The Minnesota Twins assigned eight players to Salt River Rafters for the 2018 Arizona Fall League. The Rafters were managed by the Twins 2018 AA Chattanooga manager and newly hired first base coach Tommy Watkins. The team also included prospects from the Arizona Diamondbacks, Colorado Rockies, Miami Marlins, and Washington Nationals.
The Rafters won the East Division title with a 16-14 record. The team dominated early but lost six of the final regular season games. The Minnesota contingent had mixed results overall. As a group, the hitters lacked power and the while the pitchers put up a 4-2 record, they struggled to keep runners off base.
