Guardians To Sign Shawn Armstrong

The Guardians and right-hander Shawn Armstrong have agreed to a deal, reports Jeff Passan of ESPN. The ISE Baseball client will be guaranteed $5.5MM on a one-year pact with a mutual option. The Guards have a full 40-man roster and will need to make a corresponding move to make this deal official.

Armstrong returns to his original organization. He was drafted by Cleveland back in 2011 and pitched for them in the majors from 2015 to 2017. In the almost decade since then, he has spent time with the Mariners, Orioles, Rays, Marlins, Cardinals, Cubs and Rangers.

Despite that nomadic journey, his performance has been fairly steady in some respects. His earned run average has wobbled from year to year, but that’s not unusual for relief pitchers, who pitch a small number of innings annually and can have ERA swings from a few bad games. From 2019 to 2025, Armstrong tossed at least 36 innings in each full season with at least 52 frames in five out of six. His strikeout rate finished between 22% and 27% in each of those. His walk rate has finished below 9.2% in six straight seasons.

Put it all together and Armstrong has thrown 363 1/3 innings since the start of 2019 with a 3.96 ERA, 24.6% strikeout rate and 7.8% walk rate. Despite that fairly solid trajectory, he settled for a modest $1.25MM deal with the Rangers for the 2025 season.

Texas was surely pleased with that investment. Armstrong averaged about 94 miles per hour on both his four-seamer and sinker while also mixing in a cutter, slider and curveball. He tossed 74 innings on the year with a 2.31 ERA, 26.1% strikeout rate and 7% walk rate. His .196 batting average on balls in play and 76.3% strand rate were unsustainably fortunate but his 3.07 FIP and 3.36 SIERA suggest he would have fared well even with neutral luck. He saved nine games and registered 12 holds for the Rangers.

Armstrong has parlayed that into a new deal worth more than four times his last one, the biggest payday of the 35-year-old’s career. The Guardians had a strong bullpen in 2025, as their collective 3.44 ERA was third in the majors behind only the Padres and Red Sox. They are down one key member, as Emmanuel Clase is under investigation for a gambling scandal and may never pitch in the majors again.

The Guards don’t usually have tons of money to throw around but have been busy augmenting their bullpen with minor moves. They have signed Colin Holderman and Connor Brogdon to big league deals. They acquired Justin Bruihl from the Blue Jays and selected Peyton Pallette from the White Sox in the Rule 5 draft. Those new arms will add to a group which includes incumbents Cade Smith, Hunter Gaddis and others.
