Several top prospects in what many consider to be the most talent-rich organization in baseball -- the Royals -- got into the game as Kansas City topped the San Diego Padres, 4-3, in the Cactus League on Tuesday.

Aaron Crow and Mike Montgomery, two of the Royals many touted pitching prospects, each had a turn on the mound. Neither was overmatched against Major League hitters.

Crow, a first-rounder from the 2009 Draft, got the ball in the third inning. He issued a one-out walk and then three straight singles, allowing a run to score, before inducing a popup and getting a strikeout. The right-hander worked a 1-2-3 fourth.

Montgomery, the Royals' first-round choice in 2008, took over in the fifth. Padres prospect Jarrett Hoffpauir led off the frame with a walk, but Montgomery got Chase Headley to dribble into a double play. After a second walk, the southpaw got Nick Hundley to ground out.

Jeremy Jeffress, acquired from the Brewers for Zack Greinke in December, also pitched an inning for the Royals, allowing a run on a pair of hits and picking up a strikeout.

Clint Robinson, who won the Texas League Triple-Crown with the Northwest Arkansas Naturals last summer, tripled and doubled for Kansas City.

Mike Moustakas and Eric Hosmer came into the game off the bench, and Moustakas knocked in the winning run with an eighth-inning single.

Yet another KC prospect, Lorenzo Cain was 2-for-2 with a run scored. Playing center field, he made a fantastic catch with one out in the ninth, then doubled off the Padres' Luis Durango at second base to end the game.

San Diego also put a pair of its pitching prospects on display.

Simon Castro was dinged up in the fifth inning, surrendering a pair of runs on three hits and a walk. Anthony Bass, who was 8-8 with a 3.33 ERA between Class A Advanced and Triple-A ball last year, struck out two and allowed a hit and a walk over one inning's work.
