The Boston Red Sox shocked the baseball world Monday when they announced that team president of baseball operations Dave Dombrowski had been relieved of his duties.

The move came less than a year after the Red Sox won the ninth World Series title in franchise history. The reigning champions brought back almost all of their roster this season, but they've failed to meet expectations and are in danger of missing the playoffs.

With Dombrowski now out the door, let's review the most noteworthy moves - for all the right and wrong reasons - that he made after joining the Red Sox in August 2015.

Best moves

Hiring Alex Cora as manager

After signing on before the 2018 season, all Cora did as a rookie manager was lead the Red Sox to a championship and a club-record 108 wins in the regular season. He got the best out of Boston's stars during that run, including an MVP performance from Mookie Betts.

Signing J.D. Martinez in free agency

Boston managed to land Martinez on a five-year, $110-million deal after a 2017 season that saw him post a 1.066 OPS with 45 home runs in 119 games. Dombrowski inked the Scott Boras client in late February, as a slow-developing offseason saw teams start a new trend in free agency by looking for cheap, controllable players. Since then, Martinez has produced a stellar .320/.394/.604 line with 224 RBIs across 281 games with Boston.
