Baseball Prospectus | Fantasy Beat: Scherzer Demotion A Positive:
"One more thing to remember: Scherzer's ERA is 7.29, but his SIERA is 4.92. Even with his struggles, he was nowhere near as awful as his ERA suggested, and if he is promoted again and has his arm slot in order, both the ERA and his SIERA are going to drop back to the levels we expected him to be at when the year began."
I'm not as convinced as the young man from BP. Even a 4.92 ERA would make Scherzer a harmful SP in all formats.
