Here's a good breakdown of the Feliz trade from Call to the Pen:
Carpenter, 25, is a converted catcher who throws 91-94 with his heater. Like many converted players, his offspeed stuff is pretty raw. He still has managed to whiff 8.25 batters per nine this year in High-A. He has good command and keeps the ball down. Sometimes these converted guys wind up exploding onto the scene at some point. I wouldn’t go crazy projecting that for Carpenter, but he’s got some skills that could work out in the higher levels, and he’s still new to pitching, so he could make some real improvements.
On what it means for the Cardinals:
That the Astros got anything for Feliz is a miracle. As for the Cardinals…I see the whole “Tony La Russa can revive veterans” argument, and maybe he can. But when you have Ruben Gotay in AAA, there’s no excuse to acquire an inferior player in Feliz (with the additional cost of having to send a C-grade prospect away for him) to man the hot corner in St. Louis. No excuse, and it speaks to a lack of creativity in the organization that they’d rather go with the worst of retreads than one of the best players in Triple-A. The Cardinals are a great organization, and the Astros are not, but Ed Wade fleeced John Mozeliak on this one.
