Spring training kicks off today with the Seattle Mariners facing the San Diego Padres at 12:10 p.m. MT in Peoria, Arizona. Mariners manager Dan Wilson confirmed that left-handed reliever Jhonathan Diaz will start the game, amidst a rotation strategy that allows core starters to ease into their rhythm over the early games. Diaz, who has had a tumultuous path in recent seasons, will look to establish himself in what appears to be a competitive bullpen. Last season, Diaz posted a 4.66 ERA with eight strikeouts over 9.2 innings.

With the team focusing on short outings for starters, several relief pitchers will have opportunities to prove themselves during camp. The Mariners are optimistic about their roster depth and the potential of emerging pitchers being integrated into the major league team. Moreover, there are notable future developments, including the mentorship role of Edgar Martinez for rising star Julio Rodriguez, which could bode well for the Mariners' offensive prospects.
