Couldn't find a thread dedicated to Anton in the Juniors forum, so decided to start one here, & I had heard so little about him & was intrigued to see something of his background reported in yesterday's London Evening Standard:

Analyst uses City skills to power his teen son to stardom

A financial analyst hopes his business acumen - and huge sacrifices - will help steer his teenage son to becoming a  Wimbledon star.

Anton Matusevich's meteoric rise has seen him practising with British stars, including Kyle Edmund.  Such is his promise that the 17-year-old, playing in the boys' singles event at Wimbledon this year for the first time, was handed a wildcard [sic] into the men's qualifying draw.  Despite losing to 21-year-old Czech player, Zdenek Kolar, Anton's family believe he has what it takes to reach the top.

Anton Matusevich Snr, 44, who works for HSBC in the City, said he was using his business nous to help his son.  He told The Standard:  "I work in the City, so am used to analysing things and working out risk.  I am good at setting out structure and getting conclusions.  I was trying to engineer something that would make a positive impact on his life.  I have also helped him with my own sports experience.  The sacrifices we have had to make - like Judy Murray with Jamie and Andy.  There is a lot that goes into it."

Anton, who is studying for A-levels in maths, further maths and economics, was born in New York after his father and mother, Kate, 43, moved from Russia in the mid-nineties.  Last year, he was regarded as the best 16-year-old in the world, helped by an incredible fastest serve [sic] of 135mph.

The fact that Anton was a wild card into the boys' singles & earlier today reached the quarter-finals lends credence to his parents' belief in him.  More power to his elbow!
