Wikipedia - Oscar Otte
Oscar Otte (German pronunciation: [ˈɔskaʁ ˈʔɔtə]; born 16 July 1993) is a German professional tennis player. He has been ranked as high as world No. 36 in singles by the Association of Tennis Professionals (ATP), which he achieved on 27 June 2022, and has a career-high doubles ranking of world No. 161, attained in May 2017.
Since turning professional in 2011, Otte has won 23 singles and doubles titles on the ITF World Tennis Tour and seven on the ATP Challenger Tour. After several years of failing to qualify for most Grand Slam tournaments, he produced consistency in 2021 by entering into three consecutive main draws and showed his best performance at a major at the 2021 US Open, where he upset 20th seed Lorenzo Sonego in the first round and ultimately reached the fourth round. In January 2022, he made his top 100 debut in the singles rankings and emerged into the top 50 five months later, following his first career ATP 500 semifinal at the 2022 Halle Open.
