Second up is Sam Querrey of the USA against James Ward.

GAME FOR WARD! Ward's 18th unforced error of the match so far (18!) give sup break point at 30-40 - but he saves it with a good point, Querrey finding the net as he's forced to run wide for a backhand. Ward then aces to go to advantage - and lashes down a second excellent serve that Querry can only chip over, setting up an easy winner. Ward off the mark!

ACES FLYING: Querrey smashes several aces down as he holds with complete ease once again. Ward has no answer to the home star right now - despite a very quiet, un-Davis Cup-like atmosphere so far.

WARD LOSES SERVE AGAIN: All going horribly wrong for the Brit as a double-fault sends Querrey to advantage, and he then nets a simple backhand to lose his fourth game in a row. Carbon copy of Murray's match so far: tough opening hold, then next three games rattle off in a row.

The stats gurus tell us that USA have lost 50 of the 81 Davis Cup matches they've played when losing the opening singles rubber. When they've won that opener, they've finished off their opponents over 90% of the time (in more than 200 matches).

QUERREY HOLDS WITH EASY: The big-serving American gets four good ones off, and Ward gets nowhere near any of them - it's a hold of serve to love, and the look Ward gives his opponent suggests he's expecting a tough afternoon in Southern California.

BREAK FOR QUERREY! The American's returns are too good for Ward in the Brit's opening service game, with the world number 175 looking slightly out of his depth in that one.

GAME QUERREY: Ward trails 40-15 in the first game but fights back to push it to deuce as Querrey makes a few mistakes. But the American holds firm in the end to hold. Tough opening game for both men.

Querrey serves first - these two have only played once, and Ward won that match - at Queen's in 2011.
