Doug Bochtler, the former Padres reliever who helped Trevor Hoffman with his change-up, will return to San Diego as Andy Green’s bullpen coach, according to sources.

Bochtler is familiar with Green, who became Padres manager on Oct. 29 after five seasons in Arizona’s organization. While they never worked on the same staff, Bochtler also spent the last five seasons with the Diamondbacks, all as a minor league pitching coach. This year, Bochtler served as the pitching coach for low Single-A Kane County.

Bochtler, 45, replaces another former Padres pitcher, Willie Blair, the bullpen coach each of the last three seasons. Blair’s contract expired at the end of October.
