"I've tried to gain weight, but it never works," he said. "It doesn't matter how much I eat or what I eat. Nothing happens."
On Friday, with his quickness and handling of Jaep, Nardini helped Neumann-Goretti oust District 11 champ Blue Mountain, 9-2, in the resumption of a PIAA Class AAA state quarterfinal at Muhlenberg High.
In the sixth, he drew a walk and advanced on a delayed steal. On a terrific hustle play, while the Blue Eagles were trying to turn a double play on Marty Venafro's right-side grounder, Nardini scored from second to give Neumann-Goretti a 9-2 advantage.
Early in the season, Nardini batted second or in the leadoff spot. He has since settled in as the No. 9 man.
"I started the year off strong," said the 18-year-old, whose freshman brother, Tommy, is a reserve catcher for the Saints. "In the middle of the year, I was slumping a little bit. Coach Zolk decided to flip the order, so we'd be more complete from top to bottom."
Of calling the shots behind the plate, Nardini, who played third base as a freshman, said, "I love having that freedom. That's what makes the position so interesting. You're always thinking."
Against unfamiliar state-playoff foes, Nardini works without much of a scouting report.
"I can get a feel for things from a player's stance, where his hands are on the bat, and from where he's hitting in the lineup," he said.
Nardini, who lives near Broad and Pollock Streets in South Philly, will play baseball at the University of the Sciences. He plans to study physical therapy.
On Monday, 3 p.m. at Spring-Ford High in Royersford, the Saints will face District 3 titlist Lampeter-Strasburg in a state semifinal. A win would punch a ticket to Penn State's Medlar Field at Lubrano Park on Friday.
"To win a state title, that would be unbelievable," Nardini said. "It would be the best senior gift ever."
Trivia time. In 1977, the first year of the state baseball playoffs, Hatboro-Horsham, which will face La Salle in a Class AAAA semifinal at noon Monday at Spring-Ford, took top honors with a 4-0 victory over District 7's Penn Hills.
