Chicago Cubs vs Arizona Diamondbacks

PHOENIX -- — Pinch-hitter Ryan Waldschmidt hit a game-winning, two-run homer with two outs in the ninth inning and the Arizona Diamondbacks rallied to stun the Chicago Cubs 5-4 on Tuesday night. The D-backs pulled one game behind the San Diego Padres for the final NL wild-card spot. Trailing 4-3 in the ninth, Tim Tawa coaxed a one-out walk from Jacob Webb to start the decisive rally. Ildemaro Vargas flew out to right field for the second out before pinch-runner Jose Fernandez stole second base. Waldschmidt — a rookie — then launched a no-doubt homer over the left field fence to set off a raucous celebration. It was Waldschmidt's second walk-off homer of the season. Arizona trailed 4-0 in the eighth before mounting a two-out rally against reliever Daniel Palencia. Gabriel Moreno hit a check swing RBI double that hugged the first base line and stayed fair before Geraldo Perdomo's two-run single cut the deficit to 4-3. Webb relieved Palencia and coaxed a ground out from Max Kepler to end the threat. Ian Happ hit a three-run homer in the fourth to push the Cubs ahead 3-0. Michael Busch's RBI single in the sixth made it 4-0. Busch and Seiya Suzuki both had two hits. The D-backs' rally ruined a great outing for Clay Holmes, who breezed through the D-backs' lineup, giving up two singles and two walks while striking out five over seven scoreless innings. The right-hander has given up just one earned run over his past 19 innings, spanning three starts. Arizona's Brandon Pfaadt (7-2) gave up four runs on six hits and two walks, striking out three. He didn't allow a hit over the first three innings, but gave up a single and a double in the fourth before Happ's three-run homer.
