Sixth-seeded Carlos Berlocq of Argentina overcame an injury to his left calf and surged past James Blake of the United States 6-4, 2-6, 6-1 in a first-round match at the US Men’s Clay Court Championships on Monday night.
Berlocq took early charge with a 5-1 lead in the first set and then had to hold on to win the opening set. Blake easily won the second set with Berlocq getting his ailing calf wrapped before losing the final game of the second set.
Berlocq said he felt tightness in his left calf. He left the court briefly before the final set to get more treatment.
Instead of fading, Berlocq was energized from the start of the final set. Blake held serve in the first game, but then Berlocq won six straight games.
Berlocq broke Blake in the final game at love. He hit a backhand return of service winner at the first match point.
Berlocq said he first felt pain in his left calf 10 days ago and felt it tighten again early in Monday night’s match.
Sam Querrey of the United States, a 2010 finalist, beat Eric Prodon of France 6-1, 6-4 in another first-round match.
Former champion Tommy Haas withdrew with a right knee injury prior to a qualifying match.
