Royals add Humber via Minors deal

Right-hander was part of Mets-Twins swap for Santana

The Royals have agreed to terms with right-handed pitcher Philip Humber on a Minor League contract for the 2010 season, the club announced Tuesday. He becomes the eighth non-roster pitcher to receive an invitation to Kansas City's Major League spring camp.

Humber, 26, has spent the past two seasons in the Twins organization and was part of the five-player trade that sent pitcher Johan Santana to the Mets.

For his career, Humber is 0-0 with a 6.07 ERA in 18 career Major League appearances for the Mets (2006-07) and Twins (2008-09). He went 7-9 with a 5.34 ERA in 23 games (22 starts) for Triple-A Rochester in 2009.

Humber was the Mets' first-round selection in the 2004 First-Year Player Draft, taken third overall.

Currently playing winter ball with Leones de Ponce, Humber is 2-3 with a 4.19 ERA in seven games (six starts). He's allowed 34 hits while striking out 29 and walking 12 over 34 1/3 innings.
