A beloved tennis player from Las Vegas is dead after collapsing during a match.

His sister-in-law Catherine performed CPR but to no avail.

The lifelong tennis player apparently had high-blood pressure, which his family has a history of. However, doctors said that he had been on the wrong medication for it.

His death is a shock for the family.

"He took impeccable care of his health," his sister Tami King said. "He was so fit. He lifted weights. He looked like a bodybuilder to me. He was huge. We did not see this coming."
