What is interesting is that they were teammates last fall in the Arizona Fall League with the Scottsdale Scorpions. Not surprisingly, they have mutual admiration.
"Mike Trout is a great ball player, a five-tool guy who knows how to play the game really well," Harper said in an interview last month. "He is doing a great job and to be able to play next to a guy like that was a great experience for me."
Trout, before the Angels' weekend series with the Colorado Rockies at Coors Field, expressed similar feelings about Harper.
"It was fun playing with him, and he's a great kid who went out there playing hard and aggressive every day," Trout said.
"He has everything you need in a ballplayer, and he is getting the opportunity like me, and he is taking full advantage of it. I am happy for him."
Despite the inevitable comparisons, Angels general manager Jerry Dipoto said the 6-foot-1, 210-pound Trout and the 6-3, 215-pound Harper are different kinds of players - and not just because Harper bats lefthanded and Trout hits righthanded.
"Both are exceptionally gifted young players with different skill sets," Dipoto said.
"Bryce is more of a middle-of-the-order power banger type who is likely to wind up at a corner position.
"Mike is a middle-of-the-field pure athlete who has a significant run tool that most people in the game don't have.
"I don't know if they are comparable players, but they are comparable talents."
