Yordano Ventura's career run prevention #s concur at 4. (SIERA, xFIP, FIP). His SO #s are great but he walks a lot of people. This year he has been awful in almost every metric, but before 2016, he had solid No. 3 numbers.
He is young and his ceiling could be interesting in his prime, but seems like his head is somewhere else. If he is coached well (mentally and physically) he could end up posting what his career ERA says or maybe better moving forward. --3.8.
Am I interested?
Well, If he is supposed to be a depth arm --plus his upside and youth-- , I'll take him anyday of the week at a reasonable price, but if he is supposed to be the answer to our pitching problems, I pass.
