The insights into pitching continues with reliever Shawn Kelley talking about a two-seam fastball today.

We’ve now had Chance Ruffin (slider), Steve Delabar (split-fingered fastball), Dan Hultzen (curve) and Kelley, and we’re working on a couple more pitches before we’ve run the table. No knuckleball spedialists in camp this spring.

If you’ve never fully understood the difference between a two-seam fastball and four-seam fastball, listen to Kelley on the video above – his explanation is simple. Enjoy

    Two-seam, four-seam never mattered to me. More important was the imprint of the seams on the hitter’s arm the next day, which meant I’d delivered an important message.

    Great stuff again Larry. When you get to Tom Wilhelmsen, can you have him show us how to make the perfect whiskey sour?
