Marquez is a 22 yr old sinkerballer who is pitching rather well in AA. yes, the WHIP is high, but his GB rate is also high. I like him more for the fact that he has a solid arsenal and that he is young. Hence, why I think he projects more as a middle rotation or solid relief prospect.
Wright is 24 and I agree, he is struggling right now. But at the same time, he is a lefty with a nice curve and a solid changeup who has essentially the exact same arsenal as Gabbard and the exact same problems. This is why i was saying that a deal involving a player who is essentially Gabbard-esque, plus a higher risk/reward prospect would be a better move than getting a 17 yr old hitting .208 in the GCL.
