• Good news on the production front from Gerrit Cole. In his last start he struck out three, walked none and allowed no runs. It seems like there are differing opinions on his velocity tough.  Here is a tweet from his last start.

Gerrit Cole has another 1-2-3 inning in 3rd. His velocity was 91-92 consistently, and reached 93 and 94 on a few pitches.

While the team is reporting his velocity to be higher.

As for his velocity? His last pitch of the game was clocked at 95 miles per hour.

“I’m sure there was more in the tank,” Indianapolis manager Dean Treanor said. “That was a good sign.”

Cole’s velocity was consistently in the 95-96 mph range during the first few innings of his rehab start on Tuesday, but dipped to 91-92 mph during the late innings. The dip in velocity was labeled as intentional and ordered by the organization after Cole said he felt “brutal” following his first rehab outing.

“He wasn’t tied down to anything like that (on Sunday),” Treanor said. “What was good when he felt he needed some velocity, he was able to ramp it up a little bit and he had the OK to do that.”

Cole consistently reached 93-94 mph over the final three innings of Sunday’s outing, throwing 73 pitches, 49 for strikes. He was scheduled to throw either 90 pitches or six innings, whichever came first.

At least both were an improvement over his previous start.

Gerrit Cole’s velocity at the end of his rehab outing last night was 91-92 mph. Potential red flag there. #Pirates — Jason Shetler (@Jason_Shetler) August 6, 2014

His 2014 season average before the injury was 95, not a peak of 95 mph. He could be down one to three mph once he returns.

• The Nationals are basically admitting Bryce Harper’s struggles are because his thumb is not yet healed.

He went on the disabled list for two months, and when he came back, he had a new injury that affected his swing. A separate, disquieting notion had taken root, a sense that he was trying to find something that he had lost. “It was like old Bryce right there,” hitting coach Rick Schu said after one batting practice session. “Good to see.”

Hand injuries are hell on hitters – Ryan Zimmerman and Wilson Ramos both suffered power drains when they returned this season. Without full strength in his hand, Harper can make the same swing he always and receive different feedback. You can see why he spiked his helmet at first base after the flyout to the track last night, where the frustration comes from. For so long, the swing he put on that ball would be enough to drive it out of the park. With a left thumb three months removed surgery, it died at the track.

Harper keeps changing his stance and tweaking his swing, but what Harper’s looking for may not be discovered until his thumb strengthens. It is a physical issue that led to shaken confidence that led to mechanical issues.

“I would not discount the fact that he had an injury to his top hand,” Williams said on 106.7 The Fan. “If you don’t feel strong or if you feel something is wrong with your hand, that can affect you. Him coming back from an injury is not easy. If we have a little bit of patience, put in some good hard work, hopefully he gets hot here and he can carry us a little bit, too.”

It seems Harper is heading for a Carlos Gonzalez comp of “Great Talent, but Always Hurt”.

A couple of weeks ago, I released an updated list of hitters and their xBABIP values. After it was released I got a request for the pitcher xBABIP values. The xBABIP values are generated by using the hard hit batted ball data from Inside Edge. I have gone ahead and run the values and listed them below with some comments on a couple starting pitchers.

A few notes on the data. First, I have not tested it with pitchers to see if the data correlates better season-to-season than regular BABIP. I just applied the hitter’s formula to pitchers. Additionally, I used the league average Speed Score in the equation instead of adjusting it for each batter.

• I have had a couple people ask if Adam Wainwright is hurt. Going through some signs, he may just be.

First, he is in the window for needing a second Tommy John surgery after his one in 2011. Here is a description of when a second operation is needed from some of my previous work.

In the 2013 THT Annual, we found pitchers had about 650 innings between their first and second procedure, though the sample size was miniscule. Recently, I ran a brief study using the up-to-date TJS database and found those pitchers who had their first TJS from before 2011 averaged 4.5 years until they needed to go under the knife again, with a median time of 4.0 years. These numbers are in the ballpark of the 650 innings value we originally found.

Thanks to both of you for caring enough about injuries on the trade deadline day to read my article. Well, I here is the latest injury information. Now I need to get back to reading about potential trades.

• James Paxton is an interesting pitcher who should be coming off the DL soon, possibly on Saturday. Before going on the DL, he was putting up some good numbers: 30% K%, 5% BB%, 56% GB% in two starts. According to recent reports from his minor league rehab appearances, his velocity may be down ~2 mph from his early average of 94 mph.

Not much injury news over the weekend, sorry.

• A reader asked if Chris Davis may be injured. The short answer for those with little time, probably. Now here is the long answer.

The concern for Davis centers on his low .199 AVG and 17 home runs. He spent spent 15 days on the DL early in the season for a strained abdomen. No other reported news. Before the injury he hit .250/.372/.382. Since returning, he has mainly  seen a huge drop in his AVG, .183/.288/.394. Looking through my injury indicators, his ISO is down from .240 career average to .192. His Contact% is down for 69% to 67%. These values put his HURT value at 155 which is one of the top values among the league regulars. So, yes his is probably still hurt.

The other issue he is dealing with is the shift. In 2013, he had a .425 BABIP with no shift on and a .302 with the shift employed for a difference of .123. So far this season, he is hitting .375 without the shift on and .236 with a shift for a difference of .141. The shift related decline was almost the same overall for each season. This season he is not hitting the ball as hard (probably from the injury), so both BABIP values are down. I would look at Davis as a possible buy low candidate for next season, but expect the batting average to stay low.

This past offseason, I found an xBABIP equation which correlated better than just BABIP when looking at season 1 to season 2 values . By using the the new Inside Edge data and player speed score, I kept the process  simple yet accurate. I have tweeted out the results a few times during the season, but it is time for another  full updated list.

The Inside Edge data tracks the normal bunts, grounders, fly balls and line drives. In addition to the four groups, they classify the batted ball into weak, medium and hard contract. For the xBABIP equation, I looked at all the line drives and all the hard hit fly balls and grounders. Additionally, speed is a component of getting on base so Bill James’s Speed Score is also added into the calculation.

• In keeper leagues, it is time for the top teams to stabilize their teams with healthy players. This is an opportunity for teams buy low on know health risks. Take Jason Kipnis for example. he has been limited by an oblique injury all year. If a top team has him and you have healthy Ian Kinsler, look to trade for Kipnis. Most owners will do about anything for a win and will take the stability for this season and you get an upgrade for next season. Another player to target is Shin-Soo Choo who has had a bad ankle. Additionally, look over the HURT lists below for more injured players.

Well, I finally got through all the news after a week in New Mexico with my family. No injury prediction reports (PAIN or HURT) today, but will look at publishing them on Thursday (if not before).

• At the Hardball Times, Dan Farnsworth goes into detail on how wrist injuries affect hitters.  Here is his conclusion:

From these case studies, I suspect that hitters who tend to flatten out the bottom hand early and keep it flat through contact put greater strain on their wrist joints. This forces them to use more of their bones and ligaments to stabilize their swings, rather than their muscle mass. Muscles can be strengthened, while bones and other connective tissue cannot. Just like pitchers who are suffering from diminished velocity due to developing elbow instability, I expect hitters with this type of movement pattern to be more likely to suffer downturns in productivity.

Bryce Harper’s production has not be at high level since he has returned from the disabled list. Some people, including his manager, are saying his timing is off. In my opinion, I think his left thumb is not yet 100% for several reasons which is causing his timing issues.

In case someone has not been following the train wreck, here are Harper’s stats before and after the injury:

Before: .289/.352/.422, 23% K%
After: .129/.250/.161, 35% K%

The after is only 37 PA, but the results are abysmal.

To look a little deeper into Harper’s production, here is his batted ball placement before and after the injury (embiggen).

He has yet to hit one ball to the outfield’s right side after the injury. Historically, 81% of his home runs have been to center (30%) or right (51%) field. Since he is hitting nothing to the right side, I expect no substantial power from him.

This situation reminds me of left-handed David Ortiz from a few years back. He hit the ball weakly to left field after a wrist injury and then slowly began to pull the ball with authority to right field  as he got healthy. For a sign Harper is turning it around, look for him to start hitting to right field consistently.

The second key factor telling me the thumb still bothers him is he acts like it does. Players with injuries will physically show signs the body part bothers them. Here is Harper after a foul ball from Wednesday  night.

He concentrates on and re-grips with the injured thumb. I went back a looked at him plate appearances before the injury and he never did anything close to the re-grip. If a Harper owner wants to know if he is healthy, watch a couple of games and see if favors the thumb in any way.

Bryce Harper’s thumb is probably not 100% yet and it is behind his offensive struggles since returning from the DL. Two items can be tracked to see if he is turning his season around. First, look to see if he is beginning to pull the ball with some power. Second, watch some of his at bats and see if he favors the thumb in any way.
