With the signing of NPB super-ace Yoshinobu Yamamoto (12 yrs, $325M) the LA Dodgers have purchased the services of the two best Japanese ballplayers on the planet. One of them is arguably already the best player in MLB. Shohei Ohtani's $700M takes the total outlay to over one billion dollars. If you laid one billion dollar bills end-to-end (a bill is about six inches in length) they would stretch 500,000,000 feet or about 95,000 miles or nearly four trips around the earth.
That's a lot of scratch!
MLB annual revenue is about $10B, and the total value of all 30 franchises is about $70B.
