The Mariners and Rangers may see which team makes the postseason here. The teams close out their regular seasons by playing seven of the final 10 games against one another, beginning with Friday's opener of a three-game series at the Rangers. The Mariners (84-68) and Rangers (84-68) trail the American League West-leading Houston Astros (85-68) by a half-game in the division race. Both teams are also competing with the Toronto Blue Jays (85-67 entering Thursday) for the final two AL wild-card spots. Rookie right-hander Bryce Miller (8-5, 3.88 ERA) will start the opener for the Mariners. Miller has a 4.58 ERA away from Seattle, and we think the Rangers get to him today. Dane Dunning is even worse in his home ballpark, with a 6.61 ERA and 1.90 WHIP. We see runs here on Friday and will side with the over.
