Baines was appointed to the newly created position of assistant hitting coach where he will work alongside regular hitting coach Jeff Manto. Boston was promoted to the first-base coaching box after spending the past 12 seasons as the club's minor league outfield coordinator.
"I think it kind of evolved a little last year with what Harold was doing," manager Robin Ventura said of Baines' new role. "It's one of those things where it's more of his passion. I feel lucky to have him and what he has been able to be with the coaching staff. The way the game is going, a lot of different teams are doing it."
To round out the staff, Thigpen will become the bullpen coach, replacing Juan Nieves, who left to become the pitching coach of the Boston Red Sox. The club's former closer has spent the past four seasons as a minor league pitching coach for the White Sox and was also a manager at Bristol, a rookie-league affiliate, for two seasons.
Thigpen has no issues with being the new right-hand man of pitching coach Don Cooper.
"I'll just look to be some reinforcement for him," Thigpen said. "He is the pitching coach, and I'm the bullpen coach. There are some guys there who I have had (in the minor leagues) the past couple of years. The bottom line is, I don't foresee any problems. We will get together and continue the success the pitching staff has had in Chicago."
The rest of the coaching staff under Ventura remains the same. Along with Cooper and Manto, Joe McEwing remains the third-base coach, with Mark Parent as bench coach and Mark Salas as bullpen catcher.
