Djokovic, who is chasing a men's record 23rd Grand Slam to leapfrog Spaniard Rafa Nadal in the injured champion's absence, blazed past Peruvian marathon man Juan Pablo Varillas 6-3 6-2 6-2 in a lopsided last-eight clash.
World number one and top seed Alcaraz, another tenacious Spaniard who is backed to take the mantle of 14-times champion Nadal, bulldozed his way to a 6-3 6-2 6-2 win over Italian Lorenzo Musetti.
Pavlyuchenkova, who has slipped to world number 333 after being forced to stop playing for five months last year, is the lowest-ranked French Open quarter-finalist in the Open Era.
She (Kato) didn't do it on purpose, she (the ball girl) didn't get injured," Juge said.
She's crying," Sorribes Tormo said, pointing to the ball girl.
