Vic Black is definitely worth a flier if he's healthy, as he has past success in the majors and throws 95+. Blake Wood is another 95+ arm with major league experience who I'd consider.
I don't know much about him, but former Jays farmhand Robert Zarate came out of nowhere to put up great numbers as a lefty swingman in AAA Durham last year. He's pitching in Venezuela right now, maybe worth a look.
On the position player side, former top prospect Sebastian Valle is just 25 and had a breakthrough season with the bat last year, so I'd like to see if that is real. I'd also like to bring back Kenny Wilson, as on-base skills and strong CF defense is always useful in AAA.
