The Seattle Mariners' pitching staff is experiencing a renaissance, showcasing unparalleled depth and resilience in the 2024 season. Remarkably, four Mariners pitchers surpassed 30 starts, with seven different arms taking the mound throughout the year. While left-handed reliever Jhonathan Diaz contributed with a start, it was Emerson Hancock's 12 starts that stood out, showcasing his potential as the team's No. 6 starter. However, as the 2025 season approaches, maintaining this health will be critical.

Hancock has shown commitment to refining his arsenal, experimenting with pitch grips and techniques during the offseason. In a spring training debut against the Arizona Diamondbacks, he exhibited promise by striking out two batters and maintaining a strike rate of 82%. Hancock expressed a desire to improve his command and consistency on the mound, noting that the offseason was spent fine-tuning his cutter and sweeper. With a challenging season behind him, he finished with a 4.75 ERA and aims for a more impactful 2025, likely starting with the Triple-A Tacoma Rainiers.

After a long offseason, the Seattle Mariners return to action in the Cactus League, kicking off their spring training against the San Diego Padres. The Mariners will feature left-hander Jhonathan Diaz, who is vying for a spot in the rotation after a solid Triple-A season. Other key players like Julio Rodriguez and JP Crawford will also take the field, indicating the team's intent to build on last year's near-playoff run. With Donovan Solano delayed due to visa issues and Jorge Polanco recovering from knee surgery, the roster remains competitive as players vie for limited spots.

The Mariners finished last season with an 85-77 record, just missing out on the playoffs. The Padres, conversely, had a strong performance and made it to the postseason, highlighting the competitive landscape ahead. Vancouver fans will be keen to see whether Diaz can solidify his position and how the rest of the roster performs in the run-up to the season.

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.
