Injured Yuki out of top-200
India's Prajnesh Gunneswaran rose to a career-high of 84 in the ATP rankings released on Monday following his breakthrough run at the Indian Wells tennis tournament.
Injured Yuki Bhambri dropped out of top-200 for the first time in almost two years.
Prajnesh collected 61 points after reaching the third round at the ATP Master series event, where he beat World No 18 Nikoloz Basilashvili to register the biggest win of his career.
The performance helped him leapfrog 13 places to his new career-best ranking.
He was followed by Ramkumar Ramanathan (139), who dropped three places.
Both of them will try to qualify for the singles main draw of the Miami Masters this week.
Yuki, who is nursing a knee injury, slid 36 places to 207. The last time the Delhi player was placed outside the top-200 bracket was in July 2017.
Yuki is probably the most unlucky Indian singles player, whose progress has been halted by consistent injuries. Whenever he has managed to break the top-100 bracket, injuries forced him out of action.
The next best in the singles chart were Saketh Myneni (251, -5) and Sasi Kumar Mukund (268, +2). Mukund did not figure in even top-400 five months back and has shown good progress.
In the doubles, left-handed Jeevan Nedunchezhiyan touched a new career-high of 64 and was third highest-ranked played of the country after Rohan Bopanna (36,+2) and Divij Sharan (41, -1).
Purav Raja (80, -1) and veteran Leander Paes (94, +2) complete the top-five.
In the WTA rankings, Ankita Raina continues to be India's top-ranked player at 168 (-2) and was followed by Karman Kaur Thandi, who jumped seven places to 203.
