The Rams joined Cherry Hill West's legendary teams from the late 1980s and early 1990s as the only baseball programs in New Jersey to win four consecutive state titles.
Gloucester Catholic (29-5) also won its 17th state title, more than twice as many as any other program.
"I can't even put it into words," said Gloucester Catholic senior righthander Mike Shawaryn, who was the winning pitcher in his last game in a maroon-and-gold uniform. "I couldn't have done it with a better group of guys."
The win in a taut game in front of a large crowd that circled the sunken field held extra meaning for the Rams seniors as well as their first-year coach.
Rucci, who won three state titles for Gloucester Catholic as a player, admitted to feeling "100 percent" pressure in replacing legendary former coach Dennis Barth, who left the program after last season to become the head coach at Rutgers-Camden.
"He was there for me the entire year," Rucci said of Barth, who was on hand Sunday to watch his former team win another state title.
For the Rams seniors, the victory over Seton Hall Prep (30-3) stamped them as the program's only class to capture four state titles.
"It's unreal," said Gloucester Catholic catcher Jon Theckston, who suited up for all four state-title teams.
Gloucester Catholic took a 1-0 lead in the third as sophomore Fran Kinsey singled, stole second, and scored on a two-out, RBI single by sophomore Anthony Harrold.
The Rams made it 2-0 in the fifth as junior Phil Dickinson singled, advanced on an error, and scored on a fielder's choice by sophomore Sean Breen.
Shawaryn, a Maryland recruit who was drafted by the Kansas City Royals in the 32d round on Saturday, worked six innings. He allowed four hits with seven strikeouts.
Sophomore John Murphy worked a 1-2-3 seventh inning for the save.
"He had everything going," Theckston said of Shawaryn.
