RIO DE JANEIRO -- The unheralded Brazil men’s field hockey team trailed Spain just 1-0 at halftime, and the host team’s boisterous fans smelled an upset.

The Spaniards responded with a flurry rarely seen in Olympic competition. They scored four goals in the third period and six in the second half of a 7-0 win Saturday night.

The four third-period goals came in an 11 minute span that left the locals deflated. Roc Oliva scored at 33:34, Josep Romeu scored off a penalty corner at 34:27, Xavi Lleonart knocked one in at 41:05 and Vincenc Ruiz capped off the barrage just 26 seconds before the end of the period.

Unsatisfied, the Spaniards tacked on two more goals in the fourth period. For perspective on the onslaught, just twice at the 2012 Games did a men's team score more than six goals in a match.
