Jackson was granted his release Saturday, and he intends to play in Japan next season, Corey Brock of MLB.com reports. Jackson made six appearances for the Padres last season, spending most of the year at Triple-A El Paso, where he posted a 2.54 ERA to go with a 1.147 WHIP in 48 appearances. The 28-year-old will sign with the Hiroshima Toyo Carp, leaving the Padres with 39 players on their current 40-man roster.
The Padres promoted four players Monday, including an experienced starter in Robbie Erlin, per MLB.com. Also brought up were infielder Cody Decker and pitchers Jay Jackson and Casey Kelly. Kelly and Erlin are slated to start at least one game before the regular season concludes. The latter has struggled in 20 major league starts and has yet to pitch for San Diego in 2015. Decker popped out in his first major league at-bat Monday.
The Padres optioned pitchers Robbie Erlin and Leonel Campos to Triple-A El Paso and re-assigned shortstop Diego Goris and pitchers Matt Wisler and Jay Jackson to minor-league camp Sunday. Erlin has started 20 games for the major-league team over the last two seasons. He finishes his spring with two earned runs allowed in six innings. Wisler, who is considered one of the team's top pitching prospects, allowed eight earned runs in five innings over three appearances.
The Brewers have acquired minor league right-hander Jay Jackson from the Pirates for cash considerations. Jackson is 5-4 with a 4.89 ERA at Triple-A Indianapolis. He will report to Triple-A Nashville.
The Pirates made several roster moves Tuesday, including optioning Jaff Decker and Jared Hughes to Triple-A Indianapolis. The Pirates also reassigned Robert Andino, Chris Dickerson, Jay Jackson, Michael Martinez , Omir Santos, Daniel Schlereth, Zack Thornton and Adam Wilk to minor-league camp.
