Sunday Notes: Danny Coulombe Executes Sliders and Curves
Danny Coulombe features a lot of breaking balls, and he does so with scant fanfare. In 28 relief appearances and one outing as an opener, the 32-year-old Minnesota Twins southpaw threw 41.8% sliders and 24.8% curveballs last year. He was also quietly effective. Taking the mound for a team that performed well below expectations, Coulombe logged a 3.67 ERA and a 3.75 FIP while fanning 33 batters and issuing just seven free passes in 34-and-a-third innings.
Emblematic of the lefty’s lack of fanfare is that I talked to him last August, and while I did include a few of his quotes in a September column — these on an online project management class that had him regularly visiting FanGraphs — I am just now sharing the crux of our conversation. What we delved into was the evolution of his breaker-heavy repertoire.
“I was predominantly four-seam/curveball when I got drafted,” said Coulombe, whom the Los Angeles Dodgers took in the 25th round out of Texas Tech University in 2012. “Coming up through the system I was mostly a curveball guy, and in 2014, a pitching coach I had, Scott Radinsky, told me that I needed something that looks like a fastball and moves. He said, ‘Right now, if a hitter sees a pop he knows it’s a breaking ball, and if he sees it straight he knows it’s a fastball.’ So we worked on developing a slider that year. I’ve always been able to spin a baseball, and now I’m probably about 70% breaking balls, curveballs and sliders.”
For Coulombe, maintaining a consistent differential between the two is a matter of mindset and grip. The latter required an adjustment, which was necessitated by unwanted blending. Read the rest of this entry »
