Jeson Patrombon’s year-long international campaign and hard work are slowly paying off after his International Tennis Federation (ITF) world rankings improved by 91 notches.

Patrombon, 16, jumped from No. 242 two weeks ago to No. 151 this week – his highest world ranking in his young and promising career.

The Iligan City native earned valuable points at the Osaka Mayor’s Cup-World Super Junior Tennis Championships in Japan, a Grade A tournament which offers similar ranking points to Grand Slam events. His quarterfinal finish earned him 80 points.

Top Filipino junior netter Francis Casey Alcantara, on the other hand, saw his ranking fall from No. 34 to No. 55 this week.

Alcantara, who won the Australian Open doubles title alongside Taiwanese partner Hsieh Cheng-peng this year, lost in the Round of 32 of the World Super Juniors.
