The Padres have bolstered their rotation as Spring Training gets underway, agreeing to a four-year, $55 million contract with free-agent right-hander Nick Pivetta, a source told MLB.com's Mark Feinsand on Wednesday night.

Nick Pivetta became the last of the high-profile free agent pitchers to reach an agreement this offseason, a backloaded $55 million, four-year contract with the San Diego Padres, a person familiar with the negotiations told The Associated Press.
