Sunday's French Open first round pits Ajla Tomljanovic against Caty Mcnally on clay. Ajla Tomljanovic is searching for form, having lost 4 in a row (4 of the last 10). Caty Mcnally has won 6 of the last 10.

Caty Mcnally leads the head-to-head 3-0, and history has a way of mattering in matchups like this one. On clay specifically it reads 1-0 Mcnally — worth more than the overall number this week.

Tomljanovic's 63.3% behind the first serve (against 60.1% for Mcnally) means break chances should be scarce in one direction. This one is close to a coin flip, and the lean toward Tomljanovic is exactly that — a lean.
