Boston Red Sox closer Kenley Jansen (hamstring) left his appearance early on Wednesday against the Houston Astros due to right-hamstring tightness. Jansen was removed in the ninth inning after recording one out and was replaced by Nick Pivetta, who finished off the inning and eventually earned the win. Josh Winckowski came on and worked an inning to pick up his third save of the season. For now, fantasy managers should consider Jansen day-to-day until we know more about his condition, but he's unlikely to be available for the series finale against the Astros on Thursday either way. If the 35-year-old's injury causes him to miss any time, Winckowski and Chris Martin could share save duties in Boston. Jansen has been a quality fantasy closer in his first year in Beantown in 2023, posting a 2.83 ERA, 1.21 WHIP, 29 saves and 50 K's in 41 1/3 innings.

Boston Red Sox closer Kenley Jansen closed the door on the Detroit Tigers for another save on Sunday afternoon. That marks 27 saves for Jansen this year, placing him one save away from being in the top three in the American League. Jansen gave up one hit without a walk or strikeout in the clean frame, lowering his ERA to 2.97 on the year.

Boston Red Sox closer Kenley Jansen breezed through the Kansas City Royals to secure his 26th save of the season on Thursday in a 2-0 win. Jansen struck out a pair while not allowing a baserunner. With this outing, the veteran closer lowers his ERA to 3.05 and his WHIP to 1.25 while striking out 47 in 38 IP. He is now 26/29 in save opportunities and hasn't blown one since May 13. He's been an underrated gem for fantasy bullpens as a guy with a ton of job security on a pretty solid team.

Boston Red Sox right-hander Kenley Jansen came into Wednesday's contest against the Kansas City Royals in the ninth inning with a 4-2 lead. He allowed one run and a walk but struck out one and earned the save, his 25th of the season. Jansen continues to pitch well at age 35, sporting a 3.13 ERA, 1.29 WHIP, and 28.8% strikeout rate across 37 1/3 innings. That kind of production is valuable in every league, and fantasy managers should start the long-time veteran in every format as he remains Boston's closer.

Boston Red Sox relief pitcher Kenley Jansen picked up his 22nd save in 2023 as the Red Sox topped Atlanta 5-3 Wednesday. Jansen certainly added some excitement to the game by allowing a hit to Kevin Pillar and hitting Sean Murphy with a pitch. However, the situation turned around when Boston catcher Connor Wong threw out pinch runner Forrest Wall. The right-hander would then fan Orlando Arcia to end the contest. At 35 years old, Jansen now has a 2.97 ERA in 33/1 innings thrown this season.

Boston Red Sox relief pitcher Kenley Jansen recorded one out on one hit in seven pitches for his 21st save of the year on Saturday versus the New York Mets. The All-Star fireman was summoned to put out a fire fueled by Justin Garza, who quickly permitted three runs to allow New York within striking distance. Jansen followed a Garza balk with a balk of his own upon entry before a Brett Baty single would drive in Mark Vientos to get the tying run to bat. Masataka Yoshida would ultimately make a tough catch in left field to finally put the game away. Jansen's had trouble with walks at times this season, but possesses an otherwise reliable 3.06 ERA, 1.36 WHIP, and 38:14 K:BB while collecting 21 of 24 save opportunities in 32 1/3 frames.

Boston Red Sox closer Kenley Jansen shut the door on the Oakland Athletics to secure a 4-3 win on Sunday. Jansen came in for the ninth in a one-run game and allowed just a walk while striking out one to notch his third save of July. The big righty has been solid for the Bo-Sox, pitching to a 3.23 ERA and 1.37 WHIP with 36 strikeouts in 30 IP. He also hasn't blown a save since May 13, although he has a few losses sprinkled in during that span. On a decent Red Sox team, Jansen has a good chance to eclipse thirty saves for the ninth non-shortened season in a row. It's been quite a career.

Boston Red Sox right-hander Kenley Jansen allowed one run on three hits while striking out three across 1 1/3 innings to earn the save in Saturday's 7-6 win over the Blue Jays. He entered the eighth inning to protect a one-run lead. The 35-year-old struck out Cavan Biggio to end the inning. With two outs, he surrendered an RBI single to Vladimir Guerrero Jr., while Bo Bichette was thrown out at home trying to score the game-tying run during the ninth inning to end the game. Jansen notched his 17th save of the season. He owns a 3.45 ERA, 1.43 WHIP, and a 35: 13 K: BB across 28 2/3 innings in 2023. Jansen is Boston's primary closer, and fantasy managers should continue to roll with him in all formats.

Boston Red Sox relief pitcher Kenley Jansen was called upon to protect a three-run lead during Saturday's game against the Tampa Bay Rays. The right-hander immediately allowed a leadoff double to Yandy Diaz. After that, Jansen settled down and struck out the next three batters to record his 12th save of the season. The 35-year-old continues to be one of the more reliable closers in the MLB. Fantasy managers should continue to roster him in all formats.

Boston Red Sox right-hander Kenley Jansen notched his 10th save of the 2023 campaign on Saturday when his club defeated the San Diego Padres 4-2. He walked two and struck out none but worked around it without allowing a hit over his one inning of work. Jansen's now sixth in baseball with his 10 saves and owns a 3.95 ERA, 1.68 WHIP, and 26.6% strikeout rate. However, the 35-year-old is sporting a career-high 14.1% walk rate, and his 5.12 xFIP isn't encouraging. Jansen's never finished any season with an ERA above 3.71 over his previous 13 seasons, though, and he's the clear closer in Boston, so fantasy managers should continue starting the three-time All-Star in all formats.

In Wednesday's game against the Braves, veteran relief pitcher Kenley Jansen of the Boston Red Sox delivered an excellent outing. Despite allowing a base hit, he managed to navigate the ninth inning flawlessly, not allowing any runs to score. Additionally, Jansen struck out one batter and secured the save, contributing to Boston's 5-2 victory over Atlanta. This particular save marked a significant milestone for Jansen, his 400th career save and his ninth of the 2023 season.

Boston Red Sox manager Alex Cora said that closer Kenley Jansen (back) is fully available to pitch on Thursday against the Toronto Blue Jays. Jansen will be available for the first time since dealing with back tightness in his last outing on Saturday, but he was able to throw a successful bullpen session on Wednesday and has been cleared to return to the bullpen. Fantasy managers need to get Jansen back into their lineups for Thursday's ballgame. The 35-year-old veteran right-hander is off to an excellent start in 2023 in his first year in Beantown, posting a 1.04 ERA (1.28 FIP), 1.04 WHIP, six saves, two walks and 12 strikeouts in 8 2/3 innings pitched a year after he had a league-high 41 saves for the Atlanta Braves.

Boston Red Sox manager Alex Cora said that relief pitcher Kenley Jansen (back) threw a bullpen session on Wednesday and is expected to be available to pitch on Thursday in the series finale against the Toronto Blue Jays. It's good news for Jansen and Boston's bullpen, as the 35-year-old right-handed veteran hasn't pitched since suffering from back tightness in his last outing on Saturday. With Jansen still unavailable, Josh Winckowski picked up the save on Tuesday, but Jansen should return to primary closing duties for the BoSox when he's ready to return. He did blow his last save chance on Saturday when his back wasn't feeling great, but overall Jansen has a tidy 1.04 ERA (1.29 FIP), 1.04 WHIP, six saves, only two walks and 12 strikeouts in his 8 2/3 relief innings so far this year.

Boston Red Sox relief pitcher Kenley Jansen (back) is expected to avoid a trip to the injured list. The right-hander mentioned he is dealing with some back tightness after Saturday's game against the Cleveland Guardians. Jansen said he was feeling better, but won't be available for a few days. The organization hopes he'll be able to play catch within the next day or two. It doesn't sound like a serious issue, so hopefully Jansen won't need a trip to the injured list. The Red Sox will likely go bullpen by committee until Jansen is ready to return.

Boston Red Sox closer Kenley Jansen converted his sixth save of the season in Tuesday's 8-6 win over the Orioles. Jansen entered the game up by two with one out and no one on in the bottom of the ninth. He immediately got the final two outs on a groundout and lineout to end the game. The veteran has once again been extremely consistent for fantasy managers, converting all of his save opportunities with a 0.00 ERA and a 12.91 K/9 rate. Jansen has picked up right where he left off with his new team and should continue to be a high-end fantasy option.

Boston Red Sox right-handed pitcher Kenley Jansen picked up his first save of the season on Thursday, closing out the Detroit Tigers in a 6-3 win. Jansen retired the side in order, getting a groundout and two flyouts to end this one. After a 41-save season in Atlanta last year, the big righty may see a slight reduction in save opportunities on a worse Red Sox team. Still, Jansen is likely to see the majority of the save chances Boston has and should convert at a decent rate.

Boston Red Sox closer Kenley Jansen is confident that the lightheadedness that he experienced in his Grapefruit League appearance on Friday night was not due to heart issues he's had in the past and suspects it was simply dehydration. He had been working out in the hot sun in the hours before the game. Jansen would like to pitch again before camp ends, and if he does, he should be just fine for Opening Day next Thursday. Manager Alex Cora didn't express any concerns about the veteran right-handed reliever after he was pulled following his blown save against the Atlanta Braves either, so there isn't really anything to worry about here. Jansen expects to pitch in Sunday's Grapefruit League game.

Boston Red Sox closer Kenley Jansen left his Grapefruit League outing on Friday against the Atlanta Braves after feeling light-headed on the mound, according to manager Alex Cora. However, the skipper also said that Jansen should be fine. Jansen has had issues with an irregular heartbeat in the past, but this apparently doesn't seem to be connected. He was charged with his first blown save of the spring after allowed three earned runs on two hits (one homer) while walking one and striking out none in just one-third of an inning pitched. As long as the 35-year-old veteran closer is able to return in a few days, he should be good to go to open the 2023 regular season as Boston's primary closer.

The Boston Red Sox and closer Kenley Jansen agreed to a two-year, $32 million deal on Wednesday, according to sources familiar with the deal. Jansen is no longer the closer that made three straight All-Star teams with the Los Angeles Dodgers in 2016-18, but he'll be a much-needed boost to a Red Sox bullpen that was pretty bad in 2022. The 35-year-old right-handed reliever was solid in his only season as the Atlanta Braves closer in 2022, going 5-2 with a 3.38 ERA (3.21 FIP), a league-high 41 saves (48 chances), a 1.05 WHIP and 85 strikeouts in 64 relief innings. Jansen finished a league-high 54 games and will move to Boston as their primary closing option to begin the 2023 campaign. He has 391 career saves and should add stability to the back end of Boston's 'pen.

The San Francisco Giants have shown interest in free agent relief pitcher Kenley Jansen, according to Jon Morosi of MLB Network. Manager Gabe Kapler and President of Baseball Operations Farhan Zaidi were with the Los Angeles Dodgers while Jansen was holding down the closer role for that franchise. In 2022 with the Atlanta Braves, Jansen was once again excellent with 41 saves and a 3.38 ERA and 1.05 WHIP. Despite being 34 years old, he is expected to garner a multi-year contract.
