3 matches are on Friday's card at Seoul, and we have a pick for every one of them. The headline act: Seong Chan Hong against Terence Atmane in the quarterfinal. Our calls: Atmane over Hong, Wong over Shimabukuro, Sakamoto over Harris.

Coleman Wong vs Sho Shimabukuro

✓ Pick rightThis one lands on the correct side of the ledger: 64% on Coleman Wong, who won 7-6 6-1.

Pick: Wong

Coleman Wong and Sho Shimabukuro meet in the quarterfinal at Seoul on Friday. Coleman Wong has won 7 of the last 10. Sho Shimabukuro comes in at 4 wins from the last ten.

Hold strength tells the story — 74.8% versus 70.9% on first-serve points in Wong's favor. Wong comes in off a compressed schedule; Shimabukuro comes in off a compressed schedule. Expect resistance, but the match-level math tilts clearly toward Wong.

Billy Harris vs Rei Sakamoto

Not gradedThis match ended in a retirement, advancing Billy Harris. It is excluded from our graded record — no pick is counted as right or wrong.

Pick: Sakamoto

Win probability: 65% Sakamoto · Market: -310 · We call it in 3 sets (46%) · single likeliest score 2-0 (36%)

A spot in the next round is at stake on Friday, when Billy Harris goes up against Rei Sakamoto in the Seoul quarterfinal. Rei Sakamoto comes in at 5 wins from the last ten. Billy Harris comes in at 4 wins from the last ten.

Neither the serve numbers nor the ratings separate these two by much, which is why our number stays close to even. Sakamoto should have enough here, though Harris has the tools to make the scoreboard uncomfortable.
