The Royals obtained Carroll from the Twins for cash or a player to be named on Aug. 11. He got into just 14 games for KC, going just 4-for-36 (.111), but his last hit -- a double off the White Sox's Chris Sale on Sept. 27 -- was the 1,000th of his career.
Carroll, 39, also played 59 games for the Twins and finished the season at .211 with nine doubles and 11 RBIs. He's also played for the Expos/Nationals, Rockies, Indians and Nationals during his 12-year Major League career.
Arguelles, 23, who had a groin injury and had shoulder issues in the past, was scheduled to pitch in an Arizona Fall League game on Friday. He was limited to 28 games (13 starts) for three Minor League teams this season. Most of his time was spent with Double-A Northwest Arkansas, and he was 1-8 with a 5.93 ERA in 25 games.
