The Cincinnati Reds host the Colorado Rockies on Saturday in the second contest of a three-game series and hope their best hitter - Joey Votto - continues working out of one of the worst slumps of his career. Votto was 6-for-37 and hadn't driven a run in his last 10 games, and was 0-for-3 on Friday before clubbing a 3-0 pitch for a walk-off homer leading off the ninth inning as Cincinnati prevailed 4-3. "At the end of the year, you'll look up and I'll be about the same," Votto told reporters after hitting his fourth career game-ending homer. "The frustrating part is my struggles have coincided with a number of close losses."Colorado, the highest-scoring team in the majors at 5.7 runs per game, has recorded only three in its last two contests - both road losses. The Rockies' Nolan Arenado went 0-for-4 to end his club-record 28-game hitting streak while Troy Tulowitzki homered and went 1-for-4 to see his major league-leading batting average fall to .402.
