A spot in the next round is at stake on Wednesday, when Marco Trungelliti goes up against Rei Sakamoto in the Shanghai first round. Rei Sakamoto has won 5 of the last 10. Marco Trungelliti is 5-5 across recent matches.

Sakamoto's 73.7% behind the first serve (against 67.2% for Trungelliti) means break chances should be scarce in one direction. This one is close to a coin flip, and the lean toward Sakamoto is exactly that — a lean.
