Sergio Santos threw again today, but there's still no timetable.
Brandon Morrow threw a nice bullpen today. It says in that link that it's too early to speculate, but I don't imagine he'll be back until at least the start August. Wilner said in a tweet that Morrow will probably need 5 rehab starts in the minors to stretch out.
Jon Morosi of FOX says that the Jays are more interested in upgrades for the rotation than for the bullpen, but both are on the docket.
The Jays have selected the contract of Aaron Loup from AA New Hampshire, and they placed Luis Perez on the 15-day DL. Loup is a few weeks younger than I am, and was chosen in the 9th round in 2009. He has a 2.78 ERA over 45 innings in New Hampshire so far this year, striking out almost a batter an inning.
