A spot in the next round is at stake on Wednesday, when Kasidit Samrej goes up against Yuta Shimizu in the Phan Thiet 3 (Vietnam) round of 16. Kasidit Samrej has won 5 of the last 10. Yuta Shimizu is searching for form, having lost 2 in a row (4 of the last 10).

The serve is where this match separates: Samrej has been winning 71% of first-serve points to Shimizu's 67.7%, and on hard that gap compounds fast. Samrej comes in off a compressed schedule; Shimizu comes in off a compressed schedule. A tiebreak or two would surprise nobody, with Samrej fractionally more likely to land the big points.
