Monday's French Open quarterfinal pits Anna Lena Friedsam against Mona Barthel on clay. Anna Lena Friedsam comes in at 3 wins from the last ten. Mona Barthel is searching for form, having lost 4 in a row (1 of the last 10).

The two have never played — a first meeting always adds a layer of uncertainty the numbers can't fully capture.

The underlying stats are tight across the board — this is a matchup decided by a handful of points. This one is close to a coin flip, and the lean toward Friedsam is exactly that — a lean.
