Defending champion Canada prepares for Chile in Davis Cup group stage final

After a strong start, Canada needs a strong finish Saturday in its Davis Cup group stage final.

The defending champions of what's been dubbed the World Cup of men's team tennis wrap up group play against Chile after opening with sweeps of Sweden and host Italy in Bologna.

Canada (2-0) topped Group A of the 16-country group finals ahead of Italy and Chile (1-1) and Sweden (0-2).

The top two countries in each of the four groups advance to November's round of eight in Malaga, Spain.

After winning six straight matches over the first two days in Bologna, Canada's men had Friday off while Italy beat Chile in two singles and a doubles match.

Italy lost the first set of every match Friday, but recovered to win.

Lorenzo Muzetti and Lorenzo Sonego held off Chile's Tomas Barrios Vera and Alejandro Tabilo 6-7 (3), 6-3, 7-6 (2) in a doubles match to secure the sweep.

Italy and Sweden square off Sunday to conclude Group A competition.
