11:57am: Sugano is guaranteed $5.1MM, reports ESPN’s Jeff Passan.
11:19am: The Rockies and veteran right-hander Tomoyuki Sugano are in agreement on a one-year, major league contract, reports Thomas Harding of MLB.com. MassLive’s Chris Cotillo reported not long before Sugano’s signing that the Rockies were still working to add some veteran rotation help. Sugano is represented by the VC Sports Group.

Sugano, 36, was a star in Japan prior to last season’s major league debut — one of the most durable and successful starting pitchers of the current generation in Nippon Professional Baseball. He contemplated a move to MLB earlier in his career but opted to remain with the Yomiuri Giants on a four-year, $40MM deal in the 2020-21 offseason rather than make the jump to North America.
He finally opted to commit to an MLB opportunity last offseason, signing a one-year, $13MM deal with the Orioles. He was one of several one-year additions to the Baltimore rotation, and Sugano panned out better than either Charlie Morton or Kyle Gibson did after signing a short-term deal with Baltimore.
It wasn’t a dominant debut effort by any means, but Sugano made 30 starts and piled up 157 innings with a 4.64 earned run average. His 5.3% walk rate was excellent, but the right-hander’s 15.1% strikeout rate was among the lowest in Major League Baseball. That lack of missed bats and pedestrian velocity on his fastballs (92.7 mph average four-seamer, 92.9 mph average sinker) led to too many barrels and far too many home runs. Sugano was tagged for 33 round-trippers — most in the American League and third-most in all of MLB — or an average of 1.89 homers per nine frames.
Certainly, that home run susceptibility is cause for some concern as Sugano signs on to play his home games at Coors Field. Then again, the Rockies entered the offseason in dire need of rotation help and are always going to have a hard time selling free agent starters on pitching at elevation. They managed to sway Michael Lorenzen earlier in the offseason and will now add Sugano, at the very least giving the rotation a pair of veteran options to eat innings and take some pressure off some still-developing young arms.
Sugano joins a rotation slated to include Lorenzen, Kyle Freeland and Ryan Feltner. Top prospect Chase Dollander, the No. 9 pick from the 2023 draft, was hit hard as a rookie in 2025 but probably has the inside track on the No. 5 spot. Nearly all of his 2025 struggles came at Coors Field; he posted a 3.46 ERA, 22.4% strikeout rate and 11.3% walk rate on the road (compared to a 9.98 ERA at home). Other candidates for the fifth spot include Tanner Gordon, McCade Brown and Carson Palmquist, among others.
More to come.
