Skipped homecoming, too.
And the 17-year-old isn't spending a lot of time hanging out with pals at the mall, either.
Then again, none of the other kids back in Marietta, Ga., is preparing to play in the U.S. Open quarterfinals Wednesday night.
"She doesn't do any of that kind of stuff - and she's OK with it," Katherine Oudin said after sobbing in the stands when her twin sister pulled off a fourth consecutive upset victory at Flushing Meadows.
"I know she misses the normal life a little, but she does not regret it at all. Zero," Katherine said. "She's totally OK with it, because she knows this is what she's wanted her entire life."
That's a relative term, of course. When your "entire life" encompasses 17-plus years - and you began playing tennis at 7, hitting balls out of a bucket with Grandma Mimi - you haven't exactly been waiting forever for success. Indeed, Oudin is the youngest U.S. Open quarterfinalist since Serena Williams in 1999.
As the twins' mother, Leslie, put it: "All of this has come so quickly."
Sure has. A year ago, Oudin was ranked 221st and lost in the first round in New York. She never had won a Grand Slam match until Wimbledon in June. Nowadays, she high-fives security guards on her way into the locker room.
Everything is "awesome" and "cool," and she's "freaked out." Her stunning win over three-time Grand Slam champion Maria Sharapova? "I just had a blast."
