Comparison of prediction methods for batter-pitcher matchups
No full textBaseball is full of confrontations and these confrontations between a batter and the pitcher is what makes the game. If a formula would be able to predict the probability of the outcome correctly, when they meet, wouldn’t it instill confidence in the minds of the head coach (or you if you are playing the fantasy) to select someone who would be on the winning end? We would like to know for sure, which of our batters are good, and what out of the small amount of possible outcomes, will be the result when he faces this other good pitcher from the team you face next. It seems the past performance of the batter against this pitcher can be a good indicator, and that is what presumably the methods currently used utilize. But the utility of the Batter vs. Pitcher data in predicting the future outcome is a debate going on for quite a time now. The reason for this debate stems from the fact that the sample size of this data is so small that it becomes hard to comprehend when to prefer information you get from a sample size of thousands of atbats against all pitchers vs. maybe a few dozen against specific individuals. The report will discuss one of the famous methods, called Log5 [1] that has been utilized so far when it comes to measuring the outcomes of these confrontations. It also discusses the other methods like logistic regression based on the past data and the new and upcoming Morey-Z. [3]Mechanical Engineerin
Establishing the elbow load and the within-pitcher load variability during a baseball pitch in relation to the ball speed
No full textUlnar collateral ligament (UCL) injuries are common in baseball pitching. The elbow external valgus torque is assumed to be indicative for the applied load on the UCL. This study investigated the maximum external valgus and extension torque and their corresponding load variability during a baseball pitch and the relationship between the magnitude and the within-pitcher load variability of these elbow torques. Furthermore, this study investigated to what extend the elbow torques and the ball speed are related. Eleven Dutch AAA pitchers each threw 25 fastballs. The motion was captured with an optical motion capture system. The ball speed was measured with a radar gun. The data of the upper body, in particular the elbow torques, were analysed using a custom-made 3D inverse dynamics model. The results show that the within-pitcher load variability differs among pitchers. A higher applied elbow torque compared to other pitchers indicates a higher within-pitcher variability. From these results, both a higher valgus torque and a higher within-pitcher load variability are expected to lead to higher injury risk. It is advised not to take one pitch per pitcher into account since it cannot represent all the pitches, especially if only the fastest is selected. Among the pitchers, ball speed is found not to be a good indicator for the elbow torques. Within a pitcher, the ball speed serves better as an indicator. This study emphasises the importance of analysing each pitcher’s results individually instead of comparing them to the whole group.Biomedical Engineerin
Aquatic insect populations in transplanted and natural populations of the purple pitcher plant, Sarracenia purpurea, on Prince Edward Island, Canada
No full textIn early July 1991, 234 pitcher plants (Sarracenia pulpurea) were transplanted from a Prince Edward Island bog being mined for peat into three bogs that varied with respect to previous pitcher plant abundance. One bog had a thriving natural pitcher plant population prior to transplant, while the other two had fewer than three pitcher plants. Between mid-June and late August 1993, abundances of the pitcher plant inquilines Wyeomyia smithii (Diptera: Culicidae), Metriocnemus knabi (Diptera: Chironomidae) and an unidentified sarcophagid fly (Diptera: Sarcophagidae) from transplant bogs were compared with remaining populations in die source bog and with other natural populations. Of the three inquilines, W. smithii was the most severely affected by transplant; it was extremely rare or absent in transplanted pitchers, although it was found in all other bogs investigated on Prince Edward Island. Metriocnemus knabi larvae were common in ail bogs investigated, except for those transplant bogs where pitcher plants were rare prior to transplant. Sarcophagid larvae were found in all of the bogs sampled, and were apparently unaffected by transplant. Desiccation during the transplant process, as well as the time of the transplant, may play a role in the success of recolonization of the pitcher plants after transplanting.PT: J; CR: ADDICOTT JF, 1974, ECOLOGY, V55, P475 BRADSHAW WE, 1984, AM MIDL NAT, V112, P294 CAMERON CJ, 1977, CAN J ZOOL, V55, P2018 ELLIOTT JM, 1977, FRESHWATER BIOL ASS, V25 FAIRCHILD WL, 1987, CAN ENTOMOL, V119, P647 FARKAS MJ, 1986, CAN ENTOMOL, V118, P1307 FARKAS MJ, 1986, CAN J ZOOL, V64, P285 FISH D, 1978, AM MIDL NAT, V99, P172 FORSYTH AB, 1975, CAN J ZOOL, V53, P174 GIVNISH TJ, 1989, PLANT ANIMAL INTERAC, P243 HEARD SB, 1994, ECOLOGY, V75, P1647 HEARD SB, 1994, ENVIRON ENTOMOL, V23, P1250 ISTOCK CA, 1975, EVOLUTION, V29, P296 ISTOCK CA, 1983, PHYTOTELMATA TERREST, P191 JUNIPER BE, 1989, CARNIVOROUS PLANTS MOGI M, 1980, TROPICAL MED, V22, P1 MOORE PD, 1974, PEATLANDS NASTASE AJ, 1991, AM MIDL NAT, V125, P356 NASTASE AJ, 1995, AM MIDL NAT, V133, P44 PATERSON CG, 1982, CAN J ZOOL, V60, P3075 SCHNELL DE, 1976, CARNIVOROUS PLANTS U WALLIS RC, 1967, MOSQ NEWS, V27, P9; NR: 22; TC: 5; J9: CAN J ZOOL; PG: 8; GA: VQ081Source type: Electronic(1
A Training and Conditioning Program for the High School Baseball Pitcher

Population Growth of the Pitcher Plant, Sarracenia Purprea L., at Cranberry Bog, Licking County, Ohio
No full textAuthor Institution: Department of Botany, University of IllinoisA population of the pitcher plant, Sarracenia purpurea L., at Cranberry Bog Nature Preserve, Licking County, Ohio, was founded by a single individual transplanted to the bog in 1912. From an observation of the population in 1921, the intrinsic rate of increase for this population was estimated to be between .0016 and .0023 per day. A recent survey of the present size of the population revealed approximately 157,000 pitcher plants. These observations suggest that the population has not only reached the carrying capacity of Cranberry Bog, but that it did so as early as 1942. Comparisons between the intrinsic rate of increase for S. purpurea and the few other plant species that have been studied suggest that pitcher plants have a relatively slow rate of population increase for an herbaceous species

A Markov Approach to Modeling Baseball At-Bats and Evaluating Pitcher Decision-Making and Performance
No full textThe author models baseball at-bats using absorbing Markov chains, formed based on pitch-by-pitch data for 90 pitchers from the 2015 season. These matrices are used to reverse-predict performance statistics that compare closely to actual values for these pitchers. The author finds that Markov chains are well-suited to model at-bats because they illuminate differences in pitching style and effectiveness and explain performance changes over time. After showing that Markov matrices provide a reasonable model, the author uses this model to examine the effectiveness of two traditional baseball strategies — a batter taking, or not swinging at, the first pitch of an at-bat, and a pitcher intentionally throwing a ball on an (0,2) count — and, more generally, to examine how pitchers could optimize their performance by making better decisions. The results show that taking the first pitch is significantly more effective against weaker pitchers, while the (0,2) waste pitch is generally more effective for strikeout pitchers than contact pitchers, but the difference is not significant. In addition, this thesis highlights the importance of “the count” in baseball and finds that pitcher performance is largely predictable based on the manner in which the count progresses in an average at-bat against him

Beer, Brats, Cheese, and-- Baseball: The History and Impact of Baseball in Wisconsin
No full textFrom the 1800s baseball became a passion for the citizens of the United States. Wars, recessions and scandals could not bring down what is known as "America's Pastime." However baseball and other professional sports have been getting a bad name since historians and economist have started to look at the correlation between the team and the community. The notion of, "build us a new stadium at the cost of the tax payers or we are taking our team elsewhere" has been a common trend since 1950's. By looking at Appleton and Milwaukee this paper will look at the impacts baseball has on these communities both culturally and economically from 1966 to 2012
