Kirby&#8217;s strikeout rate is just above league average at 23.3%, but what&#8217;s more impressive is his ability to avoid walking batters. Since he broke into the majors, nobody in baseball has been able to limit walks the way Kirby does. His 3.1% walk rate is the lowest amongst all starters, and is almost 5% under the league average.\u00a0Since his debut, only Chris Martin owns a lower walk rate as a qualified reliever.<\/p>\n<p>The Mariners are getting Kirby back at a good time, as Logan Gilbert and <a href=\"https:\/\/lastwordonsports.com\/baseball\/2025\/03\/01\/up-coming-pitcher-2025\/\" target=\"_self\">Bryce Miller<\/a> are both currently on the 15-day injured list. The club currently sits at the top of the A.L. West at 28-20, and will kick off a four-game series against the second-place Astros tonight.
