It's all about the youth. That’s where the Yankees are now, with the World Series between Houston and Los Angeles set to begin tonight at Dodger Stadium. The foundation of the club was formed in 2017, with Aaron Judge (25), Gary Sanchez (24), Greg Bird (24) and Luis Severino (23) leading the way. That quartet, plus Jordan Montgomery (24) and Chad Green (26) — all of them pre-arbitration eligible — made just under $3.3 million combined this past season. For a franchise looking to pare down its payroll below the $197 million luxury-tax threshold in 2018, getting a tax rate reset in advance of a potential free-agent spending bonanza in 2019 (the class will include Bryce Harper, Manny Machado and maybe Clayton Kershaw if he opts out), that’s significant. And more young, cost-controllable Baby Bombers will dictate how the Yankees conduct business this offseason. CC Sabathia ($25 million), Alex Rodriguez ($21 million), Matt Holliday ($13 million), Michael Pineda ($7.4 million) and Todd Frazier ($5 million adjusted) will account for $71.4 million coming off the books. Still, between Masahiro Tanaka ($22 million if he opts in), Jacoby Ellsbury ($21.1 million), Aroldis Chapman ($20 million), Chase Headley ($13 million), David Robertson ($13 million), Brett Gardner ($11.5 million) and Starlin Castro ($10.9 million), the Bombers already have $111.5 million committed to seven players for 2018. Add in projected arbitration figures calculated by for Adam Warren ($3.1 million), Didi Gregorius ($9 million), Dellin Betances ($4.4 million), Sonny Gray ($6.6 million), Austin Romine ($1.2 million), Aaron Hicks ($2.9 million), Tommy Kahnle ($1.3 million) and Chasen Shreve ($900k) totaling nearly $30 million, and you can see how the numbers add up quickly, and things can get pretty complicated.
