Padres Lineup vs Mariners: Ty France Starting Over Nick Castellanos, Miguel Andujar

The San Diego Padres kick off a three-game series with the Seattle Mariners on Tuesday night.

Entering Tuesday's matchup, the Padres are second in the National League West with a 10-6 record, only trailing the 12-4 Los Angeles Dodgers.

There is some cause for concern for the Padres as Nick Pivetta, who was poised to anchor the starting rotation, left his Sunday start against the Colorado Rockies with an elbow injury.

"I think we're optimistic that we caught it at the right time," manager Craig Stammen said about Pivetta.

However, a report The Athletic indicates Pivetta's injury could be more serious as the Padres are interested in signing free agent pitcher Lucas Giolito.

The Padres will have more information on Pivetta's status ahead of Tuesday's game. For now, they're focused on taking the series opener.
