In his latest mailbag, MetsBlog's Matthew Cerrone answers questions about Jacob deGrom, Edwin Diaz, Steven Matz, and what the Mets' bullpen could look like on Opening Day...
Why are the Mets and Jacob deGrom working to add a new pitch to his repertoire? It seems he's been doing pretty good without it. ~ Anthony M through Facebook.
I though the same thing, Anthony.
To be clear, though, deGrom is not adding a brand new pitch. He's simply working to perfect a backdoor slider (deGrom threw his slider over 31 percent of the time in 2019).
