The change-up is key for Strasburg even though it’s not his most used pitch; that’s the curveball at 30.7 percent. The pitch is dangerous because it sets up off the two-seam fastball, which he throws nearly 20 percent of the time. ADAD“No idea,” Guerra said in answer to Strickland’s question as to how Strasburg threw his change-up. This also heightens the importance of Strasburg’s two-seam fastball beyond a strategical setup because it ties the two pitches together. Strasburg threw his two-seamer far less often when Wieters caught him, and he started the left-handed hitter off with that.
