Raphael Collignon vs Lorenzo Sonego — R16 — Swiss Open Gstaad

Break-point economy was the whole separation. Raphael Collignon cashed 1 of 2 chances to Lorenzo Sonego's 1 of 5, all the breaking done early — Collignon in game 3 for 2-1, Sonego back in game 4 for 2-2 — before the No. 7 seed's 87 percent of first-serve points won, to 71 across the net, steered both sets into breakers. The ATP No. 83 won the second-serve exchanges, 69 percent to 54, yet finished eight points light, 81-73. He saved three match points besides; Collignon converted the fourth, 2 hours, 8 minutes in, to reach the Swiss Open Gstaad quarterfinals having won all three tiebreaks he has played this week, his opener against Timofey Skatov included.
