MASH Report (2/9/15)
• Victor Martinez will miss 4-8 weeks with a torn medial meniscus in his left knee. This puts him getting healthy in the middle of spring training or a couple of weeks into the season.
The Tigers announced Thursday that Martinez has torn the medial meniscus in his left knee. Martinez tore the cartilage last week during workouts in Florida and underwent an MRI and exam on Wednesday in Lakeland, Fla., where the tear became clear.
Looking at V-Mart, he may see a loss of average and power because of the knee injury. Using the spreadsheet linked in this article on how injuries affect production, here is the average loss in production from players with knee injuries.
Rate Stat: < = 30 DL Days, > 30 DL Days
AVG: -.007, -.014
OBP: -.013, -.014
SLG: -.024, -.045
ISO: -.017, -.031
If the injury brings down his projections, he will be closer to his 2013 version (.301/.355/.430) than the 2014 version (.335/.409/.565).
• Josh Hamilton is now less fantasy relevant with surgery on his shoulder which will cost him at least 6-8 weeks.
On Wednesday, 21 days before the first full-squad workout from Arizona, Hamilton underwent surgery to repair the AC joint in his right shoulder, a procedure that is expected to keep him out six to eight weeks and makes him doubtful to be ready by Opening Day.
….
Dipoto called a return by the April 6 opener in Seattle “a little aggressive,” but didn’t rule it out entirely. The likely scenario is that Hamilton starts the season on the disabled list, then returns at some point in April
While I don’t expect much from Hamilton this season, he may be an OK option for a beginning of season DL stash. Just don’t waste anything but a late round pick on him. His production is already down and here is how hitters perform in the season they went on the DL for shoulder issues.
Rate Stat: < = 30 DL Days, > 30 DL Days
AVG: -.014, -.025
OBP: -.011, -.025
SLG: -.029, -.048
ISO: -.015, -.023
• The A’s are looking to have Jarrod Parker and A.J. Griffin back in June.
On Sunday, manager Bob Melvin and assistant general manager David Forst reiterated that June remains a potential timetable for their returns, barring any setbacks.
….
Both Griffin and Parker missed all of 2014 after undergoing Tommy John surgery during Spring Training. Parker was not in attendance at FanFest on Sunday, but Melvin noted they’ll be particularly careful in bringing him back, since this is Parker’s second time through this process.
• For more news on injured A’s pitchers, it seems Sean Doolittle with “not miss a ton of time”.
There is still no timetable for Doolittle’s return but the general consensus seems to be he might not miss a ton of time to start season.

So count Niese among the many Met folks with high hopes for 2015, although he knows there is much to prove, too. Part of the reason for his personal optimism is another winter highlight for Niese — he no longer feels “like there are knives in my (left) shoulder,” he said. “This year it feels normal.” Niese’s shoulder problems were so bothersome last year that, he says now, “I probably should’ve missed the first month of the season.”
I don’t buy for a minute he will be 100% since he had no surgery to fix the problem. Those knives just don’t go away.
• Jose Molina’s career may be close to being over.
• An interesting take from by Frederick Dawes at TheSportInMind on stress leading to more injuries.
Essentially the model proposes that certain psychological factors predispose an athlete to become more stressed when under pressure. This stress response leads to physiological and attentional changes that can increase one’s propensity to injury. The psychological factors included in the model are: personality, history of stressors, and coping resources.
I sort of follow the article’s rational, but I’m not sure how much it could be useful at the fantasy level. It is probably most helpful for a people dealing with the players one-on-one.

Hey Jeff,
Off topic, but is there anywhere public where one can see the edge% stat for pitchers?
Here is the 2009 to 2014 data: https://docs.google.com/spreadsheets/d/1tUG0_0Vtx9fFj2aylSC6KgIoq6QPBFot_X2iUT3uQTY/edit?usp=sharing
As much as I like Doolittle, I just have to believe that shoulder acts up again as some point this season. I hope I am wrong since I love watching the guy pitch and loved owning him last year, but I have little faith he bounces back so easily. Tyler Clippard seems the better bet to own this year or I am I being overly bearish on Doolittle?
I can understand the lack of faith in Doolittle. The key for me is he hasn’t thrown yet, so who knows how long it will be until he returns.
In the Hardball Times article, how did you arrive at the change in OPS figures? I tried adding the “Y-1 to Y+1” numbers for OBP and SLG together, but that is not matching up with the table. Thanks
I a betting you are getting numbers which are lower. I found most of the players on the DL are older and some decline should be expected.
Take players with knees injuries from the spreadsheet. On 30 or less days on the DL, the loss is expected to by 24 points (-.008 OBP and -.016 SLG).
The average age for someone with a knee injury is 30 years old. If you look at the top of the spreadsheet, the normal OPS decline is 39 points (-.011 OBP and -.028 SLG)
So in THT article an increase of 15 points of OPS is shown (injury aging – normal aging).
Does that make sense. For VMart, I am just looking at Y-1 to Y
Thanks Jeff, that makes perfect sense. I see why you didn’t include the aging when referring to Victor since the projections are already taking that into account.
