Surprise, Ariz. ? Ambiorix Burgos is slated to fill in as the Kansas City Royals’ closer while Mike MacDougal starts the season on the disabled list.

The 21-year-old Burgos, who has two major-league saves, is still getting used to the job.

After entering a tie game in the seventh inning, Burgos gave up a leadoff triple to Brian Anderson and threw a wild pitch that allowed the go-ahead run to score in a 6-5 loss to the Chicago White Sox on Monday.

“I like his stuff, but he’s still learning how to pitch,” Royals manager Buddy Bell said.

Bobby Jenks worked out of a bases-loaded jam in the eighth for Chicago, coaxing Wilson Valdez to ground into an inning-ending double play.

Anderson had a two-run single, and Tadahito Iguchi added an RBI double in a five-run second for the White Sox. All the runs came off Danny Tamayo, a right-hander from Notre Dame who was brought over from minor-league camp to pitch.

Tamayo retired only five of his 13 batters, yielding five hits and two walks.

Doug Mientkiewicz went 3-for-3 with a three-run homer off Brandon McCarthy and four RBIs for the Royals. Mientkiewicz also scored in the first on Angel Berroa’s two-out single.

Kansas City second baseman Mark Grudzielanek can't come up with a ground ball hit by Chicago's Ryan Sweeney. The White Sox rallied for a 6-5 victory over the Royals on Monday in Surprise, Ariz.

Hideo Nomo, who signed a minor-league contract with the White Sox, started and gave up two runs and three hits in two innings, striking out two.

Left-hander Jimmy Gobble, who is out of minor-league options and is trying to earn a spot in the Royals’ bullpen, worked a perfect inning, striking out one, to lower his earned-run average to 2.57.

Right fielder Reggie Sanders was scratched from the Royals’ lineup because of tightness in an elbow.
