Friday's Hangzhou round of 16 pits Hugo Gaston against Jaime Faria on hard. Jaime Faria has won 6 of the last 10. Hugo Gaston limps in on a 2-match losing skid, just 6 wins in 10.

The serve is where this match separates: Faria has been winning 71.1% of first-serve points to Gaston's 65.7%, and on hard that gap compounds fast. This one is close to a coin flip, and the lean toward Faria is exactly that — a lean.
