Throughout the season, Richmond catchers combined to earn a perfect fielding percentage having not committed an error in 334 chances. A four-year starting shortstop at the University of Rochester, Mulberg and the Yellowjackets reached their first Liberty League Championship game in 2014, during which Mulberg hit .359 with an on base percentage of .468.

He ranks in the top 10 in school history in sacrifice hits, assists, double plays turned and most times hit by a pitch. He also was a member of the 2009 USA Gold Medalist Baseball Team at the 2009 Maccabiah. In 2014, Mulberg graduated cum laude from the University of Rochester with a bachelor’s degree in English and minor in business, and was elected to Phi Beta Kappa.
