No. We met Beth right before graduation, but she was shy and introverted. She was artistic, not an athlete. Although it's also a little unrealistic she wouldn't have known the fundamentals of tennis. Phillip was more than once described as "near pro level" at tennis, and gave lessons at the club when he was a teen. I believe it's also mentioned that Alan and Phillip won father/son tournaments at the club when Phillip was young. You'd think he would've introduced Beth to the fundamentals at some point during their marriage.
There's probably some psychology to a rape/abuse survivor being sexually aggressive, if she becomes attracted to a man and considers him being taken for granted in another relationship (which is the kindest way I can put her reaction to Vanessa.)
But mostly I think Brown and Esenstein (who I think are the ones who brought her back), simply plugged Beth into plots and reinvented her personality. Subsequent writers continued down this path, and Beth was usually 180 degrees from how she was introduced.
