EDMONTON, Alberta -- Michelle Snyder's five RBIs helped the USA Baseball Women's National Team to a 9-1 victory over Cuba on Wednesday. Team USA improved to 4-1 in pool play at the World Cup.

Five U.S. pitchers helped guide the team to victory. It was led by three shutout innings from Stacy Piagno (2-0), who allowed just one hit and struck out two. Jennifer Hunter followed with two shutout frames. Marti Sementelli allowed a run in a 1/3 of an inning. Donna Williams and Kayla Bufardeci picked up the final five outs to lock up the win.

The U.S. opened a scoreless game in the fourth inning as it pushed across three runs. Williams got things started with a leadoff single and moved to second on a base hit by Tamara Holmes. Malaika Underwood gave the U.S. a 1-0 lead with a single to right. Caitlin Everett and Snyder each hit sacrifice flies for a 3-0 U.S. lead.

In the sixth, Team USA picked up a pair of insurance runs to take a five-run lead. Back-to-back doubles from Holmes and Underwood and a walk to Caitlin Everett loaded the bases. Snyder's second sacrifice fly of the game made it 4-0. Mackenzie Vandergeest lined a single up the middle to drive in Underwood for a 5-0 advantage.

Cuba finally cracked the scoreboard in the sixth as it pushed across a run on four hits. With one out and two on, Dainaris Morales singled to drive in the run. Two straight singles followed for Cuba, as it loaded the bases, prompting the U.S. to go to the bullpen. Williams got a big strikeout for out No. 2, then got a ground ball to end the inning with the 5-1 lead in tact.

Team USA broke the game open in the top of the seventh, scoring four times on three hits. Bessie Noll got things rolling with a one-out triple and scored on a Williams double. Two walks followed, loading the bases for Snyder, who cleared them with a double to left-center.

Bufardeci allowed a one-out infield single, but pitched around it with a pair of ground balls to lock up the win.

The U.S. returns to the diamond on Thursday afternoon when it takes on Chinese Taipei (3-2). Game time at John Fry Park is set for 4 p.m. (ET).
