Darwin Barney's Pacific Coast League (PCL) Sprain
Darwin Barney went on the DL this week spraining "the other" cruciate or Posterior Cruciate knee ligament. I'm sure the Cubs called Iowa Cubs manager Bill Dancy to let him know that his Pacific Coast League (PCL) Iowa team might shortly be getting another middle infielder on rehab assignment for his lineup. Barney sustained the injury to his right knee on the play at home plate on Monday night, scoring the Cubs only run in a 1-0 victory. It looked like he bounced his knee in the dirt during a head first dive and he did stumble a bit getting up from his dive. The MRI showed injury without stretch (grade 1) to his Posterior Cruciate Ligament (PCL). This is considered fairly minor but probably needs to be protected from further injury for about 2-3 weeks.
"As soon as I slid into home plate last night, I knew something was really wrong," he said. "The whole knee went numb. I had an MRI today and it revealed that Grade 1 strain in my knee." (editiorial note: ligament injuries are sprains, muscle injuries are strains)
Right now Darwin Barney can't jump, but you can. So read more after the jump.
There has been plenty of media attention paid to the Anterior Cruciate Ligament (ACL) which when torn in a high performance athlete is treated with reconstructive surgery but little is written about in the media when the posterior cruciate ligament (PCL) is injured. The Posterior Cruciate is structurally the more robust of the two cruciates and isolated PCL injuries can occur but are less frequent and usually produce more subtle symptoms. If both the Anterior and Posterior Cruciates are torn, more drastic instability can occur including knee dislocation but fortunately that is not very common. Most people hear about the fairly common patella (kneecap) dislocation but a true knee dislocation (tibia-femur) is a severe injury and acute knee dislocations can even have nerve and artery damage.
The PCL attaches behind the knee on the tibia and goes to the medial (inner) side of the central notch on the femur. The ligament prevents posterior translation of the tibia relative to the femur above and also provides central rotational stability. Here is an excellent 3D modeling video of the PCL including how the ligament works in flexion and extension of the knee. The Anterior Cruciate (ACL) attaches to the anterior tibial spine near the front of the knee and goes to the lateral (outer) part of the femoral notch. The ligaments cross (hence, cruciate) each other and protect and stabilize the knee when working in tandem from excess rotation and translation.
Before MRI imaging was available, grade 2 vs 3 PCL injuries were sometimes subtle to diagnose on exam with what was called a "posterior sag" sign with the knee extended or a "posterior drawer" sign with the knee flexed. The PCL does image well on MRI studies (see "P" on image), so seeing injury to it (because the tissue signal is altered in injury) is straightforward making even subtle grade 1 injuries possible to diagnose these days.
The most common mechanism of injury is a direct blow to the front of the upper tibia, which is what seemed to happen to Barney's leg in the head first dive at home plate.
Certainly, a grade 1 strain should respond to rest and rehab in a few weeks but when the PCL has a third degree injury and the knee has instability there are arthroscopically assisted surgical reconstructive techniques (see video) available. These have evolved and are significantly improved over the last 2 decades and much of the technology has been based on arthroscopic considerations for the ACL which is now a frequently performed surgery. Brewer ace Yovani Gallardo tore his ACL in May 2008 (against the Cubs avoiding contact with Prince Fielder on a Reed Johnson bunt) and was able to come back to pitch in late September and started a playoff game vs the Phillies that season. The injured PCL has better blood supply than the ACL and therefore can heal without subsequent instability. The PCL is much less frequently reconstructed (than the ACL) and often has several other associated injuries including the ACL and meniscal tears making any associated instability more extensive, so the results are more difficult to assess and should not be compared to the more common anterior cruciate ligament reconstruction outcomes. I don't know of any major league players that have needed PCL reconstruction although I would be interested to hear if any mlb player has had this done.
I wonder if Doc Gryzlo will recommend a few games of rehab in the PCL for Barney's PCL once the swelling and soreness improves.
...why isn't j.lucroy playing for TEX yet?
2r HR on a 12-pitch AB.
nathan to join the cubs tomorrow.
Wow in deed.

Chris Sale was scratched from tonight's scheduled start due to a clubhouse incident before the game
he was sent home by the team, too. the wsox released a press statement and everything. they stated it was non-physical in nature.
He was scratched from his start today. No reason given.
At the start of the season the book was that he was trying to pitch to more contact so he could stay in the game longer and it seems to be working so far. Contact against is 77.5% this year and it was 70.2% the year before. He averaged 6.7 IP/game last year and so far it's 7 IP/game. His actual pitches per game are only down to 106.1/game from 107.2/game last year but if he's able to go a bit farther into games without throwing more pitches and without giving up more runs that is a good thing.
sale's skills and insane value makes it almost too hard to have a market for the guy...he's got 3/38m owed to him over 3 seasons (2 team options). he could easily pull in 30m/yr if he was on the market as a FA.
he's throwing a bit differently this season, especially with more sliders and less changeups like earlier in his career, but all his stuff still looks great even if the HRs are a little elevated and the Ks are down.
Torres, Happ, McKinney, Jimenez, and Candelario for Sale. Deal or no deal?
"The White Sox are reportedly asking for “five top prospects” for Chris Sale, FanRag Sports’ Jon Heyman reports."
Unless he develops 30+ HR power and keeps his walk rate close to his K rate at the MLB level, he's not going to turn into Prince Fielder. And even if he does turn into Prince Fielder, he's gonna have a short prime. His very limited athleticism is likely to also detract some value from his ability to reach base--I don't buy making an out as being preferable to base clogging, but you'd certainly prefer just about any base runner other than Vogelbach, David Ortiz, etc.
seeing as arod has played a total of 27.1 innings of D at 1st/3rd and somehow managed a -0.5 dWAR with his 1 error at 1st and an overall positive total zone rating...he might end up even more in the shitter via the characteristics/flaws/whatever of how some sites determine various WAR values. dWAR doesn't directly lead to a WAR value, but the 2 main entities pushing the most popular variations of WAR sometimes lead to some interesting discrepancies in value.
I have a lot of faith in Baez that he's going to turn into a more consistent, solid player. It looks like it took him about a half season or so of futility at the plate to figure out he was not talented enough to get away with the crazy approach he had. I think his running game will eventually have a more measured aggression.
I hope the D and bullpen show up. Cubs haven't had much luck against Davies, and he's been going well lately. A little uncomfortable with the Cards only 6.5 back--feels like they're right on our tails compared to the 11 game lead I've grown accustomed to.
Cardinals, stop that. Right now.
In a year or two, a lot of fans are going to point at trading him as a mistake. He'll probably be slashing something like 280/400/480 for Seattle at the time. Of course, by WAR, he'll still be worth less than 3, since we're talking zero defensive value.
vogelbomb debut for tacoma (AAA SEA)... 3-3, 1bb, 1 HR, 1 double...DH'd.
while he mostly played 1st considerably more than DH for AAA CHC, DJ Peterson is probably going to see most of the time at 1st for AAA SEA.
Carl Jr.! Very nice!
Baez with another "WTF?" play trying a delayed steal with a runner on 3rd and one out.. Remarkable talent, needs to make better decisions.
