Why Pujols returned so fast; Lester on DL

It's that time of the week when your mailbag and Twitter questions drive the blog. Thanks once again for your thoughts and insights. Many of you have questions about St. Louis Cardinals first baseman Albert Pujols and his quick-to-heal forearm fracture. This is a great reminder that not all injuries are created equal, that time frames for return to play should always be looked at as guidelines and that everyone heals at different rates.

Pujols suffered a fracture of his left distal radius (the tip of the forearm bone on the thumb side, just above the small carpal bones of the wrist). While it involved the wrist area, it was not an injury specifically within the joint, making it a much less complex problem. It was reported as a hairline crack, small and difficult to see initially on imaging. The bone was not completely broken in two (or more) pieces and it was nondisplaced, meaning everything remained in good alignment. These elements contributed to the potential for the bone to efficiently repair itself.

There were many reports that Pujols had a significant decrease in pain and demonstrated excellent grip strength the day after the injury. While his forearm and wrist were splinted to allow the bone to heal, he quickly resumed a weight lifting workout program and really never lost much in terms of overall strength and fitness. Signals of early healing in the bone and his lack of discomfort allowed the team to progress him fairly quickly to swinging a bat. When that did not reproduce any symptoms, he then began to swing against increasing contact. The fact he was able to move fairly quickly through a progression while the bone was healing meant that he lost very little when it came to the mechanics of baseball; the feel of gripping the bat, the timing of his swings, even the return to fielding ground balls. Hence the team felt no need to send him on a rehab assignment but instead chose to return him to the games as soon as healing had progressed to the satisfaction of the team physician.

A different fracture -- of slightly different dimensions or in a slightly different location -- on a different person might well have required at least four weeks in a splint before returning to activity. The time frame initially issued was reasonable; Pujols, in addition to being a great athlete who is in excellent shape, happened to have everything proceed exceptionally well. Remember, this is the same athlete who had an injury to his ulnar collateral ligament, which many believed would require Tommy John surgery. Although he has undergone two lesser elbow procedures -- to address spurs and to transpose (move) the ulnar nerve -- Pujols has continued to play effectively without reconstructing his elbow.

Short of falling with his full weight on to his outstretched glove hand (or reproducing the exact injury of a runner colliding with his glove), the risk of reinjury is low, just as the risk of having the injury happen in the first place was low. Pujols was sporting a supportive wrap Tuesday and will continue to do so for some time. The medical staff will be looking for feedback from Pujols as to how he feels after his first start Wednesday, whether he is sore the next day and whether any adjustments will need to be made. Whether he can hit with full power remains to be seen, but so far in the practice swings he has taken, there is nothing to suggest he will be compromised. The downtime, which normally compounds the degree to which players struggle at the plate when returning from hand, wrist and forearm injuries, was so brief that it is not likely to be a factor for Pujols. As I noted when the injury happened -- and perhaps even more evident now -- for Pujols and the Cardinals, this injury could have been far worse.

Thanks to Twitter users @ieeewok, @MOanimalcracker, @todd13, @breeleighjo, @loqiel, @JoshX1993 for all the Pujols questions.

Moving on to other players of interest. If you don't see your question answered here, it could appear on the 06010 Fantasy Focus podcast, so stay tuned.

Wayne Jensen. Lincoln, Neb.: How soon will Ryan Braun play? How bad is his injury?

Braun is dealing with a reported mild left calf strain, but after being out of the lineup four consecutive days, the Milwaukee Brewers decided to send him for further workup. Braun was scheduled to undergo an MRI on Wednesday as part of the evaluation. We know calf injuries can take longer to resolve than the athlete expects (Exhibit A: Derek Jeter), but trying to put a timetable on them can be difficult. Right now, there is no good answer to your questions and Braun's status has been a day-to-day evaluation so far. He's been selected for the All-Star Game, but if he's not back playing for his team this weekend, playing Tuesday could be in jeopardy as well. So far, there's been no overt discussion of a DL stint, but the outcome of Wednesday's visits could influence that.

@vtbasser: Left lat strain for Jon Lester. Help a Red Sox fan out, what does it mean?!

@swk473: Lester, how long are we talking?

Lester underwent further evaluation Wednesday, including an MRI, for the latissimus dorsi strain that forced him to leave a no-hitter after four innings, and the Boston Red Sox have placed him on the 15-day DL. Although manager Terry Francona has not commented on the specifics of the test results, any time there is an injury to a muscle that contributes significantly to a pitcher's throwing action there is reason to be concerned. But as with any injury, the impact really rests in appreciating the severity. Consequently there isn't a ton to offer in terms of specifics just yet when it comes to how long we should anticipate Lester's absence to be. A mild strain might allow him to return within a couple of weeks. More severe "lat" strains can cost pitchers a month or more. Gordon Edes, who covers the Red Sox for ESPN Boston, nicely laid out the range of DL days for several pitchers who have recently sustained this injury and why it is problematic. The fact that Lester came out of a game in which he was pitching so well hints at him recognizing this was not something to push. Glass-half-full reaction: He recognized it early before it had a chance to become something that will linger. Glass-half-empty reaction: If a guy comes out of a no-hit bid, he probably is feeling more than just a little soreness. We will see how Lester progresses over the next two weeks, but fantasy owners should be prepared in the event that this extends beyond two missed starts.

@LA_Frankie: Scott Baker, tender elbow. Please discuss how bad it might be, or if they were just playing it safe.

Baker was another pitcher who left his Tuesday start early because of discomfort, but his was in his throwing (right) elbow, more concerning given that this elbow gave him trouble last year. According to 1500 ESPN Twin Cities, Baker was scheduled to undergo an MRI on Wednesday but the team was referring to the injury as a mild elbow strain. Baker said after the game that he contemplated saying nothing to the medical staff and attempting to pitch through it, but then acknowledged, "... it just was a little more discomfort then I would have liked to continue to pitch with." He described the discomfort as feeling "more muscular than anything" and emphasized that he was trying to be proactive. "At this point in the season I'm just trying to be smart about it," Baker said. Given the collective injuries the Minnesota Twins have suffered, and Baker's own history of tendinitis near his elbow, it goes without saying that he made the correct decision.

The Twins may be playing it safe, but who could blame them? Most elbow injuries are a result of collective overuse. While some wear and tear is expected as a natural consequence of pitching, one thing we know from biomechanical studies done at the American Sports Medicine Institute in Birmingham, Ala., is that when pitchers alter their mechanics (which can result from fatigue or injury), the forces across the shoulder and elbow can change dramatically, resulting in far greater consequences. People are learning that it is often better for pitchers to back off and rest -- even when an issue appears minor -- than to try to force through it and risk something catastrophic.
