Kline announced Wednesday via his personal Instagram account that he has retired from professional baseball.

EDGE Analysis

A second-round pick of the Orioles in 2012, Kline had a slow climb through the Baltimore system due to a series of arm injuries, but he finally reached the big leagues in 2019. He ended up making 37 appearances for Baltimore across the past two seasons, posting a 5.48 ERA in 46 innings. After being outrighted off the 40-man roster in October, Kline likely would have had to settle for a minor-league deal this winter if he wanted to keep his career going, but the 29-year-old apparently determined he was better off stepping away from the game.

Kline refused his outright assignment to Triple-A Norfolk on Friday and was released by the Orioles, Nathan Ruiz of The Baltimore Sun reports.

EDGE Analysis

The 29-year-old elected free agency rather than heading back to Triple-A. Kline appeared in three games this season and gave up one run with seven strikeouts and three walks over five innings. He had a 5.93 ERA and 1.54 WHIP in a larger sample size (41 innings) during 2019.

Kline was outrighted to Triple-A Norfolk on Thursday, Roch Kubatko of MASNSports.com reports.

EDGE Analysis

Kline was shuffled between the major-league roster and the alternate training site in 2020, and he'll be cast off the 40-man roster heading into the offseason. The right-hander made three relief appearances during the abbreviated 2020 season, recording a 1.80 ERA and seven strikeouts over five innings.

The Orioles recalled Kline from their alternate training site Wednesday.

EDGE Analysis

He'll rejoin the Baltimore bullpen as a replacement for Evan Phillips (elbow), who was placed on the 10-day injured list in a corresponding move. Over 35 career relief appearances spanning 42.2 innings, Kline owns a 5.70 ERA.

Kline was optioned to Baltimore's alternate training site following Game 1 of Thursday's doubleheader against the Rays.

EDGE Analysis

Kline was called up for the first game of the day, but he'll head right back down after failing to make an appearance. He's pitched in one game this season, tossing 1.2 scoreless frames while allowing one hit and fanning three.

Kline was recalled from the alternate training site Thursday.

EDGE Analysis

Kline made his major-league debut in early September and will rejoin the Orioles with less than two weeks left in the regular season. The 28-year-old should fill a low-leverage role out of the bullpen.

Kline was optioned to the team's alternate site Monday.

EDGE Analysis

Kline was recalled for the team's weekend series, but is being optioned so that Carson Fulmer can be activated. Kline appeared in one game, throwing 1.2 scoreless innings while striking out three.

Kline's contract was purchased by the Orioles on Friday.

EDGE Analysis

The 28-year-old threw 41 innings in his debut season last year, posting a 5.93 ERA and 1.54 WHIP. He was expected to serve as the 29th man for Friday's doubleheader against the Yankees, but the placement of Alex Cobb (undisclosed) on the injured list led to Kline receiving a traditional promotion.

Kline will be a part of the Orioles' 60-man player pool this season.

EDGE Analysis

Kline was outrighted off the 40-man roster back in February, but he is now eligible to pitch in the majors this season. He logged a 5.93 ERA in 41 MLB innings last season.

Kline cleared waivers and was outrighted to Triple-A Norfolk on Wednesday, Dan Connolly of The Athletic reports.

EDGE Analysis

Kline debuted as a 27-year-old last season, posting an unimpressive 5.93 ERA in 41 innings of work. Neither his 18.6 percent strikeout rate nor his 10.4 percent walk rate were particularly good.
