Over the years, the iPad has become popular in all sorts of segments of the market. Now, a new report from Boston.com – shared by Apple’s Phil Schiller on Twitter – dives into how Boston Red Sox All-Star J.D. Martinez relies on his iPad day in and day out…

The story explains that Martinez attaches a pair of iPads to tripods and places one on either side of the batting cage during batting practice. From there, a third iPad – Martinez’s personal device – is used to record the batter’s box, something he has done since 2015.

After batting practice, Martinez goes to the team’s clubhouse to review the footage recorded by the three iPads, helping him train himself to become a better hitter. He explained that he looks for similarities between swings:

When the 30-year-old Martinez steps up, video coordinator Billy Broadbent will point a third iPad at the batter’s box — Martinez’s personal device, which he’s used to record his practice cuts since 2015.

After he was released by the Houston Astros in 2014, Martinez started using his iPad with his new team, the Detroit Tigers. The team, however, was full of veteran players and Martinez was made fun of for his reliance on the iPad. That changed the next year and has continued since Martinez joined the Red Sox.

“Similarities,” he said. “It’s like the game; ever play the game matchup and what’s different in this picture? You have two pictures side by side. That’s pretty much what I do.

The full piece is definitely worth a read and can be found here.

“In ’14 I was too scared to do it with Detroit because I was too young, and it was an older team,” he said. “In ’15 I had more confidence.”
