It's a special night at T-Mobile Park as the Mariners honor one of the greatest pitchers in franchise history. The Big Unit, Randy Johnson, will have his number retired in a pregame ceremony, and Emerson Hancock will take the mound to carry the torch—just as Logan Evans did during Ichiro's number retirement ceremony last year.

On the other side, the Royals counter with their reigning Organizational Pitcher of the Month, Seth Lugo. After last night's surprising slugfest, expect runs to be scarce today—a fitting tribute to Johnson's dominant legacy. First pitch is set for 5:22 PT, with the number retirement ceremony beginning at 6:30.

In a late lineup change, Cal Raleigh has been scratched without explanation. Mitch Garver will handle catching duties and bat eighth. Cole Young moves up to the five-hole, followed by Canzone, Raley, Garver, and Rivas. And yes, if you ask "since when does Cole Young bat fifth?" in the game thread, consider yourself warned—shin-kicking is legally permitted.

In other roster news, the Mariners made a quiet paper move, calling up lefty Josh Simpson to cover Matt Brash's spot on the 15-day IL while righty Nick Davila arrives from Arkansas. Simpson's stint was brief—barely enough to get to know him—but the team is shuffling arms to stay fresh.

Catch all the action on Mariners TV with Aaron Goldsmith, Dave Valle, and Angie Mentink, or tune into 710 AM Seattle Sports with Rick Rizzs and Gary Hill Jr. It's a night to remember, both for the Big Unit's legacy and the young arms trying to follow in his footsteps.
