Kevin Towers was not at Chase Field this past weekend because the D-backs' general manager was keeping an eye on the future.

The D-backs hold the third and seventh picks in the 2011 First-Year Player Draft in June, and Towers spent a couple of days checking out some of the country's top prospects, including high school fireballer Dylan Bundy and Rice third baseman Anthony Rendon.

"I usually go out in April and May," Towers said about scouting amateurs. "I doubt I'll see more than 10 players, but I certainly want to see the guys in the mix for [picks] three and seven. That's a significant amount of money, and I think the GM's eyes should at least be on the guys you're looking at."
