Do teams know something about these guys that we don't know?
It happened like this, more or less. Jimenez's second half was Koufaxian, with 100 strikeouts to 27 walks in 84 innings. He allowed 13 homers before the break and three after. His overall season line looked superlative, which is gobsmacking when you see the route Jimenez took to get there.
Santana's line isn't as impressive on the surface, at least when it comes to strikeouts. But considering the difference between ballparks, Santana was probably better at preventing runs when adjusting for context (127 ERA+ to Jimenez's 114). There's certainly a neater distribution of good starts and bad starts, partially explained by the preponderance of hackers and wavers Jimenez got to face in the second half.
