You're in luck. It seems that every player I traded so far this season has done well elsewhere. See: SP Matt Moore.
Anyway, here is my deadline trade block...
SP Manny Banuelos - Get him. He's sure to have success somewhere outside Miami.
RP Tom Wilhelmson - Good strikeout guy, 33 K's in 28 innings pitched. .187 BAA vs RHP
CL Joakim Soria - Having a really good year so far. Could help a contending bullpen. Last year of contract. Remember that his contract is prorated through September (You won't have to pay $6M)
2B/SS Dan Price - Great utility guy. Great Defense. High contact. League Minimum.
SS Miguel Rojas - Great Defense. + Contact/Gap. + Speed. League Minimum.
RF Moises Sierra - On pace for 20+ HR. Above average ability everywhere.
LF Alfredo Silverio - High Contact/Gap/Defense. Currently on the DL for 3 days.
CF Brandon Guyer - Plays all 3 spots well. Above Average at the plate. Currently on the DL for 2 weeks. Batting .290 in 2017
OF Yasuhiko Takeda - League Minimum. Batting .281.
