Sample Size and Spring

I love this site. Thanks guys! I enjoy reading the thoughts and projections for the opening roster. However, I cringe every time I see anyone use spring data in support of a player making a roster.   All winter long, I listened to Gleeman and the Geek remind me that Parmelee's 86 plate appeaeances last fall were not predictive of the future. They are essentially correct. There have been some significant studies about sample size and at that size we might start learning something about contact ra

Revisiting Catching and Defense

My last blog topic on catcher defense was last November. The trade of Butera has prompted a revisit.   Through July 26 while Ryan Doumit was catching, 46 out of zone balls were called strikes and 205 in zone strikes were called balls. They convert it to a ratio which for Doumit would be 0.22 extra strikes/lost strikes. That ratio is the worst in baseball and the next for a current catcher is twice the ratio at 0.44. The data is from Baseball Prospectus.   How much difference does that make in te

Replacing Santana

As Ervin Santana gets ready for his first start in Rochester, I wondered what the impact of his loss has been on the Twins thus far. Mike Pelfrey was his immediate replacement and he has certainly stepped up to the task. He has far outperformed what we might have expected from Santana. It isn't really fair to compare his performance to just Pelfrey though.   I looked at the performance of Pelfrey, May and Milone. All three had opportunities that may not have been available had Santana not let do

Rebuilding a Bullpen

The Twins bullpen has the poorest strike out rate in the majors. This is not a surprise and was projected when the 25 man roster was announced. The Twins may need to trade for bullpen help at the deadline. Before that happens, I hope they look at solutions internally.   The Twins need at most one LOOGY as opposed to the two they are using now.   These pitchers are possible internal solutions. The split rates are since 2011 unless otherwise specified. That allows a large enough sample in taking a

Projecting the Twins: Early 2013 ZIPS

The early ZIPS projections were reported midweek and the AL Central has sobering information for the Twins.   http://insider.espn.go.com/mlb/hotstove12/story/_/id/8599684/projecting-american-league-central-players-teams-2013-mlb   Note: Unfortunately, you will need an insider account to access the link above.   The Twins in their construction are projected for 66 wins and 5th place in the AL Central. Entering the 2012 season they had a projected 70 win team from ZIPS so in the ZIPS lens the Twi

Priorities: The Best Backup Catcher in Baseball

The Twins are a team of many needs.   Doumit fills the need of back up catcher and emergency RF. He hits well for a catcher, but at best adequately for a DH or RF. He doesn't defend well at either spot. As he declines, his best role will be back up catcher and pinch hitter. He will do that job well. He will be a good guy in the club house.   Essentially by signing him now, they have begun the winter process of rebuilding this team through free agency. Is this the best first step? Is this one of

Platoon Advantage

Two topics that appeared in the forums led me to wonder which teams are getting the platoon advantage.   How did the Indians do it? I look at their numbers and see a combined 6.1 WAR from Jan Gomes and Ryan Raburn. Those cheap additions will be the difference between contending for the wild card and being on the fringe. Francona has found a role for them to put up fantastic numbers.   We also debated about how platooning might help the Twins.   I wondered how often teams are getting the platoon

Nick Gordon, Lamonte Wade and Infield Fly Balls

I am curious about the vast difference in infield fly ball percentage in Nick Gordon and Lamonte Wade and wonder how much it matters projecting their bats as major league hitters. I was able to find a few articles on IFFB% but those authors leave wondering also.   One claim is that players with a lower IFFB rate tend to post higher BABIPs.   Another claim is that minor league IFFB rates are greater than major league rates. A wonder is whether this is selection bias and those with greater IFFB ra

Maybe there was some risk...

With the signings of Kubel, Bartlett and Guerrier, comments overwhelmingly went like these below.                 No risk? No impact on the 40 man roster?   Alex Presley Brooks Raley Darin Mastroianni   Signing decline phase players (even to minor league contracts) does have a risk.   It kept the Twins from seeking other younger solutions.   It invests playing time into players with no upside.   It costs a few younger players on the 40 man roster who have a better long term shot at being a role

Looking at the 40 man roster

With the depth of the Twins system, they will have several players that need to be put on the 40 man roster this winter to avoid the rule 5 draft. Are there so many that the Twins should consider trading some of them this summer? How many spots will reasonably be available this winter?   With the DFA of Tim Stauffer, the Twins currently have 40 men on their 40 man roster. There is one spot available as Ervin Santana will not count until he return in July.   The Twins will have some players ente

Landa and Rosario: The Clock is Ticking

The Twins chose to add Yorman Landa and Randy Rosario to the 40 man roster. There is no doubt they have major league velocity. They also haven't found success in Low A ball yet. They opened in Cedar Rapids in 2014 and were injured early in the season. Last year both returned from injuries and pitched in rookie ball before entering low A in 2015.   They need a career path where they can be established in the majors before they run out of options   2016- They really should start in Cedar Rapids ag

Kurt Suzuki - Signed to be the starter?

Mike Berardino reported yesterday that Terry Ryan expected Kurt Suzuki to start at catcher. At the time of the signing, it appeared that Suzuki was signed to gibe the Twins a veteran backup. On this site, there were certainly questions about his defense and concern about the workload he carried early in his career. At the time, the best available options other than Suzuki were John Buck or retaining Doumit. While Suzuki has shown to be a poor pitch framer, Doumit and Buck are at the bottom.   P

Jordan Schafer: Breakout or Bust

Jordan Schafer is at his 4th stop having moved from Atlanta to Houston to Atlanta prior to being claimed by Minnesota. He enters next season as a 28 year old with a significant 1398 plate appearances. Is there a chance that the once highly rated prospect can turn it around at age 28? Has it happened before?   I used Baseball Reference's play index seeking an answer. I wanted a group of outfielders that had a similar number of plate appearances and performance through age 27. A group where Schafe

Gambling on the Relief Market: Simply Folly

Signing relievers to multi-year free agent deals is a risky proposition.   Dave Cameron had these numbers in a study from 2010.   I wondered if anything had changed since the study and the new free agency rules. There were 11 non-closer relievers signed prior to the 2013 season to multi year deals.   Jeremy Affeldt (2013-2015), 3 years, $18 million: $-6.6 million(Fangraphs) Mike Adams (2013-2014), 2 years, $12 million: $0.1 million(Fangraphs) Jason Grilli (2013-2014), 2 years, $6.75 million: $1

Framing By Battery

Baseball Prospectus has pitch framing data organized by battery.   Framing data by battery   The data looks at pitches where the umpire needs to make the call and compares actual strikes with predicted strikes. While looking at splits creates small sample sizes, I wondered if it would be clear that Josmil Pinto's framing skills are significantly worse than Kurt Suzuki.   The natural place to start is Glenn Perkins.   Chances Predicted Actual +/- Josmil Pint

FIP. Fielding Independent. Really?

Fielding Independent Pitching (FIP) measures what a player’s ERA should have looked like over a given time period, assuming that performance on balls in play and timing were league average. Fangraphs relies on FIP to calculate WAR for pitchers.   Is FIP independent of the catcher?   The following table shows pitching performance by catcher over the last two seasons.   [TABLE=width: 500] Catcher Inn K/BB FIP Joe Mauer 1286 2.32 4.32 Ryan Doumit 865 1.65 4.78 Drew Butera 307 2.53 3.80 C

Extending into the 30s

What do the Twins do about Plouffe and Dozier? Extend? Go year to year? Hope to sell high at 30?   There has been some great discussion started by Seth on Dozier and Plouffe.   There also have been studies that show aging curves in the post steroid era are changing. Fewer players are maintaining their peak seasons into their thirties. There are many studies to read. Here is one by Jeff Zimmerman for Fangraphs.   I wondered how players currently around 33 years old have aged. With the help of pla

Expect Growing Pains

I am excited to see Chris Parmelee this year. I look forward to seeing Joe Benson and Brian Dozier. I want to see how Trevor Plouffe and Ben Revere progress. I also know they are not ready. At some point this season someone will have written, they called him up to soon because they weren't ready.   The reality is that very few are ready. Most cannot get ready for the majors without struggle at the level first. So expect the struggle. Be patient. The plate appearances invested this year will lik

Dozier - What Difference Does It Make?

I tried to study the impact of the batting order change using ZIPS projections. I was a little disappointed in the results.   I used the average plate appearances by batting order position in the AL last year. The second spot had 103 more plate appearances on average than the 8th spot. That made sense as it is close to 6x18.   I then compared a Dozier with 735 plate appearances to a Dozier with 632 plate appearances. (Yes... I know he is not going to play 162 games and neither are any of the oth

Doumit, Molina and Pitch f/x

"I don’t say this about many decisions, but starting Doumit at catcher might be a fireable offense. In 60 games at catcher for Pittsburgh in 2011, his framing cost the Pirates 20 runs. In 59 games for Minnesota in 2012, his framing cost the Twins 21 runs. All told, his framing has subtracted 98 runs over the past five seasons, on top of the damage from the other things he does poorly behind the plate, which wipes out his offensive value."   Ben Lindbergh, Baseball Prospectus   Read the article a

Don McCormack, Tino Martinez, Lance Lynn and the 75th Pick

Note: Thanks to spycake, I know now that we will forfeit pick 95. Even better. Only 2 players of 53 with significant careers. Amos Otis and Dave Cash. Addison Reed and his 6.8 WAR checks in as the third most successful pick 95.   What is the 75th pick in the draft worth? If the Twins sign Alex Cobb or Lance Lynn they would forfeit this pick. How much should this loss factor into the decision?   With the help of baseball reference, I took a look at all of the pick 75s since 1965. The very first p

Developing Yordano Ventura

The Twins have been notoriously slow at moving pitchers through the system while they wait for consistency. I thought it might be interesting to see how some of other young pitchers moved through their systems. How about Yordano Ventura? Yordano Ventura and Alex Meyer both pitched in the Carolina League in 2012. Meyer started in low-A and arrived about the time Ventura was leaving. What was the Royals plan for Ventura? Did they wait for consistency?   2010- He started the year in the Dominican s

Buying High

Terry Ryan has had success finding bargains in winter free agency. Kurt Suzuki was an all star. Jared Burton was a top set up man. Ryan Doumit provided a very good bat. In all three cases, the Twins chose to extend into their thirties rather than sell. It is not possible to know what the offers could have been for those players. They were all performing well enough to be valued by other teams and there would have been offers. All three could point to some aspect of their games or health that had

Burton: What's is the Future for a 31 Year Old Set Up Man?

I was surprised at the suggestion earlier that the Twins should consider extending Burton. They have him locked up next year. In two years he will be 33. On the other hand, he has been very valuable this year.   My first thought was it was a horrible idea. Take his season next year at the bargain level. Don't buy his 33 year old season now! That was clearly the minority opinion.   I went to Baseball Reference for clarity. I searched for every season pitched by a 31 year old set up man from 2000-
