Christian Walker hits walk-off three-run homer as Astros beat Mariners in 10 innings

Houston opened the contest with a strong start, pulling ahead 5-2 by the second inning. Seattle answered back, erasing the deficit and eventually leading 7-6 in the top of the 10th after a Victor Robles triple and a Brock Rodden sacrifice fly. Closer Andrés Muñoz surrendered RBI singles to Isaac Paredes and Daulton Varsho, tying the game at 7-7 with two outs.

Christian Walker then launched a three-run walk-off homer, securing a 10-7 win for the Astros. The triumph widens Houston's margin in the closely contested AL West, while the Mariners fall further behind. The result also follows the Astros' recent sweep of the Texas Rangers and sets up series against the Angels and Athletics.
