The Pirates (7-14, 3-6) will now await a decision from the BIG EAST Tennis Selection Committee on Monday to see if they have received a bid to the 12-team conference tournament.
Seton Hall last appeared in the BIG EAST Tournament in 2006-07.
Sophomore Chloe Sher (Tin Shui Wai, Hong Kong) continues to establish herself as one of the upper-echelon players in the conference, scoring the only win for the Hall on the day.
Sher outclassed Syracuse's nationally-ranked top singles player Emily Harman, cruising to a 6-1, 6-2 victory.
Harman entered the match ranked #108 in the country and a winner in four of her last five matches.
Sher ends the season with a five-match singles win streak and an impressive 8-1 mark against BIG EAST competition.
The sophomore also improved 4-1 against opponents ranked either nationally or regionally this season and reaches the 20-win plateau for the second consecutive year.
With Syracuse penciling in only five players, Seton Hall received its other point by default in the number six singles slot after dropping two doubles matches.
Sher and her partner Rocio Portela (Demetrio Vega Baja, Puerto Rico) were tripped up by Harman and Amanda Rodgers, losing 5-8.
The loss snaps a 13-match unbeaten streak for the duo.
Despite Sunday's defeat, Portela and Sher have cemented their status one of the most prolific tandems in SHU history, setting Seton Hall records for single-season doubles wins (15) and career doubles wins (26) this year.
The SHU record book dates back to 2001.
In other action, Verow came up short in both singles action and doubles play where she partnered with freshman Madison Shoemaker (Halfmoon Bay, British Columbia), but caps a career that saw her consistently fill one of the top-three spots in the Pirates' lineup.
Verow also qualified for the ITA Regional Tournament four times in doubles and twice in singles.
Kilarski did not play in the match but leaves behind a résumé that includes two ITA appearances in doubles and the first title by a SHU doubles team at the Quinnipiac Invitational where she teamed with junior Karina Cordero (Maracay Estado Aragua, Venezuela) to take home the B flight crown earlier this season.
Should the Pirates get the call for the BIG EAST Tournament, play will begin on Thursday, April 19 from the USF Varsity Courts in Tampa, Fla.
