MLB’s most popular jerseys: Cubs, Clayton Kershaw, more Cubs

If you measure popularity by jersey sales, four of the five most popular players in the major leagues play for the Chicago Cubs.

The other one is Clayton Kershaw.

To sell jerseys, apparently, it helps to play for the team that just won its first World Series in 108 years, or to be baseball’s best pitcher.

Cubs third baseman Kris Bryant ranked first, followed by Cubs first baseman Anthony Rizzo, Kershaw, Cubs second baseman Javier Baez and Cubs left fielder Kyle Schwarber.

Kershaw is not the only Dodgers player on the list. Shortstop Corey Seager, the reigning National League rookie of the year, ranked seventh. Angels center fielder Mike Trout, the reigning American League MVP, ranked 10th.

No other Dodgers or Angels player ranked among the top 20.

The average age of the players on the list is 26.5, according to Major League Baseball. The lowest previous average age had been 28, a heartening sign for a sport trying to promote a new generation of stars.

The list, announced Friday by Major League Baseball and the players’ union, is based on jerseys sold at the league’s online store since the end of the World Series.

1. Kris Bryant, Chicago Cubs
