Jeremy Pena went 4-for-6 with two homers and four RBIs and Yordan Alvarez added a three-run shot as Houston routed Oakland to enter the regular-season finale tied with Texas, holding the tiebreaker. Today's decisive result was not yet available as of this report.

Houston and Texas are separated by a half-game after Thursday's action, with the division being decided on the season's final weekend. Houston holds the head-to-head season-series tiebreaker advantage (9-4) even though Texas has a half-game edge in the loss column.

Houston lost 6-5 in 10 innings to Seattle after leading 4-0 in the third, with Josh Naylor delivering the winning single. Both the Astros and Rangers lost Tuesday, so the AL West remains a dead-even tie entering the final week; Houston holds the tiebreaker after winning 9 of 13 meetings with Texas this year.

Houston placed Cristian Javier (groin strain) and Brice Matthews (knee inflammation) on the injured list this week, timing the moves so both could potentially return for a Division Series while missing only a Wild Card Series. Jake Meyers was formally moved to the 60-day injured list, ending his season.

Yordan Alvarez had an RBI single (his 100th RBI of the season) and an 8th-inning 2-run homer (his 41st, tying Junior Caminero for the AL lead); he also leads the AL in batting average at .314, keeping him in the Triple Crown conversation. Christian Walker hit his 26th homer (200th of his career); Isaac Paredes added a solo shot. Cristian Javier left after two innings with right groin tightness; Miguel Ullola earned his first MLB win.
