SEATTLE, Wash. – The Seattle Mariners open the 2023 season at T-Mobile Park on Thursday, March 30 against the Cleveland Guardians. Tickets for the game are sold out, but there are still tickets for the remaining games in the Opening Homestand.

All gates will open at 5:10pm, pregame presentations will begin at 6:30pm and the game will begin at 7:10pm.  All fans are encouraged to arrive early. Each fan attending Opening Day will receive a 2023 season magnetic schedule upon arrival.

Pregame Telecast

The pregame telecast begins at 6:00pm and will be carried live on ROOT SPORTS.

Ceremonial First Pitch

Throwing out the ceremonial first pitch will be a collection of Seattle All-Stars.

Run Around the Bases

During the pregame ceremony, the traditional ceremonial run around the bases by a Make-A-Wish® child will feature 5-year-old Coleman, who is from Bainbridge Island, WA. In 2019, Coleman was diagnosed with bilateral retinoblastoma, a rare eye cancer, and he is now in remission. Coleman visited the Mariners at Spring Training and spent the day with the team, joining the team meeting, participating in batting practice and more. This is the 24th consecutive year a Make-A-Wish child has performed the ceremonial first run around the bases on Mariners Opening Day. Since becoming the Mariners naming rights partner in 2019, T-Mobile has donated $10,000 to Make-A-Wish every Opening Day and is proud to do so again this year.

Awards Presentation

Prior to first pitch, the Mariners will do a special presentation on-field honoring Julio Rodríguez for winning AL Rookie of the Year and his first Silver Slugger award.
