Saber warmup for alekskovacevic (ATP no.76) at rolandgarros with coach damionjackson, who tells me Aleks always like to use the saber for the first 2/3 mins for a number of things, his focus, hand eye and promote good rhythm on the stroke (Accelerate on contact) 🏷️ #alekskovacevic #ftsaber #tennisplayer #tenniscoach
