Johns Creek, Georgia ( - Sam Querrey posted a first-round victory Monday at the Atlanta Open tennis event.

Querrey will next face Israeli Dudi Sela, who routed Atlanta native Donald Young by a 6-3, 6-0 count in Monday's other opening-round bout.

This week's top seed is 6-foot-10 American, reigning champion and two-time runner-up John Isner, who beat 6-foot-8 South African Kevin Anderson in last year's all-tall finale in Atlanta.

The 2014 Atlanta champ will claim $103,000.
