Texas' splits vs. left-handed pitchers: .293 BA/.370 OBP/.460 SLG/.830 OPS
Andrew Heaney: two earned runs in the last three starts combined (19.0 innings)

Seattle's splits vs. left-handed pitchers: .221 BA/.289 OBP/.381 SLG/.670 OPS
The Mariners are 1-7 in their last eight games vs. a starter with a WHIP of less than 1.15.

I am confident the Rangers are legit betting favorites and believe they're worth the squeeze at -141 juice Saturday!
