it depends if Hughes has no trade rights, per The Cub Reporter Outright Release Waivers Submitted by Arizona Phil on Sun, 09/02/2012 - 1:38am Outright Release Waivers are irrevocable and cannot be withdrawn once they are requested. While a player claimed off Outright Assignment Waivers costs $20,000 (or $25,000 for a Rule 5 or Draft-Excluded player), a club can claim a player off Outright Release Waivers for the minuscule sum of $1. However, a club that claims a player off Release Waivers is responsible for paying 100% of the player's remaining salary, whereas if the same club waits until the player clears Release Waivers, the club can sign the player for the MLB minimum salary (or prorated portion of the MLB minimum salary), with the player's former club responsible for the balance. A player who is claimed off Outright Release Waivers has the option to decline the assignment and become a free-agent (he has up to five days to decide). For most players, refusing an Outright Release waiver claim means the player's contract is terminated with no severance and his former club owes him nothing (same as an Article XX-D minor league FA who refuses an Outright Assignment), but for a player with "no trade" rights who refuses an Outright Release waiver claim, the player is owed his full salary for the balance of the contract, same as if he had not been claimed. http://www.thecubreporter.com/outright-release-waivers
