The San Diego Padres have added outfielder Nick Castellanos and pitchers German Marquez and Griffin Canning to their roster. Marquez, a former Rockies starting pitcher, has reportedly signed a one-year deal. The exact nature of the transactions, whether through free agency or trade, is not specified in all reports, but it appears the newcomers will be part of the team's plans, with Marquez and Canning potentially competing for a spot in the rotation.
