I believe I'm zeroing in on this Spritze. Let's look at Justin Verlander as an example. The first image is his real life real stats. The second image is his real life neutralized stats. In his neutralized stats he has one line (the second one) that matches up exactly with his 2015 real life stats. All good so far.
The line above that looks like an attempt to neutralize, but it looks like IP outs somehow got read as IP, so he has three times as many IP as he should have on that line. He has 309.0 IP on that line, whereas I would contend that it should be 103.0 IP. That would put things in line with the 2014 numbers for this neutralization, and the numbers make more sense when you do that. Total innings comes out to 236.0 instead of 442.0. ERA comes out to 3.89 instead of 2.08. WHIP comes out to 1.22 instead of 0.65. HR/9 comes out to 0.8 instead of 0.4. BB/9 comes out to 2.4 instead of 1.3, and K/9 comes out to 7.4 instead of 3.9. That sounds much more Verlanderish. Not to mention in that first line, the one with the 309.0 IP there's an impossible BABIP of .108. Normal BABIPs are usually almost three times that much - hence back to the suggestion that there are three times as many innings as there should be.
