Fresh off of back-to-back wins over Roger Federer and Tomas Berdych – the latter in three straight sets – Gulbis has become somewhat of a quiet force in the late stages of the Roland Garros tournament.

His 20/1 odds of winning the French Open pale in comparison to 10/11 mark, but do a fine job of emphasizing the Latvian’s unexpected run to the penultimate match. After trailing by a set against Federer in the fourth round, Gulbis rallied for and improbable victory against the living legend and he hasn’t looked back since.

While knocking off the No. 4-ranked Federer and then No.6-ranked Berdych is impressive, however, there’s a reason why Djokovic slides in at No. 2. Between Djokovic and No. 1 Rafael Nadal, there remains plenty that could go wrong in Gulbis’pursuit of yet another upset. Ranked No. 17, and listed as the 18th seed in the French Open bracket, Gulbis has come out of nowhere as an intriguing tennis betting option.

There’s no guaranteeing that his luck will continue in the final rounds at Roland Garros, but it’s something we’re excited to see.
