2019 Fantasy Outlook
Jansen entered 2018 as the undisputed top closer, but immediately tested that distinction. With his cutter down a few ticks coming out of the spring, Jansen blew two saves in his first seven outings. He regained some heat thereafter and converted 37 of his next 39 chances, but didn’t quite resemble the relief ace of old. Most notably, Jansen's strikeout and walk rates moved steeply in the wrong directions, with his 22.5 K-BB% amounting to a 13-point decline from any of the previous three years. That contributed to Jansen finishing with an ERA above 3.00 for the first time ever, a mark that likely would have been worse if not for a .234 BABIP (career .268). The heart issue that cost Jansen time in 2011 and 2012 also popped up last August, though he’s hopeful an offseason procedure remedied the matter. Still, Jansen’s place among the top-tier closers no longer seems certain, despite the 2018 model being a fringe top-five option. Read Past Outlooks

Jansen (chest) is expected to start working out Monday at Dodger Stadium following heart surgery earlier this week, Fabian Ardaya of The Athletic reports.
ANALYSIS
Everything seems to be going as planned for Jansen following his procedure to fix an irregular heartbeat, so there shouldn't be any concern over his status heading into this upcoming spring. Aside from facing live hitters, he's been cleared to resume all baseball activities. In addition, Jansen spoke to MLB Network on Wednesday morning and emphasized that he won't have any problems pitching in the high-altitude conditions of Colorado in the future while mentioning that he will receive fluids each day the team is in Denver to make sure he's hydrated. All in all, Jansen said he's feeling great and is excited to get his heart rate up by getting back on the field next week. He should be considered one of the top ninth-inning options in 2019 and beyond.

Jansen is one of the best closers of this generation, if not the best. The 2017 season didn't end as he'd hoped -- Jansen allowed runs in three consecutive appearances and blew a save in the World Series -- but the right-hander was absolutely dominant throughout most of the year. He posted a 1.31 FIP (best among all pitchers with at least 50 innings) and 39.5 K-BB percentage while going 41-for-42 in save chances during the regular season. The walk rate was the lowest of his career and his swinging-strike rate was his highest mark ever, so while it seems impossible for him to get any better, the skills are elite and there aren't even any yellow flags entering his age-30 season. The team context solidifies Jansen as the top closer option on the board.
In his walk year, Jansen posted career bests in saves (47), ERA (1.83) and WHIP (0.67). Batters were simply unable to properly square up the 29-year-old's cutter, which was regularly hitting the mid-90s by season's end. That isn't a new development, as Jansen's career low strikeout rate in the majors is 37.6 percent from his rookie year in 2010. His K-BB% (37.1 percent) and FIP (1.44) both ranked second among qualified relievers last season, solidifying his place in the very highest tier of MLB bullpen arms. The new development is he showed an ability to last multiple innings in a game during the playoffs, a la Andrew Miller, throwing 20.1 innings across seven postseason games. Jansen remained where he was comfortable, signing a five-year $80 million deal with the Dodgers this offseason, making his outlook pretty straight forward. He will remain one of the top closers on the board as long as his skills remain constant.
A foot injury resulted in Jansen's 2015 debut being delayed until mid-May, but once he returned, the right-hander once again provided a stabilizing influence in what was a less-than-stable Dodgers bullpen. Jansen converted 36-of-38 save opportunities, a total that projects to 48 saves had he played the full six months. His 13.8 K/9 represented his fourth consecutive 13.0-plus mark in that category, while his 1.4 BB/9 was less than half his 2.9 career mark. The Dodgers may add new pieces to the bridge in front of him before Opening Day, but there is little to suggest that the organization sees him as anything other than a lock to be their closer in 2016. At age 28, he's firmly in his prime and should be drafted as one of the first closers off the board.
Jansen allowed 45 percent of his season’s runs in three outings. The trio of three-run outings was contained in just two innings of work and that was essentially the difference in his ERA from 2013 to 2014. Otherwise, he was still absolutely amazing with a career-high 44 saves, a 37.7% strikeout rate, and 5.3 K/BB ratio. Absent those three crazy outings and his out-of-whack .350 BABIP, he might have bested his 1.99 ERA from 2013. While his strikeout rate is technically dropping if you push out a decimal, from 39.3% to 37.7%, his swinging-strike rate is actually on the rise from 14.2% to 16.6%, meaning the strikeout rate could jump back up toward his obscene 44.0% mark from 2011. His stikeout and save totals will almost certainly fall this season, with Jansen expected to miss 8-to-12 weeks after undergoing surgery on his left foot in mid-February, but he should have no trouble regaining the closer role once healthy.
Well who knew Jansen would be a better closer than Brandon League last year? Okay, put your collective hands down. Jansen was spectacular, posting a 1.88 ERA, 0.86 WHIP, and an eye-popping 111:18 K:BB in 76.2 innings. Jansen has cut his BB/9 rate from 4.4 to 3.1 to 2.1 over the last three years while maintaining a 13.0 K/9 rate. He should be a top-five closer again in 2014 and should not have a problem topping the 2013 save total (28) with a full season handling the Dodgers' ninth-inning role.
Jansen's strikeout rate wasn't quite on 2011's historic level, but a 13.7 K/9 is still quite impressive. Jansen recorded 25 saves, 99 strikeouts, and checked in with a 2.35 ERA and impressive 0.85 WHIP. He had offseason surgery to correct a heart ailment and should be able to get through a full season in 2013 without a recurrence. Over the offseason, the Dodgers gave Brandon League a $22.5 million contract to be their closer, which sinks Jansen's fantasy value assuming that League pitches well enough to keep the job. Monitor this situation between now and Opening Day and slot Jansen accordingly.
Despite a minor heart ailment, Jansen had a breakout 2011, setting a single-season big league record with a 16.10 K/9IP (96 strikeouts in 53.2 innings) for pitchers with a minimum of 50 innings pitched. The converted catcher functioned primarily as a setup man for Javy Guerra last year, but it's likely he'll have the opportunity to compete for the closer slot come spring training. Jansen has the talent to be a top-five closer given the opportunity.
It was an eye-popping debut for the converted catcher in 2010, as Jansen rode a grand total of 56 professional innings to a key role in the Dodger bullpen. Routinely hitting the mid-90s and above, Jansen struck out 41 batters in 27 innings while posting a 0.67 ERA. Sure, the 15 walks were a few more than you'd like to see, but Jansen is still raw and improved command could easily come in time. He's set to pitch near the back end of the LA bullpen in 2011 and could find himself in the closer discussion depending on how things shake out with Jonathan Broxton's command and Hong-Chih Kuo's health.
