Interim Padres' Manager Dave Roberts has left Justin Upton out of todays' lineup against Lance Lynn and the Cardinals. This just seems like a rest day for the Padres' everyday outfielder.
Despite the fact that Justin Upton is hitting an impressive .275/.360/.478 against righties this year, he is still getting a breather today. His replacement is the 32-year-old Will Venable batting 7th. Venable is hitting .258 with a wOBA of .321 and a nERD of .32 through 68 games this year.
