MIAMI (AP) _ Right-hander Jeff Allison signed his contract with the Florida Marlins on Tuesday, four days after the first-round draft pick agreed to the deal.

Allison, 18, went 8-0 and didn't allow an earned run in 63 1-3 innings this season as a high school senior in Peabody, Mass. He was the 16th player taken in the draft.

He had a 15-minute bullpen session, surrounded by media, coaches and Marlins owner Jeffrey Loria. Allison said he wouldn't set unreasonable goals for himself, backing off the prediction he made after being drafted that he would ``make the All-Star team in two or three years.''

``I was just happy the day I was drafted,'' said Allison, who went 24-3 in his high school career with 378 strikeouts in 199 1-3 innings. ``The adrenaline was running and I didn't mean what I said.''

Pitching coach Wayne Rosenthal said he was impressed, as was manager Jack McKeon.

``Somebody did a real good job selecting this guy. He's got an outstanding arm,'' McKeon said. ``This kid goes out and pitches a few years, he could be in the majors very quickly.''

Allison, who is to report to the Marlins' rookie league affiliate in Jupiter on Wednesday, hopes to follow the lead of Dontrelle Willis, Florida's 21-year-old rookie left-hander, who went from the minor leagues to the All-Star game in a span of two months.

``Dontrelle is pretty amazing,'' Allison said.
