Isner and Querrey reach semis
John Isner and Sam Querrey set up an all-American semi-final at the SAP Open in San Jose as the top four seeds all progressed.
Second seed Isner saw off eight-seeded Belgian Xavier Malisse 7-6 (10/8) 6-2, while number three Querrey was a 6-3 4-6 7-5 winner against Colombia's Alejandro Falla.
Isner's first serve was nigh-on inpregnable - he won 37 of 41 he got in play and did not face a single break point - and once he had adged out Malisse in the first-set tie-break, it was plain sailing from there.
Asked what his tactics were, he said: "Just go out and throw a fastball. I'm not going to try to kick a serve. I'm going to go for it and try to end the point off my serve. I did that in this match, and I've done it a lot in my career."
Querrey found life more difficult against Falla but eventually prevailed in three sets.
The other semi-final will be between top seed Milos Raonic and fourth-seeded German Tommy Haas.
Canadian Raonic whitewashed Denis IStomin in a first-set tie-break on his way to a 7-6 (7/0) 6-3 win, while Haas needed just an hour and five minutes to see off American wildcard Steve Johnson 6-4 6-2.
