Royals sent LHP Noel Arguelles outright to Triple-A Omaha. Arguelles cleared waivers after being designated for assignment one week ago. The 23-year-old had a lot of hype after signing with the Royals back in 2010, but he has failed to live up to expectations. He had a 5.73 ERA this year in the minors.

Royals activated LHP Noel Arguelles from the 60-day disabled list. The move was made so that Arguelles can pitch in the Arizona Fall League. The 23-year-old Cuban defector posted a 5.93 ERA across 71 1/3 frames this season while missing a big chunk of time with a groin ailment.

Royals transferred LHP Noel Arguelles to the 60-day disabled list. The 23-year-old Cuban defector has managed to move himself completely off the prospect radar over the last two seasons, going 5-22 with a 6.23 ERA in 190 2/3 innings at Double-A Northwest Arkansas. Arguelles is still young, but the Royals may decide to do without him on the 40-man roster next year. Kansas City signed the southpaw to an ill-fated five-year, $7 million contract in 2010.

Royals optioned LHP Noel Arguelles from Double-A Northwest Arkansas. The 23-year-old Cuban defector has failed to live up to expectations to this point in his Royals career. He posted a 6.41 ERA over 25 starts at the Double-A level in 2012, and clearly needs much more seasoning before he's even a consideration for the big league roster.
