Top prospect Trevor Bauer retired all six batters he faced in his spring training debut Saturday and an Arizona Diamondbacks split-squad and the Colorado Rockies tied 1-1 in 10 innings.
Bauer, the third overall pick in last year's draft out of UCLA, struck out two. He threw seven pitches in the first inning, striking out Dexter Fowler looking and getting Marco Scutaro and Carlos Gonzalez to ground out. Troy Tulowitzki and Michael Cuddyer grounded out and Tyler Colvin struck out in the second inning against the 21-year-old right-hander.
Rockies left-hander Drew Pomeranz struck out two, walked one and allowed a hit in two scoreless innings.
Colorado catcher Ramon Hernandez had two singles in two at-bats. His second single tied the score 1-all in the fourth inning.
