Martinez excelled in his first appearance with the Philadelphia Phillies on Wednesday.
Not on the mound, which isn't ready for him yet.
Pedro, with the ink barely dry on his $1-million contract ($1.5 mil. with incentives), was on his game at an introductory press conference (VIDEO).
Martinez called himself "stupid" and "too brave" for pitching hurt the past several seasons with the New York Mets.
"The last few years have been horrible," Martinez said. "I haven't felt the way I wanted to feel. I wasn't the same Pedro you were accustomed to seeing.
"Now that I'm totally healthy and I don't have my father [on his deathbed], I'll be able to be focused a little bit more and have more fun.
"I'm just here to prove it."
Martinez also was funny, in an egotistical-but-it's-OK-because-it's-Pedro sort of way.
"I bring with me a legacy," Martinez said. "I bring with me, my last name. I bring my face. I bring everything I have, my integrity, to this team."
Martinez also brings a thick jacket of questions about his usefulness, because of recent injuries, at a reported age of 37.
Immediately after signing him, Philly put him on the 15-day disabled list because of a shoulder strain — a procedural move, because Martinez won't be ready to pitch for two or three weeks.
Martinez, who previously pitched for the Dominican Republic in March during the World Baseball Classic, says to expect entertainment once he returns to the mound.
"I might surprise you," he said. "I might not. But it's going to be fun.
"I still have love for people in the Mets' organization, but I'm pretty sure I'm going to fall in love with the fans here."
Phillies general manager Ruben Amaro says he understands Martinez is a risk — though a sound one because of the possible reward.
