Major league outfielders are getting smaller and faster

12 Comments

At FanGraphs, Eno Sarris did some digging and found that in 2016, for the first time since 1925, Major League Baseball saw only league-average production from its outfielders. He derived that by using wRC+, or adjusted Weighted Runs Created, a statistic that individually weights a player’s various offensive contributions, then adjusts for league and park effects. The offensive decline, Sarris finds, has a lot to do specifically with a decline in power, which is coupled with outfielders getting smaller and faster.

While we do have the stereotypical outfielder build in Mike Trout (6’1″, 235 lbs.) and Bryce Harper (6’2″, 230), we’re seeing lots of young players who defy that mold: Mookie Betts (5’9″, 156), Adam Eaton (5’9″, 180), Jackie Bradley, Jr. (5’10”, 195), Ender Inciarte (5’11”, 165), and Billy Hamilton (6’1″, 160), for example.

Sarris also compares current fourth outfielder types to those 30 years ago and finds that, indeed, clubs have eschewed power in favor of speed and defense. He suggests that this could lead to a market inefficiency in which these speedy, defensive types are overvalued and the slower, power-hitting types (like Brandon Moss) are undervalued.

Red Sox to extend protective netting at Fenway Park in 2018

The Red Sox are the latest team to extend the protective netting at their ballpark this winter. According to a statement by club president Sam Kennedy, the exact dimensions of the netting have yet to be determined, but it will likely stretch “all the way to Field Box 79, down the left field line and then all the way down to almost Canvas Alley in the Field Box 9 area.”

Fenway Park received additional protective netting prior to the 2016 season, when the netting behind home plate was lengthened to the home and visitor dugouts. Per Kennedy’s statement, the current expansion should cover everything but the outfield corners, making it nearly impossible for a line drive foul to reach fans in the lower boxes.

After a toddler sustained serious injuries from a 105-MPH foul ball to the face at Yankee Stadium last September, over half of all MLB teams decided to take more extreme preventative measures in advance of the 2018 season. The Brewers, Cardinals, Braves, Astros, Royals, Pirates, Rangers, Padres, Nationals, Mariners, Phillies, Mets, Reds, Blue Jays, Giants, Yankees, Twins and Indians are among the organizations to address the issue over the last several years, while others have yet to take significant action.
