Impact Kirby's rocky first spring outing notwithstanding, Servais has nothing but praise and elevated expectations for his precocious right-hander. The 25-year-old took full advantage of the knowledge base of the older arms on the Mariners' staff once he arrived at the big-league level in May, learning an arm-care routine and also working up to throwing six different pitches. Kirby is now experimenting with a splitter this spring in order to expand his arsenal even further as he looks to build on the 8-5 record, 3.39 ERA, 1.21 WHIP and 24.5 percent strikeout rate he generated across 25 starts in 2022.
