The Braves have acquired left-hander Ryan Rolison from the Rockies, according to announcements from both clubs. The Rockies, who designated Rolison for assignment yesterday, receive cash considerations in return. Atlanta’s 40-man roster count climbs to 38.
It’s a buy-low move for Atlanta. Rolison was a first-round pick back in 2018, getting selected 22nd overall by the Rockies. He signed with a bonus just north of $2.9MM. He was one of the club’s top prospects in the years after that draft selection but hasn’t yet delivered on his potential.
His trajectory to the majors was thrown off in a few ways. The minor leagues were canceled in 2020 on account of the pandemic. The next few years were curtailed by various injuries, most notably shoulder problems. He was capped at 71 2/3 minor league innings in 2021, missed the entire 2022 season, threw 11 frames in 2023 and then 46 1/3 innings in 2024. He had initially been a starter but has been mostly working out of the bullpen more recently.
In 2025, he finally made it to the show but the results weren’t impressive. He tossed 42 1/3 innings for Colorado this year, allowing 33 earned runs for a 7.02 ERA. His 13% strikeout rate and 10.4% walk rate were both subpar figures.
If one wanted to look for signs of optimism, his minor league numbers are worth a glance. He tossed 29 2/3 Triple-A innings this year, in the hitter-friendly Pacific Coast League. In that environment, he had a 3.34 ERA, 25.2% strikeout rate, 7.1% walk rate and 48.8% ground ball rate.
Rolison got nudged off the roster in Colorado but Atlanta had some space and will give him a shot. He still has an option year remaining, so his new club can keep him in the minors as left-handed depth, if they so choose. His service time count is at two years and 114 days, meaning he still hasn’t qualified for arbitration and can be controlled for four seasons. That could extend to five if he ends up spending a large amount of time on optional assignment.
Atlanta seems to have a fondness for getting relievers out of Colorado. In recent years, they have grabbed guys like Pierce Johnson, Brad Hand and Tyler Kinley to bolster their bullpen group. Now they’ll take a shot on Rolison. His overall track record isn’t great but he’s a former first-rounder who is optionable and controllable, while the cash they gave up is presumably minimal. They also won’t be relying on him as he’s probably seventh or eighth on the lefty relief depth chart behind Aaron Bummer, Dylan Lee, Dylan Dodd, José Suarez, Joey Wentz, Hayden Harris and/or Josh Walker.
