The 2020 World Series is a clash of extremes. The Los Angeles Dodgers are Goliath, armed with high-priced stars such as Mookie Betts, Cody Bellinger, Clayton Kershaw, and the second-highest payroll in baseball. The Tampa Bay Rays are David, outfitted with a relatively unknown cast of players, the third-lowest payroll, and a philosophy that’s hard-wired to baseball’s age of analytics. The Rays, who opened the World Series Tuesday night at Globe Life Field in Arlington, Texas, just might have created a blueprint that other teams can follow, including a mid-market team like the Rockies.
