Upton's absence from Monday's lineup is not due to injury, as he's considered to be healthy, Dennis Lin of the San Diego Union-Tribune reports.

EDGE Analysis

Since the All-Star break, Upton has been the subject of many trade rumors, so it's likely that the Padres are simply trying to protect the 31-year-old outfielder from any possible injuries before the trade deadline. Upton has yet to find his groove at the plate since the All-Star break, as he's gone just 3-for-20 with seven strikeouts in that time.
