Kyle Edmund ensured defending champions Great Britain made a flying start to their Davis Cup quarter-final against Serbia on Friday.
In the absence of Wimbledon champion Andy Murray - who was watching from the stands - Edmund was chosen to play singles in Belgrade and stepped up to the fore in a 6-3 6-4 6-0 beating of Janko Tipsarevic in a match heavily interrupted by rain.
Tipsarevic made 43 unforced errors in a disjointed performance, but world number 67 Edmund deserves credit for an aggressive display that saw him dictate the majority of the points.
The adverse weather conditions meant that Friday's other rubber between Dusan Lajovic and James Ward was pushed back to Saturday.
The United States took a 2-0 advantage against Croatia thanks to Jack Sock and John Isner.
Sock rallied past Marin Cilic 4-6 3-6 6-3 6-4 6-4 before Isner crushed Borna Coric 6-4 6-4 6-3.
Argentina hold a 1-0 lead over Italy after Federico Delbonis defeated Andreas Seppi 7-6 (7-4) 3-6 6-3 7-6 (7-3), but the rain in Pesaro meant the rubber between Fabio Fognini and Juan Monaco was postponed until Saturday.
Rounding off the action, the tie between the Czech Republic and France remains nicely poised at 1-1.
Lukas Rosol defeated Jo-Wilfried Tsonga in a five-set thriller, but Lucas Pouille overcame Jiri Vesely in straight sets to level the tie in Trinec.
