The Padres needed to clear up two spots on the 40-man roster in order to accommodate recently signed relievers Craig Stammen and Kazuhisa Makita. One opened up when infielder Yangervis Solarte was traded to Toronto, and the other comes at the expense of Jose Rondon. The nearly 24-year-old shortstop spent all of last season in the minors, between AA San Antonio and AAA El Paso; his sole major league experience is eight games with the Padres in the summer of 2016.
Since coming to the Padres organization from the Angels in the Huston Street trade of 2014, Rondon has become something of a mainstay in San Antonio; he has spent the majority of the past three summers with the Missions. That trade looked fresh at the time, but the Padres received next to no production from their return. Taylor Lindsey and Elliott Morris never reached the majors, and RJ Alvarez made just 10 appearances with San Diego before being sent to Oakland as part of the trade for Derek Norris.
