Ricardas Berankis upset seed number two Tommy Haas in the second round of Houston 2013, John Isner and Nicolas Almagro also progressed.
Top seed Spaniard Almagro eliminated World No. 103 Gael Monfils after a three-set battle. The Frenchman took the initiative in the opener as he seized four consecutive games, including two breaks, to move one nil up. Almagro was a different player in the set number two in which he won 75% of the rallies and was breaking Monfils’s serve at will. The latter clinched only 9 points in that part of the game and was issued a bagel in the end. The deciding set went with serve until 4-3 when the Spaniard earned himself a break which he consolidated with a hold to love, thus making his way into quarterfinals of US Men’s Clay Court Championship. The scoreline: 2-6, 6-0, 6-3.
In an all-American clash fifth-seeded Isner overcame 119th-ranked Jack Sock after claiming a third set tie-break. It was always going to be a tight match in which last year’s runner-up Isner saved all four break points, while converting only one of them himself. That happened in the opening set which lasted 12 games. All of the serves were held in the following two sets – Sock managed to level the terms by winning the first of the tie-breaks, yet he conceded a few mini-breaks too many in the deciding one. Isner ultimately took this one with a 7-5, 6-7 (3), 7-6 (3) end score to progress into the next round in Houston. He hit 15 aces, while Sock stopped at number 13.
77th-ranked Lithuanian Berankis surprisingly beat second seed Haas in straight sets. The German was in a good form in recent weeks as he played in Miami semis, knocking off World No. 1 Djokovic in the process. Haas conquered Houston back in 2004, yet he only made it as far as the second round this time. He suffered three losses of serve in the opener which his opponent served out with the first set ball. Berankis held all of the serves in the following set, while breaking the German in sixth game and serving the match out after one hour and sixteen minutes of tennis. Final result: 6-3, 6-3.
