Mat Latos (elbow) will throw a bullpen session Friday. It's obviously a good sign, and Latos should be able to get back on track quickly if he can get through the 'pen session with no issues. The right-hander had to be scratched from what was supposed to be his final rehab start due to a sore elbow earlier this week, so he conceivably still might only need one more rehab outing provided he's healthy.
