The San Diego Padres are suddenly scoring runs and hope to continue touching home plate when they visit the Cincinnati Reds on Tuesday to begin a three-game series. San Diego scored 24 runs while beating the Miami Marlins on three consecutive days after being the worst team in the majors in that category entering the four-game series. Cincinnati won two of three from Colorado over the weekend to improve to 10-8 at home.Reds third baseman Todd Frazier is on a roll with a career-best 11-game hitting streak and he smacked his seventh homer of the season in Sunday's victory over the Rockies. Reliever Aroldis Chapman made his season debut and struck out the side for his first save since being hit in the head by a line drive during spring training. Even with the sudden offensive splurge, the Padres are averaging just 2.97 runs per game but they are on the verge of getting Carlos Quentin back from a knee injury that has sidelined him all season.TV: 7:10 p.m. ET, FSN San Diego, FSN OhioPITCHING MATCHUP: Padres RH Andrew Cashner (2-5, 2.86 ERA) vs. Reds RH Mike Leake (2-3, 3.40)Casher has lost four consecutive starts after opening the season with four strong performances.
