Clark ripped a 1-0 pitch down the line and coasted into second standing. Blake Smith (California; Modesto, Calif.) followed with a sharp grounder up the middle on which Canada shortstop Sammie Starr made a diving stop and got Smith at first. That pushed to Clark to third, though. Canada pitcher Brandon Kaye got ahead of Ryan Jackson (Miami, Fla.; Miami Springs, Fla.), but Kaye's 0-2 pitched skipped to the backstop, and Clark scored easily.
That made a winner of reliever Mike Leake (Arizona State; Fallbrook, Calif.), who allowed a hit and no walks with three strikeouts over two scoreless innings. Kaye took the loss, entering the game to start the 11th.
It was not an easy victory for Team USA by any stretch of the imagination. Canada built a 3-0 lead thanks to shaky U.S. defense, scoring an unearned run in the fifth and two more unearned runs in the seventh.
Team USA tied the game on a pair of hits and a Canada error in the bottom of the eighth. Hunter Morris (Auburn; Huntsville, Ala.) drew a pinch-hit walk to lead off the eighth, and Derek Dietrich (Georgia Tech; Parma, Ohio) followed with a single.
The U.S. squad then got the break it needed. Matt den Dekker (Florida; Fort Lauderdale, Fla.) grounded into what appeared to be a double play, but Starr mishandled the ball at shortstop. That allowed pinch-runner Scott Woodward (Coastal Carolina; Markle, Ind.) to score from second, and it gave Team USA runners at second and third with no outs. Christian Colon (Cal State Fullerton; Corona, Calif.) followed with a game-tying, two-run single back up the middle.
U.S. starter Andrew Oliver allowed an unearned run on one hit and five walks with five strikeouts over 5 1/3 innings. A.J. Griffin (San Diego; El Cajon, Calif.) was touched for two unearned runs on two hits and a walk over two innings.
Canada starter Mat Wilson allowed three runs, one of which was earned, on six hits and three walks with four strikeouts over eight innings. He did not factor in the decision.
Dietrich had the only two-hit game for Team USA.
Team USA continues pool play Wednesday, facing Japan. First pitch is scheduled for 3:30 a.m. EDT at City Baseball Stadium.
