For a player who once served a record 10 consecutive aces, it was quite some admission by Sam Querrey that he felt he had served the best he had ever done in his straight-sets win over Olivier Rochus today.
Querrey fired down 18 aces in his 7-5 6-3 win over Rochus and won 34 of the 36 points (94 per cent) on his first serve.
It is a big weapon, aided considerably by the fact Querrey stands 1.98m. He routinely sent down bullets in excess of 200km/h whereas the diminutive Rochus, who is 30cm shorter, struggled to get many of his first serves over 160km/h.
Querrey in this sort of form looms as one of the threats to David Ferrer's quest for a third-straight Heineken Open title but Ferrer has also built his career around returning big serves. He's come across countless Querreys in his successful career and dispatched most of them.
Regardless, Querrey sees himself as a contender this week in Auckland if he can keep his serve together. He nearly won in 2009 but was beaten in the final by Juan Martin del Potro.
