Here's a look at some stars who have stood out among the crowd.
Cubs third baseman Kris Bryant had the best-selling jersey in all of Major League Baseball during the regular season, according to sales on the league's official website.
Cardinals manager Mike Matheny mostly took the high road Saturday morning when asked for a response to Cubs manager Joe Maddon's verbal attack on his organization the night before.
Joe Maddon unleashed a tirade directed at the Cardinals after they hit Anthony Rizzo with a pitch Friday. "We're not going to put up with that from them or anyone else," the Cubs manager said.
San Francisco Giants pitcher Madison Bumgarner, the World Series MVP, has had the best-selling MLB jersey in the first half of the season, according to the league's official website.
Cubs rookie Kris Bryant has been drawn into the same opening bracket as top-seeded Angels slugger Albert Pujols in the newly formatted Home Run Derby.
