St. Louis Cardinals vs. San Diego Padres preview
The Cardinals and Padres clash Saturday night at Busch Stadium with both teams looking to gain traction in their respective playoff races.
San Diego has dropped three straight games, including Thursday's 9-7 series opener, and now sits five games behind the Dodgers in the NL West despite Manny Machado's productive season (24 doubles, 19 homers, 63 RBI).
St. Louis, nine games adrift of Milwaukee in the Central, will send the inconsistent Matthew Liberatore (6-7, 4.13 ERA) to the mound after he was roughed up for six runs in just three innings in his last outing.
Randy Vasquez (3-4, 3.73 ERA) gets the ball for San Diego and brings momentum from three straight quality starts, though his road numbers (4.34 ERA away from Petco Park) present cause for concern.
The Cardinals will be without the power bat of Lars Nootbaar (12 HR, 37 RBI), a significant loss for a St. Louis lineup that's been more productive at the plate (8th in batting average) than on the mound (22nd in ERA).
With the Padres struggling to generate offense (25th in runs scored) and the Cardinals having won seven straight home games against San Diego following a home victory, something will have to give in this pivotal mid-summer matchup.
