TUCSON—Luis Gonzalez got a long look at Justin Upton early in the Diamondbacks' spring training camp, when both spent several days in the same hitting group. Gonzalez' report sounded just like those of the scouts that have watched him for years: "I didn't hit balls that far when I was 18, and I still can't right now at 38," Gonzalez said. "As a veteran, you kind of blow it off when you hear about (a hyped young hitter). It's pretty eye-opening watching him swing the bat. The first thing you think of is, 'No way he's 18 years old.' "
