SEATTLE, Wash. – It’s Opening Night in Seattle. Here’s everything you need to know about Game 1 of 162:

Brayan Bello is making his first career Opening Day start. The 24-year-old right-hander will face off against a fellow Dominican, 31-year-old Mariners starter Luis Castillo.

Jarren Duran LF / Rafael Devers 3B / Trevor Story SS / Triston Casas 1B / Tyler O’Neill RF / Masataka Yoshida DH / Ceddanne Rafaela CF / Enmanuel Valdez 2B / Connor Wong C

O’Neill has homered in each of his last four Opening Day games. Can he make it five?

This is one of the youngest Opening Day lineups in recent Per Sox history, with Bello and Casas (both 24) and Rafaela (23). According to the club’s media relations, the Sox have reached the postseason in each of the last five seasons in which they had at least three players younger than 25 starting on Opening Day: 2017, ’16, ’13, ’08, and ’88.

Brandon Crawford SS / Julio Rodríguez CF / Jorge Polanco 2B / Mitch Garver DH / Cal Raleigh C / Mitch Haniger RF / Dominic Canzone LF / Ty France 1B / Josh Rojas 3B

Raleigh was a thorn in Boston’s side last season. He hit two home runs in their May 15 contest at Fenway (off Tanner Houck and Brennan Bernardino), then homered twice off Nick Pivetta at Fenway on July 31 and took John Schreiber on Aug. 2.

Chris Martin and Kenley Jansen are “full go,” Alex Cora said before the game.

The Red Sox broadcast is available on NESN, and the Mariners broadcast can be found on Root Sports. (Blackout restrictions may apply.)

The Red Sox and Mariners series continues with 9:40 p.m. ET games on Friday and Saturday, followed by a 4:10 p.m. ET series finale on Sunday.
