Sunday: The Twins have officially announced Graterol’s promotion. The club has also selected the contract of speedy outfielder Ian Miller. Additionally, the club has recalled left-hander Devin Smeltzer and right-handers Zack Littell and Kohl Stewart from Triple-A Rochester. Further, the Twins activated catcher Willians Astudillo and outfielder LaMonte Wade, Jr. from respective 10-day injured list stints. To clear 40-man roster space, the club recalled minor-league right-hander Sean Poppen and transferred him to the 60-day injured list. He’d been on the minor-league IL with a right elbow contusion.
Saturday: Top Minnesota Twins pitching prospect Brusdar Graterol will see September innings at Target Field, per LaVelle E. Neal III of the Star Tribune.
A shoulder impingement took out a chunk of Graterol’s season, but since returning he’s been promoted and relegated to the bullpen in Triple-A. He has just 4 appearances thus far as he prepares for a similar role with the big league club after rosters expand. Minnesota plans for Graterol to return to a starting capacity for 2020.
Graterol will need to be added to the 40-man roster whenever he gets the call-up, though that won’t happen until sometime after September 1. Contrary to the belief of many on Twitter, not being on the 40-man roster by tomorrow does not preclude Graterol from postseason play. The Twins can petition the MLB for Graterol’s eligibility as an injury replacement for a current 40-man rosteree, such as Nick Gordon or Sean Poppen, offers MLB.com’s Dan Hayes (via Twitter).
The bigger question will be answered by Graterol’s performance on the field. The newly-21-year-old flamethrower has just 4 appearances in Triple-A and only 10 career appearances out of the pen. That the Twins are considering such a rapid promotion for Graterol in the dead heat of a pennant race speaks to their belief in his overall ability and makeup. He certainly comes with the pedigree to be an impact performer. Major prospect outlets have him as a consensus top prospect, the overall #55 prospect by MLB.com, #33 by Baseball America, and #69 by Fangraphs.
