Each of the Seattle Mariners (84-71, 41-33 home) and Houston Astros (85-71, 46-29 away) could find themselves in the MLB postseason. There’s also a solid likelihood that one of these clubs will be going home when the regular season concludes on Oct. 1.

Javier Was Solid Until September

Javier is 0-2 in four starts and has surrendered 10 earned runs in 20 innings of work for a 4.50 ERA. He’s 2-3 since a five-game win streak from May 10-June 3 that left Javier 7-1 on the season. He’s failed to get through the fifth inning in four of his past nine starts.
Javier has faced the Mariners once this season, working seven innings. He didn’t figure in the decision and finished with a 3.86 ERA. But he’s 3-1 with a 2.45 ERA in eight career appearances against Seattle.

An AL all-star, Mariners right-hander George Kirby displays the best strikeouts/walks ratio (8.94) and fewest walks per nine innings (0.9) of any MLB pitcher this season. He’s issued just two free passes over his past 50 innings on the bump.
With a 6-3 verdict over the Oakland Athletics in his last start on Sept. 20, Kirby ended a 45-day winless skid. But his most recent win at T-Mobile Park was a 5-0 shutout of the Minnesota Twins on July 20.
