Surprise, Ariz. ? Mat Latos lost the strike zone, then was at a loss for words.

A 14-game winner last year with San Diego, Latos walked four in the first inning and Padres pitchers combined for 10 walks in a 4-3 loss Tuesday to the Kansas City Royals.

Latos threw only 15 of 34 pitches for strikes and got only four outs in his spring training debut. He walked four of his first five batters but didn’t allow a run because Mike Aviles was caught stealing for the second out of the inning.

Latos retired Mitch Maier on a popup to strand the bases loaded.

“I’m trying to think the best possible word right now,” Latos said after his outing. “There are no words that I can say how I feel about this outing, seriously. I felt fine as bad as I looked out there. I was missing by a lot. I threw it everywhere, but in the strike zone.”

Clint Robinson, who won the 2010 Texas League triple crown with a .335 average, 29 homers and 98 RBIs, tripled and doubled in his first two at-bats. He drove in two runs and scored another on Maier’s double.

Mike Moustakas’ two-out single in the eighth scored Lorenzo Cain, who had doubled with the winning run. Cain went 2-for-2 and made a lead-saving catch to end the ninth with two on.
