The Grandstand’s Ricky Dimon and Jared Pine of The Second Serb preview and pick the best men’s singles matchups on Day 3 of the Australian Open. This is the third of 13 installments of expert picks during the season’s first Grand Slam.

Sam Querrey vs. (23) Ernests Gulbis

Ricky: Juan Monaco is a shadow of his former self right now, but any Grand Slam win for Gulbis is a good one. The Latvian did especially well mentally, coming back from a set down and taking the third in a tiebreaker before cruising in four. Santiago Giraldo is actually underrated on hard courts, but Querrey still should have finished him off long before a fourth-set tiebreaker. This ball-bashing affair between two erratic players will likely be back and forth, but of late Gulbis’ serve and backhand have seemed more reliable than Querrey’s serve and forehand. Gulbis 7-5, 2-6, 6-2, 7-6(3)
