 Two more Major League players have thrown their hat into the ring for the home run derby before the All-Star game the night before. Royals shortstop Bobby Witt Jr. and Braves outfielder Marcelo Zuna have each announced, I should say, that they'll be competing in the home run derby in Arlington, Texas. Phillies third baseman Alec Boehm is also taking part in the derby, which happens next Monday.
