The Mets' use of advanced analytics and data was one of the reasons the team stuck with Curtis Granderson when he was struggling badly earlier this season.
Granderson, who was hitting just .122 in early-May, was "tremendously unlucky" on batting average on balls he put in play (BABIP), assistant hitting coach Pat Roessler said recently, according to SportTechie.
"He was really pretty good," Roessler said last week at the SABR convention. "You try to use that to keep their confidence up and keep them in the right frame of mind."
"We know in here that it's more than just your average to determine if you're playing well or not," Granderson said recently.
For the season, Granderson is now hitting .236 with a .332 OBP and .480 SLG with 13 HR in 79 games.
His BABIP is .258, still well below his career BABIP average of .295. Granderson's hard hit percentage is 35.9 percent (it was 36.9 percent last season), but his soft hit percentage is 19.5 percent -- well above his career rate of 15.1 percent.
According to SportTechie, the Mets' use of advanced data also led them to revamp Jay Bruce's hitting approach and advise Seth Lugo and Paul Sewald to use certain pitches more often based on their spin rates.
Roessler and hitting coach Kevin Long told Bruce to focus on hitting the ball in the air to right field.
Bruce, who is hitting .256 with a .328 OBP and .516 SLG with 21 HR, has the highest fly ball rate of his career -- 48.9 percent (up from 41 percent last season). His home run per fly ball rate is actually down, though, from 19.4 percent to 18.3 percent.
"There are so many numbers and percentages and rates and ratios that you can chew on, but how do you melt that down to make it applicable?" Bruce said. "A lot of people, I think, tend to maybe run from information a little bit. Well, I like to have information. I'm not saying I'm going to use it all. I wanted to figure out how to apply that information I got in the most simple form. For me, it was get balls you can hit in the air and you can drive. And it's really helped."
