2024 Fantasy Outlook
Jansen recorded his 400th career save last May en route to his 4th All-Star nomination. The veteran closer finished with 29 saves, enough to overtake Craig Kimbrel for the top spot on the active saves leaderboard. Jansen only made 51 appearances, his lowest mark since 2015, as he dealt with various ailments (back, knee, hamstring). Only a bout with COVID required a trip to the IL, though, and Jansen was still able to close out 67.4% of Boston's total saves. While there was concern he would have trouble adjusting to the pitch clock - he was dead last in pitch tempo (18.9 sec) with the bases empty - he only had 3 pitch clock violations all year, all in one game. Jansen also added velocity, averaging 94.3 mph (+2.1% difference from 2022) on his trademark cutter that he threw 78.8% of the time. Jansen is clearly on the downswing of his career - his 1.28 WHIP last season was his worst to date - but expecting another 25+ saves from him is not unreasonable. Read Past Outlooks

Latest Fantasy Rumors
Finds trade rumors frustrating
Jansen, who is dealing with lat soreness early in spring training, indicated he's been frustrated by rumors the Red Sox are looking to trade him, reports Sean McAdam of The Springfield Republican.
ANALYSIS
Boston is looking to shed money for 2024 and is hoping to find a team willing to take on most of the $16 million Jansen is owed. The veteran closer went 29-for-33 in save chances last season and had a 3.63 ERA, 1.28 WHIP and 52:17 K:BB over 44.2 innings. The lat injury isn't believed to be a serious issue, though he'll likely need a clean bill of health in order for a trade to go through.

Jansen wore a different uniform in 2022, but finished second in the league with 41 saves for Atlanta to bring his career total to 391, which ranks eighth all-time and second among active saves leaders. The 35-year-old has been fairly consistent over the past few seasons, with both his pitch mix and output. Jansen threw his famous cutter 65% of the time as his primary strikeout pitch, while occasionally mixing in a sinker (22%) that he mostly threw against left-handed batters, and a slider (13%). The veteran's arsenal yielded a respectable 3.38 ERA (2.76 SIERA), 1.05 WHIP and 32.7% strikeout rate, the latter being his highest since 2017. He also lowered his walk rate to 8.5% and his average velocity (93.7 mph) was surprisingly among the best of his career. If Jansen can maintain this level of production in his mid-to-late 30s, he's a lock to join the top five all-time saves leaders. He'll get the opportunity to do just that after signing a two-year, $32 million deal with Boston.
