SCOTTSDALE, Ariz. (AP) - His general manager has described Adam Eaton as the quintessential leadoff hitter - scrappy, fast, a daring threat to cause havoc on the bases.

The Arizona Diamondbacks rookie has quite an opportunity this spring, and he intends to make the most of it.

Eaton knows the pressure is on, but as he put it, ``if you can't deal with pressure by now you shouldn't be in this game.''

Eaton's feisty attitude stems, he says, from his diminutive size - he's 5-foot-8 - and the battles that have ensued to prove that a short guy can play the game at a high level.

He calls it ``that Napoleon syndrome'' and he's counting on it to carry him through a long major league career.
