With Scooter Gennett's campaign for National League Player of the Month in its final push, the second baseman is starting to pull away from the field. The 28-year-old is hitting .392 with eight home runs and 22 RBIs this month for the Cincinnati Reds, who visit the Colorado Rockies on Sunday for the rubber match of their three-game series.

Gennett bolstered his candidacy Saturday with five hits, including a solo homer, as the Reds held on for a 6-5 victory. Jared Hughes, filling in for injured closer Raisel Iglesias, worked out of a no-out, bases-loaded jam in the ninth inning for his third save this season and the seventh of his career. Colorado has lost five of its last seven games but received a spark on Saturday from rookie second baseman Ryan McMahon, who was recalled from Triple-A Albuquerque prior to the contest and went 2-for-4 from the seventh spot in the order. McMahon is expected to start again Sunday in place of DJ LeMahieu, who has missed the last 11 games due to a sprained left thumb but hit in the batting cage Saturday and hopes to return in the next 2-3 weeks.

PITCHING MATCHUP: Reds RH Matt Harvey (1-2, 5.49 ERA) vs. Rockies RH German Marquez (3-5, 4.62)

Harvey earned his first victory in three starts with his new team on Tuesday, allowing one run and three hits over six innings against Pittsburgh. "It was a good step for me," Harvey told reporters. "I think there were times this year when I didn't think I was going to get another win in the big leagues. It was good to get one on the board." Ian Desmond is 6-for-22 with a home run against Harvey, who is 2-1 with a 1.88 ERA in four career starts versus Colorado.

Marquez turned in his best outing of the season on Monday, holding the Los Angeles Dodgers to one run and two hits over seven frames in a 2-1 victory. "It was my tempo, my aggressiveness," Marquez told reporters. "I was able to stay in the moment, one pitch at a time." The 23-year-old Venezuelan owns a 2.06 ERA in six starts on the road this season but has struggled at Coors Field, going 0-3 with a 10.34 ERA in four turns.
