As the Mariners gear up for Opening Day, one question looms large: Who will fill the No. 5 starter spot? With Bryce Miller working his way back from a left oblique inflammation, this decision has become crucial for a team that otherwise enjoyed a smooth Spring Training.
Kade Anderson, Seattle's No. 2 prospect according to MLB Pipeline, showed promise but was never a real contender for the role. His reassignment to Minors camp confirms that the battle is now between Emerson Hancock and J.T. Criswell, with the decision likely impacting the fifth game of the season against the Yankees at T-Mobile Park.
Mariners manager Dan Wilson acknowledged the importance of this choice, stating, “These are the things we're going to have to look at over the next three, four or five days.” With the season approaching, these decisions are becoming urgent.
Initially, Seattle's rotation depth seemed thin, especially after Logan Evans, fresh off a strong rookie campaign, underwent Tommy John surgery in January. However, the performances of the Nos. 6-8 spots have been encouraging, providing a bit more stability.
Hancock has impressed with his fastball, averaging 95.5 mph and peaking at 97.4 mph. His ability to generate 17 strikeouts from 44 batters (a 38.6% rate) is notable, especially with just one walk and one homer allowed.
His offspeed pitches, particularly sliders and sweepers, have been effective, inducing whiffs 44% of the time. Hancock noted, “It just blends really well with the arsenal.”
Hancock's previous experience filling this role gives him an edge, having stepped in for George Kirby and Bryan Woo in past seasons. Meanwhile, Criswell, who is out of Minor League options, adds intrigue to the mix. His experience as a long reliever could be vital, especially in April when starters' workloads are closely monitored.
Criswell, who started 18 games for Boston in 2024, boasts a four-pitch mix, with a sinker and changeup that excel at generating depth. His sweeper and cutter add versatility, contributing to his career 3.54 ERA over 21 starts. “I don't feel like it changes really a ton for me,” Criswell said about his preparation.
As for Anderson, his potential is undeniable, but his time will come later. Manager Wilson emphasized the value of professional experience, suggesting Anderson’s moment will arrive once he’s more seasoned.
As the Mariners make their final decisions, the battle for the No. 5 starter spot remains one of the most intriguing storylines heading into the season.
