Saw an old friend of mine on television yesterday.

Name's Vasek Pospisil, 29 years old, currently the No.187-ranked tennis player in the world.

Never met the man.

Do I know him?

Sure do, and a whole lot better now.

Yesterday at the U.S. Open in New York, Pospisil reminded me--again--what character is all about.

It's something I've learned over the years covering sports, but it sometimes slips my mind--until somebody plants a giant smack on the side of my head.

That's what happened yesterday.

One upon a time, Vasek Pospisil was a comer--getting as high at No. 25 in the world, winning a Wimbledon men's doubles title, competing as a finalist in a pretty big tournament in Washington D.C. against a guy he came up with, Milos Raonic.

But injuries have taken their toll and over the years, his star has faded.

Until yesterday.

Pospisil stepped on to the court having played just two top-tier matches since October, both of them losses to hotshot Canadian Felix Auger Aliassime.

His opponent: No. 9 seed Karen Khachanov of Russia, 23-years-old, and a pretty tough hombre.

You want tough? You want nerves of steel? You want a will of iron?

That was Pospisil yesterday, all of a sudden like the guy a lot of people were talking about over a half-decade ago.

Three hours and 51 minutes later, Pospisil had a 4-6, 7-5, 7-5, 4-6, 6-3 victory.

It was the first fifth-set victory for Pospisil since he had three on his way to a quarter-final result at Wimbledon in 2015.

It sure would have been lovely to have been there.

Stephanie Myles was.

Myles, the editor-in-chief for tennis.life, was covering the match for Canadian Press.

I spoke by phone with her this morning.
