Surprise, Ariz. ? Aramis Ramirez hit a two-run homer for the Chicago Cubs, but the Kansas City Royals overcame a shaky outing by Darrell May in a 6-5 win Tuesday.

May, who already has a spot in the rotation, gave up three runs in three innings, including Ramirez’s shot with two outs in the first.

He allowed another run in the third when he walked Alex Gonzalez and gave up a double to Derrek Lee.

Pitching coach John Cumberland said he was not concerned about May, who had a 9.26 ERA in five exhibition outings last year. May has been bothered by groin injuries in all three of his spring trainings with the Royals.

“He’s invariably a slow starter,” Cumberland said. “It just takes him a little longer. We just need to keep him healthy. Once it starts counting on April 5, he’ll be there. You want him to get better as he goes along and he will.”

Right-hander Shawn Camp, a non-roster invitee, worked a flawless ninth for the save. Camp has drawn attention by allowing just one hit in three innings in three relief appearances.

Mike Tonis homered in the sixth with Rick Short aboard off Juan Pena to put the Royals ahead for good.

Todd Hollandsworth and Calvin Murray each hit a solo home run for the Cubs in the fourth off Scott Sullivan.

D.J. Carrasco earned the win, working out of a bases-loaded jam in the sixth when Fernando Lunar grounded into an inning-ending double play.

Kansas City's Scott Sullivan holds his head after allowing two home runs in the fourth inning. The Royals rallied to beat the Cubs, 6-5, Tuesday at Billy Parker Stadium in Surprise, Ariz.

Cubs reliever LaTroy Hawkins walked country music singer Garth Brooks in the eighth. Brooks, who was hitting for Short, drew the largest applause of the day from the 7,016 fans at Surprise Stadium.

Kansas City center fielder Carlos Beltran was scratched from the lineup because of a sore right elbow and likely will be out a few days.

Beltran injured the arm in the fifth inning Monday, while diving back to first base on an attempted pickoff throw by San Francisco pitcher Dustin Hermanson.

“When I saw the ball get by the first baseman, I was trying to get back up and rolled over my wrist,” Beltran said. “I felt something in my forearm. I was feeling it all the way (running) to third base.”
