<p>The pitcher throwing that ball? Former Blue Jay, Brett Cecil. Seeing that clip you would think that Cecil had something sticky on the ball, perhaps doing something he maybe didn’t do in Toronto? Looking at the numbers that doesn’t appear to be the case, Cecil’s spin on his curveball actually decreased in that first season in St. Louis.</p>
<p>On paper, the Blue Jays don’t look like a team that uses foreign substances. They rank in the bottom third among teams in average fastball and slider spin rate, per <a href="https://baseballsavant.mlb.com/">Baseball Savant</a> and in the bottom half of curveball spin rate. The teams at the top of these lists, the Dodgers, Yankees, Astros, Rays, are teams that have been suspected of using foreign substances. Other teams that stood out here were the Brewers and Pirates. On the most recent episode of <a href="https://bluejaysnation.com/2021/06/07/bjn-radio-ep-19-were-done-with-the-astros/">Blue Jays Nation Radio</a>, Tyler mentioned a Tik Tok account that was posting videos of players rubbing their gloves and having sticky fingers. I found the account; <a href="https://www.tiktok.com/@hey_commy?lang=en">@Hey_Commy</a> and many of his videos have been centred on the Brewers three-headed monster of Brandon Woodruff, Corbin Burnes and Freddy Peralta. He also shows numerous Pirates pitchers as well, so seeing those teams ranking near the top of a spin rate list isn’t surprising.</p>
<p>With crackdowns on pitchers already here and more coming very soon, I decided to look at the Blue Jays pitchers to see who if any will be affected by this. I went through every pitcher who has pitched this season for the Blue Jays (with the exception of Ty Tice and Alek Manoah as this is their first big league season) and compared the spin rate of their 2021 fastball to their 2020 fastball. Where applicable I added in the pitcher&#8217;s 2019 spin rate for further context. Pitchers that came to the Blue Jays mid-season will have two spin rates, the first showing their fastball spin with their former team and second with the Blue Jays. All spin rate data courtesy of <a href="https://baseballsavant.mlb.com/">Baseball Savant.</a></p>
<p>Here are the results sorted by those pitchers with the largest spin rate increase.</p>

<p>*sinker spin rate was used instead of four-seamer</p>
<p>At this point in time seeing a large jump in spin rate is suspicious. That’s not to say any of these players is using a foreign substance.

If Major League Baseball is going to investigate anyone on the Blue Jays those first five pitchers seem to be the most likely.</p>
<p>Should that be the case this could have a big impact on the Blue Jays (though not as much as other teams). Romano has been the team&#8217;s most valuable reliever to date. Borucki was the team&#8217;s primary lefty when he was healthy, and Merryweather in just 4.1 innings this season has been the fifth most valuable Blue Jays pitcher this season. When all are healthy those are three key bullpen arms, so it would be an issue should any one of them see a large spin rate decrease.</p>
<p>The Blue Jays have had plenty of turnover on their pitching staff over the last three seasons bringing in a variety of arms from outside the organization. Those arms typically see their spin rates stay the same or even decrease. The pitchers that have been corrected and “fixed” by the Blue Jays and Pete Walker have typically come from mechanical adjustments and not some secret stuff. Every team will be affected should Major League Baseball put forth a serious crackdown on foreign substances.
