HOUSTON — Last time here, with some 25 family and friends in the stands, Mariners right-hander Bryce Miller pitched what might have been the best game of his professional career, twirling seven shutout innings of two-hit ball against Astros on Sept. 23, 2024. Miller is eager to get back on a mound — any mound — for his delayed season debut, but he’s especially thrilled that he gets to do it here, close to home. “It’s good to be back in Texas.

It’ll be good to see the family, to be able to have them here for the first one will be good and get back on track.” Miller will make his season debut Wednesday against the Astros, which also begins the Mariners’ experiment with a six-man starting staff that will last at least one turn through the rotation.…
