Both Luis Vizcaino and Luiz Ayala should clear waivers soon if they haven't already. So if TX is in on either of these guys we should know shortly. If Ayala is claimed off waivers, he will likely be traded to said team for a prospect or PTBNL.
I would be very interested in Ayala and only interested in Vizcaino if he accepts a minor league contract to work out his issues with his FB: he is only throwing it about 40% of the time even though he still shows good velo.
Brendan Donnelly was also just granted his release from the Astros today so he is a FA. He had some nice #s for their AAA affiliate and would be worth a minor league contact in my estimation: 24 games 6 saves 1.65 era 25.2ip 21h 5er ohr 7bb 23so
