Bryan De La Cruz hit a two-run homer off Adbert Alzolay in the ninth inning, and the Miami Marlins beat the Chicago Cubs 3-2 in the opener of a split doubleheader. Luis Arraez collected three more hits for Miami, which had dropped four of five. Jesús Sánchez and Nick Gordon each had two hits. Arraez is batting .347 in his last 12 games. He singled with one out in the ninth, and De La Cruz followed with a drive to left-center for his fifth homer. It was the fourth blown save in seven chances for Alzolay.
