Astros outfielders Carlos Gomez and Jake Marisnick combined for a full 25% of all Major League throws from the outfield of 100 miles per hour or better last season.

2015 was the year that StatCast data went live with the public, and the results, which we are now able to track relatively easily, are impressive. Throughout the season and during this offseason, the data has led to myriads of articles from many sources shining a light into the dark crevices of SABR sense and tying things that we already intuitively knew (like that Jake Marisnick and Carlos Gomez are superb defenders) to cold, hard data.
