Parnell was signed to a minor-league pact in the beginning of June, but the right-hander got shelled. In 13.1 innings of work, he allowed 17 earned runs on 25 hits. His MLB experience may give him notoriety on the free agent market, but his best days appear to be behind him.

Parnell began the season in the Royals organization, but he exercised his opt-out clause after failing to garner a callup during the first two months of the season. He appeared 15 times with Kansas City's Triple-A affiliate, producing a 4.71 ERA and a 1.57 WHIP. His control was lackluster at best (5.6 BB/9), so he'll likely act as an organizational depth piece unless he can shore up his performance.

Parnell posted a 4.71 ERA over 21 innings with Triple-A Omaha. The 32-year-old right-hander could latch on with another organization this season but probably will top out as a depth pitcher.

Injury woes have derailed a once-promising career for Parnell, who spent most of last season with Triple-A Toledo in the Tigers organization. After submitting an uninspiring 3.95 ERA and 1.42 WHIP in 43.1 innings with Toledo, Parnell will need to show dramatic improvement for Triple-A Omaha before the Royals consider adding him to the 40-man roster.
