The junior carded a 6-over par 78 to finish three shots behind the winning score. Four golfers tied at 75, three tied at 76, two tied at 77 and four, including Garcia, tied at 78.
Staples coach Bob Byiteck applauded Garcia, a transfer from Trinity Catholic, for her play this season. Garcia finished fourth among Connecticut golfers at New Englands.
"She took the level of play for the rest of the Staples girls to a higher level," he said. "Her commitment to the game was outstanding."
Garcia competed all season as Staples' No. 1, scoring in the 30's six times.
"This will be a real test," Byiteck said.
