The San Francisco Giants lost their third consecutive game when Mark Trumbo hit a grand slam to lead the Arizona Diamondbacks to a 6-2 victory Monday night. Trumbo had five RBIs, and Wade Miley (8-11) bounced back from his shortest outing of the season by pitching seven innings of one-run ball. San Francisco's NL West chances took a hit with consecutive losses to the Dodgers over the weekend, but the Giants are still in control of the wild-card race, beginning the day with a three-game lead over Pittsburgh for the top spot. What the Giants couldn't afford was a letdown in a three-game series at Chase Field, where they had won 16 of 22 games and six straight series since 2012.
