Frazier's deal is worth $12 million. He is coming off a season where he led the team in home runs (40) and stolen bases (15) despite a disappointing .225/.302/.464 slash line. He also ranked second on the Sox with 98 RBIs.
Coming into the offseason, Frazier, 30, was a good bet to be traded before Opening Day -- and maybe he still will be. However, there have been few rumors involving Frazier, and there still are several right-handed power-hitting free agents who remain unsigned (Mike Napoli, Mark Trumbo, Jose Bautista). Until those guys come off the market, there might not be much interest in Frazier -- especially since he is coming off a down season in terms of batting average.
He could eventually be traded for prospects as part of the rebuilding plan. Or maybe he won't be. Essentially, he's the Sox's third baseman until he's not. (How's that for insight?)
Jennings, 29, is coming off one of his better seasons -- a career-high 64 appearances with a 4-3 record and 2.08 ERA. His contract will pay him $1.4 million.
Petricka, 28, appeared in only nine games in 2016 before undergoing season-ending hip surgery. His deal is worth $825,000.
Although the Sox are rebuilding, they might enter the 2017 season with a bullpen that looks very similar to the one from last year. Closer David Robertson, set-up man Nate Jones, Jennings, Petricka and Zach Putnam all remain on the roster.
The only two guys gone from last season are Matt Albers, who was too ineffective to be retained, and Zach Duke, who was traded to the St. Louis Cardinals in July.
Right now, the projected bullpen includes the five guys listed above, plus Tommy Kahnle. After that, the Sox still need a second left-hander to go along with Jennings. As it stands, the next-best left-handed option in the organization is 25-year-old Giovanni Soto, a waiver pickup who last pitched in the big leagues with the Cleveland Indians in 2015.
Given that Robertson, Petricka and Putnam are all coming off surgery, we might not see too many changes in the bullpen this offseason -- just because the Sox need to hold onto as much veteran depth as possible to get through 2017. One thing a rebuilding team does not want is for prospects to be forced into big-league duty prematurely because of injuries to veteran stopgaps.
