WTA MATCHES TO WATCH
DARIA GAVRILOVA (AUSTRALIA) VS.  SIMONA HALEP (ROMANIA)
Daria Gavrilova and Simona Halep are squaring off for the third time this season and second time in a month. Gavrilova won a clay court meeting in Rome in three sets, and Halep earned a 6-2, 6-3 victory two weeks ago in Montreal. Halep, seeded third, was a finalist here last year and enters Thursday on an 11-match winning streak with titles in Montreal and Bucharest. Gavrilova has taken the long road to the third round, winning two qualifying matches and a pair of matches in the main draw.
 ANGELIQUE KERBER (GERMANY) VS. BARBORA STRYCOVA (CZECH REPUBLIC)
Second-seeded Angelique Kerber and Barbora Strycova are also facing off for a third time this season. Kerber won on the Miami hard courts, and Strycova picked up a win on clay in Madrid. Kerber leads the all-time series 4-1. Kerber has spent a lot of time of the courts lately, making the semifinals in Montreal and the Olympic finals last week. A tournament victory this week would give Kerber the world No. 1 ranking. Strycova was also an Olympian, making the second round for the Czech Republic.
ATP MATCHES TO WATCH
 STAN WAWRINKA (SWITZERLAND) VS. GRIGOR DIMITROV (BULGARIA)
After his first match took two days and three sets to complete, No. 2 seed Stan Wawrinka will face another tough test when he takes on Grigor Dimitrov on Thursday. Dimitrov owns a 3-2 record over the Swiss, defeating him in their past three meetings. A former world No. 8, Dimitrov has put together two strong showings here in Cincinnati, defeating Feliciano Lopez in a third set tie-break Wednesday and Gilles Simon in the first round.
 RAFAEL NADAL (SPAIN) VS. BORNA CORIC (CROATIA)
Rafael Nadal admitted he was feeling fatigued after defeating Pablo Cuevas in his opening match, thanks to a packed match schedule in Rio. No doubt he will dig into his energy reserves when he faces 19-year-old Borna Coric Thursday. The pair has split their only two meetings, with Nadal taking their most recent encounter at last year’s US Open.
