Just FYI....Baseball Trade Values is now a paid site but each week they will provide two teams player/prospect SV for free. This week it's the White Sox and Padres, so this is what they have right now for various players on the ML roster that might be trade bait (my comments in parentheses):
Banks 9.5 (not bad at all)
Brebbia -2.2
Clevinger 2.5 (I thought it would be zero)
Colas 6.6
Crochet 61.2 (sell high ASAP!!!!!!)
DeJong 2.1
Fedde 11.9 (I was hoping it would be higher than this...but maybe if u package him with Banks, you can still get a pretty good 20m SV prospect out of it)
Flexen 2.2 (I'm shocked by this, with his small salary I was hoping for way more, hes pitched very well recently)
T. Hill -1.1
Julks 8
Kopech -1.8 (sigh)
N..Lopez 1.4
Pham 3.1 (was hoping for more)
Robert 44.7 (apologies to @CaliSoxFanViaSWside, seems he was right on how much value Robert has lost, 44m SV is basically what we got back for Cease and that's very light to me, I think Robert's SV last year was something like 77m, so he's lost alot of helium. I wouldn't trade him for 44m, maybe hope he has a great second half and we can hopefully get more in the offseason).
Sheets 3.9
Soroka -1.8
Vaughn -0.3 (lulz)
S. Wilson 0.7 (the idea or getting him from SD to flip him was a good one,didn't work out it seems)
