Drinking the Health Potion - Injury Updates for 5/2

In order to make it a more streamlined read, I'll cut down on the analysis and make this a little more bulleted.

Players who were recently put on the DL:

1. Evan Longoria (3B, Rays) - Evan suffered a hamstring injury while sliding into 2nd base on 5/1, he is unfortunately expected to miss the next 6-8 weeks. Keep in mind that hamstring injuries also tend to linger.
2. Michael Pineda (SP, Yankees) - Pineda experienced shoulder tightness during the offseason and started the year on the DL. He was initially expected to make a return to the ballclub sometime in May, but after a further examination involving a dye-contrast MRI, it was discovered that he has a torn labrum and is out for the season. I'd drop him if you had him, except for in keeper leagues.
3. Jason Bay (OF, Mets) - Bay was placed on the DL on 4/24 because he has a non-displaced rib fracture, an injury which he suffered while diving into the wall in left field attempting to make a catch. Although he initially started off slow, Bay was picking it up with the bat before he was injured. I'd expect him to miss an additional week after the minimum stint.
4. Daniel Hudson (SP, Diamondbacks) - Hudson was placed on the 15 day DL with a "shoulder impingement" on 4/21, and has been told to wait until at least May 8th to begin throwing again. The club indicated that he'd need at least 2 rehab starts, so I'd expect to not see him until the end of May/early June.
5. Ryan Zimmerman (3B, Nationals) - Zimmerman was placed on the 15 day DL on 4/27 after he experienced some "shoulder tightness" which was causing him issues with swinging the bat. He is looking to be activated for 5/6, as soon as he is eligible.

Updates on existing injuries:

1. Kyle Farnsworth (RP, Rays) - In a relatively unexpected move which is great for Fernando Rodney owners, the Rays moved Farnsworth from the 15 to 60 day DL, Don't expect to see Farnsworth until at least the all-star break. With the turmoil of the Rays closer position I'd stay away from this if at all possible.
2. Ryan Howard (1B, Phillies) - Howard was recently cleared to begin baseball activities again on 4/28. Although he isn't expected to begin swinging a bat for the next few days, he's allowed to take grounders and begin moving around more now. Expect a late May/early June return.
3. Drew Storen (RP, Nationals) - Storen has begun to move his arm freely and expects to start being allowed to throw within the next few days. No timetable has been updated for him, but most injury experts expect him to return prior to the all-star break.
4. Lance Berkman (1B/OF, Cardinals) - Berkman has been on the DL with an injured calf muscle which he attempted to play through and then re-aggravated. He hasn't begun a rehab assignment or ran on it since. I'd expect a late May return.
5. Brett Gardner (OF, Yankees) - Although Gardner was initially only expected to make the minimum stint on the DL, it appears that the Yankees are going to push for him to play in a few rehab games prior to coming back. I'd expect to see him early next week (5/8 or so)
6. Doug Fister (SP, Tigers) - Fister has been sidelined since his first start in April with a rib muscle strain. The Tigers are planning on him coming back to make his first start on 5/7.
7. Ryan Dempster (SP, Cubs) - Dempster will return to the normal rotation on 5/3
8. Carlos Quentin (OF, Padres) - Quentin hasn't played a game yet so far this year after going on the DL in the off-season to recover from knee-surgery. He's expected to start a rehab assignment at AAA on 5/3 and is expected to spend at least a week there. I'd guess for a 5/14 callup.
9. Chase Utley (2B, Phillies) - Expect Utley to finally get called up sometime during next week after spending a week getting some AB's in the minors.
10. Chris Carpenter (SP, Cardinals) - All quiet on the western front, unfortunately. Carpenter says that his arm feels better but doesn't have a projected date to start rehabbing, let alone come back for a rehab assignment. Expect him to return after the all-star break. 
11. Michael Morse (1B/OF, Nationals) - Morse has been the source of much frustration for managers who drafted him. After only expected to miss a week or two, he suffered a setback and is now targeting a June 1st return date. 
12. Carl Crawford (OF, Red Sox) - After starting his rehab, Crawford's elbow flared up again and he was recently diagnosed by the famous fantasy doctor of death (James Andrews) as having a sprained ulnar ligament. He's supposed to miss an additional 3 months and won't return until August at the earliest. You may want to consider dropping him all-out in non-keeper leagues.
13. Cliff Lee (SP, Phillies) - Lee's oblique will keep him sidelined at least another week. He isn't supposed to currently go on a rehab assignment, but throw bullpen sessions instead. Look for another 2 weeks, so returning around 5/15 or so.
14. Jacoby Ellsbury (OF, Red Sox) - Expect Ellsbury to miss at least the next 6-8 weeks with his shoulder sprain from his collision at 2nd base. 

Good luck to everyone this week !
