What they’re saying

“I kind of went back to muscle memory at that point. Also got a little lucky twice there.”

— Alex Michelsen (10sballs.com)

“Today I was really impressed with how he served. I practice with him a lot. I don't feel like he normally serves that well. Just especially on the big points today, he just served incredible on a lot of the big points. When he really needed it, he'd put a serve on the line, a lot of first serves.”
