A's trade All-Star catcher Derek Norris to Padres (AP) — The revamping Oakland Athletics made yet another trade of a star player this offseason, sending catcher Derek Norris and minor league right-hander Seth Streich to the San Diego Padres on Thursday night for righties Jesse Hahn and R.J. Alvarez along with an international signing bonus slot. Oakland had depth at catcher, with capable backstops John Jaso and Stephen Vogt still on the roster despite both dealing with injuries last season. [...] baseman Josh Donaldson was traded to Toronto last month, then first baseman/outfielder Brandon Moss to Cleveland earlier this month.
