Harper went 2-for-3 with an RBI to extend his hitting streak to 16 games and Trout -- MLB.com's No. 1 prospect, knocked in another run Friday as the Scottsdale Scorpions scored three times in the third inning and held on to beat the Phoenix Desert Dogs, 3-2.
The Scorpions got all the runs they needed in the scheduled seven-inning contest on RBI singles from Trout and Brandon Crawford (Giants) and a double by Harper. Phillies farmhand Cody Overbeck started the third with a double and came home on Trout's line drive to right that dropped in front of A's prospect Grant Green. Joe Panik, the Giants' top pick in the 2011 Draft, singled off Tyson Ross to move Trout into scoring position for Crawford, who blooped a single into left.
Harper, the No. 1 overall selection in the 2010 Draft, followed with a two-out double to right off reliever Tyler Sturdevant (Indians) for a 3-0 lead.
Harper, batting .321, also singled leading off the sixth. He has six homers and 25 RBIs over 21 games in his second AFL stint.
Trout, who reached the Majors this summer with the Angels, hasn't fared quite as well. He's batting .253 and entered Friday's game hitting .194 in his last 10 starts. The RBI was only his fourth in 23 games.
Red Sox right-hander Jeremy Kehrt (2-0) made his ninth appearance and second start, holding the Desert Dogs to a run on two hits and three walks over two innings. He struck out one.
Ross (1-3), an A's prospect, was charged with three runs on five hits over 2 1/3 innings. He did not walk or strike out a batter. Indians lefty T.J. McFarland looked sharp in relief, throwing four scoreless frames to close out the game for Phoenix.
The Dogs scored in the second when Yan Gomes drew a one-out walk and came home on fellow Blue Jays prospect Anthony Gose's single to center. Jake Diekman worked out of trouble in the seventh after Ryan Ortiz's run-scoring single made it 3-2. The Phillies prospect struck out Dusty Coleman (A's) and Gose before retiring Green -- the A's No. 1 prospect who hit a grand slam Thursday -- for the final out.
