From fangraphs on Rooney when they listed him 37th on the Dodgers prospect list: It'll be interesting to see what the Dodgers player dev staff molds Rooney into, because there is indeed interesting raw material to work with. Rooney doesn't throw all that hard, but his fastball plays up a bit thanks to good angle and extension, he has impressive changeup feel (and an incredible pickoff move) for a cold-weather, small school prospect. His curveball is hard, has good shape, but lacks bite and raw spin. On stuff, he looks like a depth arm, but there are some late-bloomer traits here. Realistically, he could grow into a backend starter.
This trade was possible because John Rooney has spent the entire season in the minor leagues without having his contract selected by the Marlins. I'm pretty sure that he has never been on their 40-man roster either. Please refer to the article below:
Pressly's a weird one. From Apr 1 to the All-star-break, he had an ERA of like 0.60 outside of 1 game (8 runs, 0 innings). 2 runs in 30+ innings. He had 35 outings during that stretch and gave up runs in just 2 of them (one being the 8 run trainwreck). Even with the disaster, he had a decent ERA of 3.28 at the ASB. Then he had a few bad outings post-ASB and they went straight to releasing him - I'm curious what the story was there. His overall season numbers aren't great - or even good - and maybe the underlying metrics weren't good, but releasing him seemed extreme. The nice thing if the Astros don't have to pay him anything, they can always take a flier and release him again if it doesn't work out.
