KANSAS CITY -- A day after losing left-handed pitcher Dusty Hughes to the Twins on waivers, the Royals added another lefty to their Spring Training arsenal.

Brandon Sisk, who pitched last season for their Northwest Arkansas club, on Thursday was invited to the Major League camp. He's the 24th non-roster player, including 14 pitchers, to receive an invitation.

Sisk, 25, had a 4-6 record, nine saves and a 4.46 ERA in 40 relief outings for the Texas League champion Naturals with 63 strikeouts in 68 2/3 innings. He also pitched 10 games for Surprise in the Arizona Fall League and posted a 2.51 ERA and held batters to a .167 average.

He'll be the 12th left-hander in camp, joining Bruce Chen, Jeff Francis, Everett Teaford, Noel Arguelles, Tim Collins, Danny Duffy, Chris Dwyer, Blaine Hardy, John Lamb, Mike Montgomery and Will Smith.

Pitchers and catchers are to report officially on Feb. 14 at the Surprise complex but many are expected to check in early.
