SAN DIEGO — Baseball's winter meetings ended with an old-style spurt of swaps, with All-Stars switching teams at a rapid pace and executives scrambling to fill roster voids. Alfredo Simon, Dee Gordon, Yoenis Cespedes, Miguel Montero, Jeff Samardzija, Brandon Moss, Dan Haren and Howie Kendrick were among the All-Stars dealt by the time teams headed home Thursday, and Matt Kemp and Jimmy Rollins were on the verge of switching clubs. The Los Angeles and Chicago teams were the epicenter of change, along with the Miami Marlins.
