Here's a perspective on Alex Eala based on the lefty legacy in recent WTA history.
First, we have to acknowledge commonalities nearly all lefties have:
Spinny, versatile but not very fast serves
Amazing creativity and versatility on the FH
A BH that is oftentimes not a weapon
There's some variation obviously, and if we look at the gold standard for lefties in the last 15 years, Petra Kvitova, her big serve was definitely an exception.
But other than Kvitova, there really seems to be a performance ceiling for lefties and it seems to be around a ranking of 20.
Yes, players have reached higher than that, Vondrousova (#
6#) Haddad Maia (10), Fernandez (13) but none have been really able to sustain it
It's now been 6 years since we've had a lefty as a mainstay inside the top 10.
That of course was Petra, who was a fixture in the top 10 for nearly the entire period from 2011 thru 2020(!)
Some may find it silly that I am comparing Eala to other lefties, but if you believe as I do she shares characteristics with other lefty players then it's valid to speculate about a ceiling.
If Eala can pull it off and have a top 10 career, then her nationality won't be the only unique thing about her, a lefty doing this will also be very notable
