Wikipedia - Federico Delbonis

Federico Delbonis (Spanish pronunciation: [feðeˈɾiko ðelˈβonis]; born 5 October 1990) is an Argentine former professional tennis player. He achieved a career-high ATP singles ranking of No. 33 on 9 May 2016. He also reached a career-high doubles ranking of No. 110 on 22 July 2019.

Delbonis was known for his unorthodox serve, an exaggerated trophy serve in which he would raise his racquet, toss the ball unusually high and follow through.
