Roddick and Verdasco in San Jose final

Top seed Andy Roddick fought back from a set down to win his SAP Open semi-final and set up a meeting with second seed Fernando Verdasco in San Jose.

Former world number one Roddick, chasing a fourth title at the tournament after wins in 2004, 2005 and 2008, claimed a 2-6 7-6 (7/5) 7-6 (7/4) win over fellow American Sam Querrey in one hour 59 minutes.

Verdasco earlier beat Uzbekistan’s Denis Istomin 6-3 2-6 6-4 to reach the final.

But it was Roddick who had the greater scare in the last four.

Seventh seed Querrey won the opening set at a canter, breaking the fearsome Roddick serve twice.

But Roddick bounced back, improving the accuracy of his first serve and taking the remaining two sets in tie-breaks.

Spain’s Verdasco awaits after seeing off the challenge of Istomin in one hour 43 minutes.

Verdasco was in charge after the opening set, but Istomin fought back with three breaks in the second set before the momentum again turned in the Spaniard’s favour.
