10. Mike Hazen, Boston Red Sox, Arizona Diamondbacks, +9.13
Hazen ran the Red Sox in 2015 and 2016 before being hired to be general manager in Arizona.
His two drafts in Boston netted 11 future major leaguers, of whom easily the most productive was outfielder Andrew Benintendi. A first-round pick in 2015 — indeed he was Hazen’s first selectee as GM — Benintendi signed for a $3.6 million bonus but gave the Sox five seasons, batting .290 for the 2018 World Series winners.
Lesser-quality trophies, at least to date, have included Bobby Dalbec and Santiago Espinal. Both arrived in the 2016 draft, and Espinal was traded to Toronto for Steve Pearce while still a minor leaguer.
In 2017, Hazen used Boston’s first round pick to take Tanner Houck, who gave the team a strong 2021 and is in the 2022 rotation.
That 2016 draft was problematic. Hazen’s first two selections were pitcher Jay Groome and shortstop C.J. Chatham, neither of whom ever played a day in the majors.
Through four drafts with Arizona, Hazen’s picks have to date yielded nothing more quantitative than backup outfielder Jake McCarthy. His No. 1 pick in 2018, Matt McClain, proved unsignable. His three most recent top picks, outfielder Corbin Carroll, pitcher Bryce Jarvis, and shortstop Jordan Lawlor, are, respectively, the system’s No. 2, 7, and 3 prospects, although all three are at Double-A or lower.
