MIAMI - Nelson Cruz's two-out RBI single broke a seventh-inning tie, and the Dominican Republic overcame an early four-run deficit to beat Italy 5-4 Tuesday in the World Baseball Classic.
The Dominicans (4-0) remained unbeaten and advanced to a winner's-bracket game Thursday night in the double-elimination second round.
Robinson Cano had three hits, including his second homer of the WBC with a drive off the upper-deck facade in right field. Jose Reyes also homered for the Dominican Republic.
Chris Colabello hit a three-run homer, his second, to give Italy a 4-0 lead in the first inning.
Cruz has six RBIs in four WBC games.
The crowd of 14,482 was festive for the opening game in Miami, with horn-honking and chanting by Dominican fans who created a steady din. The retractable roof, closed for all but eight Marlins games last year, was open on an 80-degree afternoon.
Five relievers limited Italy to one hit and no runs over the final 4 2-3 innings.
Early wildness plagued Dominican starter Edinson Volquez, who threw only one of his first 13 pitches for a strike as he walked the bases loaded. Alex Liddi's sacrifice fly made it 1-0, and Colabello followed with a homer.
Volquez allowed four runs in 4 1-3 innings.
Tiago Da Silva went 5 1-3 innings for Italy and allowed two runs, both on homers. The Italians play in a losers'-bracket game Wednesday.
