Offseason Outlook: Boston Red Sox

Uncertainty seems to be the running theme of the Red Sox right now. Though they have World Series championships not too far in the rear-view mirror, recent seasons have seen them cut payroll and wind up in a middle ground between a rebuilding club and a frontline contender. Chief baseball officer Chaim Bloom was recently…

Previewing The 2023-24 Free Agent Class: Righty Relievers

MLBTR’s position by position preview of the upcoming free agent class concludes with a look at the right-handed relievers. While there’s no one at the top of this group who’ll rival Josh Hader among the southpaws, there are a number of impressive middle to late inning arms who’ll hit the market. Note: only players who…

Kenley Jansen Returns From COVID List

The Boston Red Sox reinstated closer Kenley Jansen (illness) from the COVID injured list on Saturday and optioned pitcher Zack Weiss to Triple-A Worcester in a corresponding move. Jansen will return to Boston's bullpen for the first time since testing positive for COVID on Sept. 13. He'll have just over a week left to pick up some save opportunities for fantasy managers still playing for a title, but the Red Sox could ease him back into the fold, especially since he had given up five runs in his previous five appearances before going on the shelf. The 35-year-old veteran right-hander hasn't recorded a save since Aug. 20 and has a 3.63 ERA, 1.28 WHIP, 29 saves and 52 strikeouts in 44 2/3 innings this year over 51 outings out of the 'pen.

Kenley Jansen Placed On COVID List

Boston Red Sox relief pitcher Kenley Jansen (illness) has been placed on the COVID-19 list on Wednesday. The veteran reliever was pulled from Tuesday's relief appearance due to fatigue and illness symptoms. Now, Jansen has tested positive for COVID-19 and will be sidelined for the next week. His absence leaves the Red Sox shorthanded in the bullpen for the time being. The assumption is that Chris Martin and John Schreiber will be the favorites in the ninth inning with Jansen sidelined.

Kenley Jansen Leaves Early With Fatigue And Illness

Boston Red Sox closer Kenley Jansen was pulled from his outing in the ninth inning in the second game of a doubleheader against the division-rival New York Yankees on Tuesday with fatigue and illness symptoms. It was a rough outing for Jansen, as he allowed two runs (one earned) on a hit while walking one before being pulled in favor of Nick Robertson after failing to record a single out. The 35-year-old should be considered day-to-day, and it's ultimately good news that he's not dealing with a specific injury or a heart-related issue that he's had in the past. The four-time All-Star is Boston's primary closer and entered Tuesday's games with a 3.43 ERA (3.60 FIP), 1.23 WHIP, 29 saves and 52 strikeouts in 44 2/3 innings of work. If he misses any upcoming save situations, they'll likely go to either Chris Martin or Josh Winckowski.

Kenley Jansen Allows Walk-Off Homer Tuesday

Boston Red Sox closer Kenley Jansen took his sixth loss of the season in Tuesday's 8-6 extra-innings loss to the Rays. Jansen came on to pitch the bottom of the 11th inning up by one with a free runner on second. He walked the leadoff hitter before allowing a walk-off, three-run home run to Brandon Lowe. This was the veteran's third consecutive day pitching, and he allowed multiple runs in two of those three outings. Despite this rough patch, Jansen has converted 29 of 33 save opportunities this season with a 3.43 ERA and a 10.48 K/9 rate. He remains a solid fantasy option, although he will likely receive a few days off after his recent heavy workload.
