2023 Fantasy Outlook
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. Read Past Outlooks

Returns to mound Monday
Jansen (illness) made a scoreless appearance Monday versus Atlanta during Grapefruit League play during his return to action.
ANALYSIS
Jansen loaded the bases on a hit and a couple walks but was able to escape unscathed by inducing an inning-ending double-play ball. The closer had exited his previous appearance due to lightheadedness, but he's fine now and will be ready to roll on Opening Day.

Jansen is clearly no longer the lockdown force who averaged 100 strikeouts a year from 2011-2017, but he can still get the job done in the ninth innings, saving 38 in 43 tries last season. Jansen began throwing fewer cutters and more sinkers in 2020, then continued it last year. He was able to induce more groundballs, but he also recorded a 12.9% walk rate, the highest mark since his rookie season. His 30.9% strikeout rate was down from his salad days, but more than sufficient to remain one of the more dominating closers. Jansen's 288 saves since 2014 are by far the most in the league so it's likely he will displace Will Smith as Atlanta's closer after inking a one-year, $16 million contract in March.
