AL East and wild-card contender Tampa Bay made two trades Thursday, acquiring first baseman Lucas Duda from the Mets for minor-league pitcher Drew Smith and left-hander Dan Jennings from the Chicago White Sox for minor-league first baseman Casey Gillaspie, the 20th overall pick in the 2014 amateur draft and brother of Giants third baseman Conor Gillaspie. Smith, a 23-year-old right-hander, was a third-round draft pick by Detroit two years ago and was dealt to Tampa Bay in April. The Rays designated outfielder Shane Peterson for assignment to clear space on the 25-man roster for Jennings and the 40-man roster for Duda. The Nationals describe the injury as a “right elbow nerve impingement.” Baker says Strasburg will continue to throw in the bullpen and will pitch in a simulated game before the Nationals decide whether to bring him back. The White Sox placed All-Star outfielder Avisail Garcia on the 10-day DL with a sprained right thumb. Minnesota traded Triple-A catcher John Ryan Murphy to Arizona for Double-A left-hander Gabriel Moya.
