[3] McGee had finished 2013 in good form and continued this into 2014, reaching the semi-finals of the BNP Paribas de Nouvelle-Calédonie in Nouméa, equalling his best performance at a challenger.

[5] McGee later recorded an impressive win over top 100 player Alex Bogomolov, Jr.[6] at the Challenger of Dallas and then narrowly missed out on making his first ATP World Tour main draw the following week, losing in the final round of qualifying at the U.S. National Indoor Tennis Championships to David Goffin.

[6] In March, McGee played in qualifying for the BNP Paribas Open, an ATP World Tour Masters 1000 event, but was again defeated by Goffin.

[8] He then went on to win his first ever Grand Slam qualifying match, defeating Norbert Gomboš at the French Open and then stunning Guido Pella in two sets in the following round.

McGee, however, was unable to become the first Irish tennis player since Sean Sorensen, in 1982, to reach the French Open main draw, as he lost in straight sets to Andrea Arnaboldi.

[9] In early June, McGee once again reached the final round of qualifying for an ATP World Tour event, this time at the Queen's Club Championships, but came up just short in a tight three sets match against Daniel Brands.
