Since the hirings of president of baseball operations Andrew Friedman and general manager Farhan Zaidi in 2014, the Los Angeles Dodgers have routinely fielded one of the better bullpens in all of baseball.
The new regime, in particular, has excelled at scouring the market for undervalued arms that were cut loose by other organizations. Recent examples include former starting pitchers turned relievers Joe Blanton and Brandon Morrow, who outperformed their low-risk, high-reward contracts with the Dodgers and went on to earn raises with other teams.
This method has permitted Los Angeles to spend very little on the bullpen in free agency, and instead, reinvest their dollars elsewhere.
