Farrell was absent for the final 48 games of the regular season following his diagnosis, and bench coach Torey Lovullo temporarily replaced him as the head honcho in the dugout.  

However, the Red Sox have made it abundantly clear the 53-year-old will return as manager next season despite the team's 78-84 record and last-place finish in the AL East in 2015. 

"The commitment is made to John, he'll be our manager for 2016, he should be fine," Dombrowski said earlier this month, according to ESPN.com's Gordon Edes

With his health steadily improving, Farrell can now set his sights on helping the Red Sox piece together a resurgent 2016 campaign.
