When Jason Williams hit the third pitch of the game into the seats, the U.S. baseball team suspected its power was back.
When Mark Kotsay homered two pitches later, the Americans knew it.
"Back-to-back bombs!" pitcher R.A. Dickey said. "We just had to get the first one and we knew we'd start rolling. That's what it takes."
The United States rolled to its easiest victory of the Games Wednesday, drubbing Italy 15-3. The Americans hit four homers _ two by Kotsay _ to remain unbeaten in three games.
The United States has not played Cuba, the only other team without a loss. The round-robin tournament narrows a field of eight teams to four for medal play.
"This was Team USA at its best," said Dickey, who went five innings to get the victory. "We've traditionally been an offensive powerhouse."
Not lately. The United States hit just two homers and totaled 11 runs in its first two games.
Kotsay went 3-for-4 with two homers, a double and four runs batted in.
Cuba also pulled a power play, beating South Korea 14-11.
Juan Manrique homered twice and Jose Estrada hit a three-run homer as Cuba moved to 4-0. Cuba had 20 hits off five pitchers as it built a big lead, then held on while South Korea scored five in the ninth.
Cuban rightfielder Rey Isaac left after injuring his left hamstring while running the bases in the third inning.
