Baltimore: Waverly Press, 1971.  First edition.

Follow-up to Cook's 1964 Percentage Baseball, an early assessment of using statistical methods to optimize baseball outcomes.  Forerunner to Bill James' sabermetrics and Moneyball.

Signed and dated by the author.

Toning to front and rear pastedowns and free endpapers.  Near fine without dust wrapper as issued.

Cook set out "to prove, once and for all, damn it, that Ty Cobb was better than Babe Ruth...everyone agreed that a home run was more valuable than a single, but by how much? To what extent did stolen bases and the venerable sacrifice aid in the scoring of runs? Come to think of it, what was the optimal lineup order? How should relief pitchers be used? Cook didn't want to go "by the book," blindly accepting the time-honored answers to these questions -- so he wrote a book of his own. In fits and starts over several years, Cook holed up in his study, overlooking the golf course, and pounded on baseball statistics. His slide rule and colored pencils stood at attention above his angled drafting table, piles of The Sporting News and its "Baseball Register" at the ready.  

Sports Illustrated [writer] Frank Deford learned of this quirky baseball scientist and mentioned him to his editor, who dispatched the young writer to interview Cook during the winter of 1964. The editor liked the piece so much he made it the lead feature story of the March 23 issue, with the headline 'BASEBALL IS PLAYED ALL WRONG.'..

Cook's rigorous mathematics ultimately failed him on both ends of the reader spectrum. Baseball fans were spooked by the intercept coefficients, distribution curves, and bizarre graphical techniques that recalled too many failed algebra quizzes. Professional statisticians, meanwhile, accused "Percentage Baseball" of sloppy and amateurish use of probability theory....[H]owever, Cook was asked by the Hall of Fame in Cooperstown to donate the slide rule on which he did some of his calculations for Percentage Baseball. 'I am more than content,' he typed in a note of appreciation, 'to present my last testament herewith to the Greatest Game of them all.'" (excerpted from Alan Schwarz, The Numbers Game St. Martin's Press, 2004)

Great Pull-ups that Don't Leak!
Size: 3T-4T, Unit Count: 20
I was on the hunt for the perfect potty training pants for my little guy, and Pull-Ups Boys' Potty Training Pants in size 3T-4T turned out to be a great find. We’ve tried a few different brands, but these have been the most reliable. The design is fun and colorful, which my son loves, and it makes him excited to wear them. The fit is spot on for his size (32-40 lbs), and he moves around comfortably without any leaks. The absorbency is impressive – it gives me peace of mind knowing accidents won’t mean a complete outfit change. Overall, these Pull-Ups have made the potty training process a lot smoother for both of us. There are a few things to note, though. The price is a bit higher compared to some other brands, but I believe the quality justifies it. Also, while they are great during the day, we still need a bit more protection at night. I find myself using an extra layer for nighttime just to be safe. The packaging could also be improved – a resealable option would be nice to keep the remaining training pants fresh and organized. Despite these minor issues, I’m really happy with the product, and my son is well on his way to being fully potty trained. Pros: - Fun and colorful design that my son loves - Perfect fit for 32-40 lbs, allowing comfortable movement - Excellent absorbency, minimizing leaks - Helps make the potty training process smoother Cons: - Slightly higher price compared to other brands - Not as effective for overnight use, requiring additional protection - Packaging lacks a resealable option for convenience

Leak proof training pants
Size: 3T-4T, Unit Count: 112
These training pants are amazing. My son uses them whenever he’s taking a nap or sleeping throughout the night. I’ve ordered these multiple times and we’ve never had an issue with leaking.

Great for potty training
Size: 3T-4T, Unit Count: 20
We really like these pull ups and they have worked well for us during potty training. They are easy to pull on and off, which is great for toddlers who are learning to be more independent. They fit well and do a good job containing messes without leaking. I also like that they feel comfortable and not too bulky, so my child can move around easily. Overall, these have been a reliable option for us and something we continue to use during this stage.

Preferred by daycare teachers!
Size: 4T-5T, Unit Count: 99
Preferred by daycares because they open and close on the sides and kids can learn to pull on and take on on their own

Nice
Size: 3T-4T, Unit Count: 112
Good pull ups, it could get a little linty but it fits perfectly on my toddler. It stretches which I love. I do love how I could strap and unstrap the sides of the pull up. The designs on the pull up are cute. It holds a lot of pee and soaks it up very well. It’s comfortable on my toddler and the pee and poop doesn’t leak out of it. It is worth the money.
