HALLE, Germany — As Dominic Thiem has cemented his place this year as a rising star of men’s tennis, his quality has been matched with quantity.
Thiem, 22, attained his career-high ranking of No. 7 after reaching the French Open semifinals. He has scored several notable victories along the way, pulling off the impressive double of beating Rafael Nadal on clay in Buenos Aires in February and Roger Federer on grass last week in Stuttgart, Germany.
But between his flashiest results, Thiem has labored through an unrelenting churn of matches at smaller tournaments, far surpassing the workload of any other man in the top 50.
