to Class AAA Omaha on an outright assignment.
Neither move was unexpected.
Both players were designated for assignment on Nov. 20 when the Royals cleared space on their 40-man roster to protect four players who otherwise would have been eligible for selection next month in the Rule 5 Draft.
Falu, 30, is now a free agent who is permitted to sign with any club. He spent 11 seasons in the Royals’ system following his selection in the 21st round of the 2003 draft but managed just 95 big-league plate appearances over the last two seasons.
The move with Arguelles, 23, comes after he cleared waivers and provides the Royals with another opportunity to salvage their January 2010 investment of $6.9 million over five years following his defection from Cuba.
Arguelles also received a major-league contract as part of his original deal, but he underwent shoulder surgery later in 2010 and rarely pitched to expectations. He was a combined 1-9 last season with a 5.73 ERA in 28 games with three minor-league clubs.
Players who clear waivers are required to accept an outright assignment once in their career. Thereafter, they can choose to become a free agent.
