Too bad for Kei, he becomes the biggest mover this week as his ranking dropped from no. 56 to 90!
In the meanwhile, here are some updates about Rendy.
He was at the SAP Open last week.
Although he did not play due to a knee injury, he was invited by the tournament director to attend several functions including an autograph session and meet the fans, participated in Kids' Day and spent the evening with fans (dinner and tennis matches).

Good luck to the both of them!
