Keys hits the hardest ball of any semi-relevant WTA player as confirmed by stats. Her average groundies (both sides combined) have been measured at higher speeds (78 mph) than Ostapenko's average on her fastest froundstroke this tournament (forehand = 76 mph). So yes, Keys hits harder. But both of them spray like mad unless they zone anyways. Luckily for Ostapenko, she has been zoning a lot this week.
