KANSAS CITY -- Another veteran pitcher was added to the Royals' spring bullpen mix when the club announced the signing of right-hander Jon Rauch to a Minor League contract on Thursday. He received an invitation to the Major League training camp.

Rauch, a sizable entry at 6-foot-11 and 290 pounds, is considered to be the tallest pitcher in Major League history. He has 11 years of Major League experience with eight different clubs. He's 35 and last pitched in the Majors for the Marlins, appearing in 15 games before being released last May 22 with a 1-2 record and a 7.56 ERA.

He also pitched in the Orioles organization in 2013, posting a 2.89 ERA in 10 appearances at Triple-A Norfolk.

In his 11 big league seasons, Rauch appeared in 556 games (11 starts) with a 43-40 record, 62 saves and a 3.90 ERA for the Nationals, Twins, D-backs, White Sox, Mets, Blue Jays, Expos and Marlins.

His last full season was 2012, when he worked 73 games for the Mets, going 3-7 with four saves. He opened the season with 11 consecutive scoreless outings covering 10 innings. The same year, Rauch lost seven straight decisions in a 20-game span.

He had a career-high 21 saves for the Twins in 2010 after closer Joe Nathan had surgery.

The Royals, well-known for their youth-oriented bullpen, earlier this month signed 40-year-old reliever Guillermo Mota to a Minor League deal.
