The Cubs have claimed 26-year old RHP Dylan Floro off waivers from the Tampa Bay Rays.
Tampa Bay's 2012 13th round draft pick out of Cal State - Fullerton, Floro spent most of his pro career in the minors as a starting pitcher before moving to the bullpen at AAA Durham in 2016. He made his MLB debut last July and spent 40 days with the Rays (4.20 ERA and 1.87 WHIP in 15.0 IP and 12 games), before being optioned back to Durham in August. He was Designated for Assignment by the Rays last Wednesday.
Floro is an extreme ground-ball pitcher and strike-throwing machine (allowing just 9 BB in 50 IP at AAA in 2016) who features a 92-93 MPH sinker and 86-88 MPH cutter/slider combo, and he will likely provide depth as a SP/RP "swing-man" at AAA Iowa in 2017.
The Cubs MLB Reserve List (40-man roster) now stands at 39 (one slot is open), although it is possible that the Cubs will try and outright Floro to the minors right away (once waivers can be secured) since the Cubs have the #30 (last) waiver claim priority and no other MLB club was interested enough in Floro to make a claim. (Floro cannot refuse an Outright Assignment to the minors, and if outrighted he would not be eligible to be a minor league 6YFA until after the 2018 season).
