From the NY Daily News Blog section:

Here's what GM Omar Minaya said today about each:

On Gomez:

What strikes you about him?

"You’re talking about a player that has great physical ability. He’s got speed. He’s got an arm. He’s got youth. He’s aggressive. He plays the game in a style that I like to think the Mets are about – we’re about stealing bases and aggressive baseball."

Do you see him as a leadoff hitter?

"I don’t know. I couldn’t tell you he’s going to be that. Just because he has speed, that doesn’t mean he’s a leadoff hitter. He has power potential, too. He can be so many different things because of his ability. As long as he’s in the lineup, I don’t care where he hits."

On Martinez:

Is the fact he's doing it at 18 more impressive?

"You’re talking about a kid that would be a senior in high school right now. Maybe even a junior. To be able to do what he’s doing – his hitting ability, just how he handles himself as a person, maturity, he’s a special player."

Will he start in Double-A?

"We’ll see how he goes. He’ll try to make the Double-A team. We weren’t afraid to challenge him last year. We won’t be afraid to challenge him this year."

Will he and Gomez mostly play center field in the minors this year, or would you move them to the corners in preparation for their likely role in the majors?

"It doesn’t matter. They might rotate. They might play center field. We did that with Juan Gonzalez and Sammy Sosa. They played center field and then we switched them around."
