Wainwright (abdomen) threw a bullpen session Monday, CBS Sports' Jon Heyman reports. He was only expected to miss a few days after suffering an abdominal strain last week and that ended up being the case. Wainwright is already going at a pretty fair discount in drafts based on the concerns surrounding the abdomen, but more notably the elbow issue he dealt with at the end of last season. It will be interesting to see how he progresses this spring against live hitters.
