    Should pitchers grunt?

    While perusing baseball-related academic journals in preparation for our podcast (sorry, it was just as painful for me writing that as it must have been for you reading that), I came across the following, which I thought this was interesting: Justin Tammany at Hardin-Simmons University and...

    Spin mirroring and Red Sox pitchers (another reason to love Tanner Houck)

    I’m a big Tanner Houck fan. In his limited time up with the Sox this year, his sinker displayed some crazy vertical movement and his slider’s horizontal movement was among the top 20 in all of MLB. He’s also a big seam-shifted wake guy. And he might just be our last, best hope of keeping the...

    Using similarity scores to determine Sam "Mayday" Malone's most similar pitchers

    This week marked 28 years since Cheers went off the air. We commemorated the occasion with a review of Sam Malone’s career pitching line on (oh God, is he going to plug his podcast within a main board post?) our (no, he wouldn’t dare) podcast (Can you believe this guy? He actually did it!). Did...

    I've spent a lot of time thinking about Phillips Valdez lately. For example, the amount of Seam-Shift Wake movement on his changeup is 6th-best in all of MLB (min. 100 pitches)! But, here's something odd I stumbled across -- his release point on his slider relative to the rest of his repertoire...

    Seam-Shifted Wake, Red Sox Pitchers, and You

    TL;DR Seam-shifted wake, or side force, is the difference between a pitch’s observed spin and its measured spin, as detected by MLB’s recently-installed HawkEye systems. Players whose pitches exhibit this type of movement have become hot commodities, driven by a number of the more...

    Huh, Wade Miley projects to be pretty valuable

    I just started paying attention here so maybe it's already been covered but I was surprised to see that Miley projects to be about as valuable as some of the second-tier FA starters that I suspect some of the "smart" FOs will be targeting once Greinke is off the board. Cueto and Lackey are a cut...

    Getting to Know Yoenis Cespedes

    He's now a Red Sox. What should we know?   Consider it a placeholder for now but, here's his FanGraphs page to start: http://www.fangraphs.com/statss.aspx?playerid=13110&position=OF
