Saturday's Porto semifinal pits Henrique Rocha against Jerome Kym on hard. Jerome Kym has won 3 in a row and 7 of the last 10 overall. Henrique Rocha is rolling — 3 straight wins, 6 of 10 in recent play.

The serve is where this match separates: Kym has been winning 74.8% of first-serve points to Rocha's 67%, and on hard that gap compounds fast. Rocha comes in off a compressed schedule; Kym comes in off a compressed schedule. A tiebreak or two would surprise nobody, with Kym fractionally more likely to land the big points.
