[1] Shortridge distinguished himself as a goaltending prospect at Eagle River High School as well as a local AAA organization.
In 2016, Shortridge began attending Quinnipiac University and split the starting role with Air Force transfer Chris Truehl.
He led Quinnipiac to a first-place finish in ECAC Hockey and though the team lost in the conference quarterfinals, the Bobcats' record was strong enough to earn them a bid into the NCAA Tournament.
[2] After Quinnipiac was eliminated by eventual champion Minnesota Duluth, Shortridge signed a professional contract with the San Jose Sharks and was assigned to their AHL affiliate for the remainder of the year.
While his numbers improved with the Allen Americans, Shortridge moved over to the Calgary Flames organization the following season.
