Parnell was released by the White Sox on Monday, Daryl Van Schouwen of the Chicago Sun-Times reports.

EDGE Analysis

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 signed a minor-league contract with the White Sox on Monday, Ken Rosenthal of Fox Sports reports.

EDGE Analysis

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 exercised the opt-out clause in his Royals minor-league deal Friday to become a free agent, Ken Rosenthal of Fox Sports reports.

EDGE Analysis

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.

Parnell was reassigned to the Royals' minor-league camp Monday, MLB.com's Jeffrey Flanagan reports.

EDGE Analysis

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.

Parnell received a spring training invite from the Royals on Saturday, Jeffrey Flanagan of MLB.com reports.

EDGE Analysis

Parnell hasn't shown major league effectiveness since receiving Tommy John surgery in April 2014, so this is strictly a reclamation project for the Royals. He has shown top-shelf bullpen stuff in the past, it's just a question if he will ever be able to find that stuff again.

Parnell has cleared waivers and been released by the Tigers.

EDGE Analysis

Parnell's performance was unimpressive in the MLB this season, as he allowed four runs over just 5.1 innings (six games). However, his career ERA and WHIP in the majors are 3.82 and 1.44, respectively. While these aren't phenomenal marks, a team may be interested in Parnell to add depth to their bullpen, whether it be with the big club or a minor league affiliate.

Parnell was designated for assignment Thursday.

EDGE Analysis

The Tigers opted to call up outfielder Alex Presley from Triple-A after Tyler Collins sustained a bruised knee Wednesday night, so a move to free up a roster spot was necessary, and Parnell will be the casualty. The 31-year-old hasn't pitched in more than a month and has allowed four earned runs on seven hits across 5.1 major league innings on the season. He'll be subject to waivers but will likely land at Triple-A Toledo.

Parnell was recalled from Triple-A Toledo on Wednesday.

EDGE Analysis

Since getting demoted back on June 14, Parnell has allowed just one run over nine appearances, bringing his minor league ERA down to 3.07 following some early-season struggles. He'll now head back to Detroit to provide support in middle relief.

Parnell was optioned to Triple-A Toledo on Tuesday.

EDGE Analysis

Parnell has struggled in limited action since his contract was purchased by the Tigers at the start of the month, allowing four hits and three earned runs across 3.2 innings of relief work. The 31-year-old will now head back to Triple-A, where he holds a 3.98 ERA in 20.1 innings on the season. He'll be replaced in the Detroit bullpen by Buck Farmer, who was officially recalled Tuesday in a corresponding move.

Parnell had his contract purchased Wednesday by the Tigers, Anthony Fenech reports.

EDGE Analysis

Parnell had spent the previous eight seasons with the Mets, posting a 3.78 career ERA as a reliever. However, he had a career-worst 6.38 ERA in 2015 through 24 innings of relief, leading him to sign a minor league deal with the Tigers. After putting up a 3.98 ERA in 21 appearances for Triple-A Toledo, he will now get a shot to contribute at the big league level again with Tigers' reliever Warwick Saupold being placed on the 15-day DL.
