Give her a break, she's playing someone who's 6' 2" on a fast indoor court with a huge left first serve which her whole game is based around, it's not easy.
point taken. but she must be returning Pliskovas serve well to get the 15 break pts in the first place. She's just not returning it well at the key times. But, yeah, maybe Pliskova is hitting bombs on the bps.
