Minnesota Twins
Name: ________________________________
You are the Manager of the Minnesota Twins. You
need to write your lineup for the next week, so you
want to make sure players who are playing well
appear higher in the batting order.
Your Challenge: How should you order your hitters to give
your team the best chance to win?

This data table shows statistics on some of the top Twins players from the 2014 season.

One of the most commonly used statistics in baseball is a player’s batting average. A batting
average is the probability a player will get a hit for each turn at bat.
1.
a.

Calculate each player’s batting average.
Calculate the probability that each player hits a home run if they get a hit.
Calculate the probability that each player hits a home run if they get an at bat.

Do you notice any patterns in the data? Explain your thinking.

You want to make predictions for the next week before deciding your batting order.
3.
You want to decide what your numbers may look like if your players each get 30 at bats in
the next week. Use the probabilities to predict the approximate relative frequency of hits
and home runs for each player. Round your answers to the nearest whole number.

Based on your predictions, would Brian Dozier or Trevor Plouffe have more hits? By how
many more?
5.
On average, a major league player will receive between 24-32 at bats per week.

About how many total at bats will Kurt Suzuki need to reach 10 hits?
Hint: Use his batting average.
About how many total at bats will Joe Mauer need to reach 10 hits?
Do you think reaching 10 hits is achievable within a week?
In your opinion, is it likely that any player will hit more than 2 home runs this week? Why or
why not?
Most managers prefer players with the highest probability of hitting home runs to bat 3rd or 4th in
the batting order. They also prefer players with the highest probability to get a hit to bat 1st or 2nd
in the order.
7.
Based on your research, select a batting order and justify why you believe it is the best
order.

Based on the observed frequencies:
a.
Add up the total at bats, hits, and home runs per player for the four games.

Use the statistics to calculate the same probabilities as Level 1.

Are the probabilities of the outcomes the same as or similar to your predicted probabilities
from Level 1? Why do you think this is?
10.
Based on your data, which players are performing better than you expected? Which
players are performing below expectation? Cite specific evidence to explain your
reasoning.
11.
Do you think you should make a change to your batting order? Justify your decision with
evidence.

Challenge
All hits are not created equal. While some players can hit a lot of home runs, others may thrive at
getting doubles or triples. Total bases is a statistic that managers use to estimate how well a
player is hitting. When calculating the statistic, singles count as 1 base, doubles count as 2, triples
count as 3 and homeruns count as 4.

2.
In the table, determine the number of total bases each player earned.

Based on the data throughout the assignment, rank your batters for the year from most to
least effective. Justify you selection with evidence.

Finale You could give students one of the following finale options or have them choose themselves.
1. Research the other members of the Minnesota Twins to develop a batting order with all of the
hitters. Use this order and statistics from each player to create a promotional flyer for this
weekend’s game.
2. Plan a strategy of stealing more bases in an attempt to score more runs. Research your
players’ stolen base data to decide which players are more likely to succeed. Write an email to
your team’s general manager describing the new strategy and whether or not you feel the team
needs to add more speed.
3. Create a presentation for a pending free agent about your team, telling them about the
statistics for your team and persuade them to sign with you.

Job Background
A Sports Team Manager in this context falls within the category of “Coaches” according to the Bureau of Labor Statistics. Quick Facts: Coaches and Scouts 2012 Median Pay

36,200 What Coaches and Scouts Do Coaches teach amateur or professional athletes the skills they need to succeed at their sport. Scouts look for new players and evaluate their skills and likelihood for success at the college, amateur, or professional level. Many coaches are also involved in scouting. Work Environment Coaches and scouts often work irregular hours, including evenings, weekends, and holidays. Full-­‐time coaches usually work more than 40 hours a week for several months during the sports season. Coaches travel frequently to sporting events. Scouts may be required to travel more extensively when searching for talented athletes. How to Become a Coach or Scout Coaches and scouts typically need a bachelor’s degree. They must also have extensive knowledge of the game. Coaches typically gain this knowledge through their own experiences playing the sport at some level. However, although previous playing experience may be beneficial, it is typically not required for most scouting jobs. Pay The median annual wage for coaches and scouts was $28,360 in May 2012. Job Outlook Employment of coaches and scouts is projected to grow 15 percent from 2012 to 2022, faster than the average for all occupations. Increasing participation in high school and college sports will boost demand for coaches and scouts. Updated February 2015 © NextLesson 2015
