On December 16, 1993, he defeated Sean Fitzgerald with a KO in the first round to win the New England middleweight title. He defeated Frank Savannah by TKO to win the World Boxing Council Continental Americas middleweight title. In 1995, he defeated Chad Parker with a KO in the first round to win the WBC Continental Americas Middleweight Title.
His only professional loss came when 5-time former champion Vinny Pazienza knocked him out in the 4th round during a 1996 fight. In the opinions of some, it was a foul punch because the ref stepped between them to break, facing and blocking Rosenblatt, whereupon Pazienza reached around with a punch which knocked out the unprepared Rosenblatt. There was extreme animosity shown by Pazienza in the lead-up to the fight.
Rosenblatt broke his hand in his victory over Glenwood Brown in January 1997 and needed over a year to recover.
On September 25, 1998, he defeated former 3-time WBC super welterweight champion "Terrible" Terry Norris in a unanimous 12-round decision, to capture the International Boxing Association World Middleweight Title.
He defeated Will "Kid Fire" McIntyre, 36–4–1, in October 2000. Several injuries, including a torn right shoulder rotator cuff, a separated left shoulder and torn labrum, and a hand fracture, led to a 20-month hiatus. His next fight was also his last: in a technical against Juan Carlos Viloria on June 28, 2002, Rosenblatt was again injured. He announced his retirement in August 2003 with a record of 37–1–1 (23).
