A spot in the next round is at stake on Wednesday, when Martin Landaluce goes up against Michael Zheng in the Los Cabos round of 32. Martin Landaluce is searching for form, having lost 4 in a row (5 of the last 10). Michael Zheng has won 5 of the last 10.
The two have never played — a first meeting always adds a layer of uncertainty the numbers can't fully capture.
On paper it's close: comparable ratings, comparable serve numbers, small margins everywhere. A tiebreak or two would surprise nobody, with Landaluce fractionally more likely to land the big points.
