All the pieces of the puzzle that’ll make John Farrell the next manager of the Red Sox are now in place.

Alex Speier of WEEI.com reports that Boston will receive right-handed reliever David Carpenter along with their new skipper in exchange for middle infielder Mike Aviles. Farrell has already signed a three-year contract with the Sox and will report to Fenway Park this week to be formally introduced.

Carpenter registered an ugly 8.07 ERA and 2.07 WHIP across 32 1/3 innings this season between the Astros and Blue Jays. The 27-year-old former 12th-round pick had a 3.08 ERA, 1.10 WHIP and 25/7 K/BB ratio in 26 1/3 innings at Triple-A.

Aviles, 31, hit .250/.282/.381 with 13 home runs, 14 stolen bases and 60 RBI over 136 games in 2012.

It’s a deal with a fairly clear winner in Toronto, but the Red Sox are willing to chance it that Farrell can become something special. The former Boston pitching coach had a 154-170 record in his two years with the Jays.
