Jansen pitched one scoreless inning, allowing one hit in Sunday's 9-2 win over the Twins.

EDGE Analysis

Jansen was locked into appearing in Sunday's contest no matter what, and he worked around an error by his defense and a single for a scoreless ninth inning. The 36-year-old is firmly locked into being Boston's closer in 2024, posting a 1.69 ERA and 1.22 WHIP with 14 strikeouts over 10.2 innings in 11 appearances while going 5-for-6 on save opportunities so far.

Jansen, who hasn't pitched the last six days, will be used in Sunday's game against the Twins, Peter Abraham of The Boston Globe reports.

EDGE Analysis

The Red Sox have a day off Monday and will prevent Jansen from the absence extending any further, so the closer is expected to pitch one way or another. He's pitched just once over the last nine days.

Jansen (1-0) got the win over the Cubs on Sunday, pitching a perfect inning while striking out a batter in the process.

EDGE Analysis

Jansen entered in the ninth with the score tied 4-4 and did his job by retiring the side in order in 10 pitches. He would wind up with his first win of the campaign after the Red Sox walked it off in the bottom of the inning. Jansen has now pitched three consecutive scoreless outings after blowing a save chance April 16. For the year, he owns a 1.86 ERA, 1.24 WHIP and 14:8 K:BB in 9.2 innings to go along with five saves.

Jansen struck out the side in a perfect ninth inning Saturday to record his fifth save of the season in a 4-2 win over the Pirates.

EDGE Analysis

The veteran right-hander fired nine of 14 pitches for strikes in his most impressive performance so far this season, although he did benefit from a third-strike clock violation by Michael Taylor. It's only the third time in eight appearances that Jansen hasn't issued a walk, and while his 2.35 ERA looks good, it comes with a 1.57 WHIP and 12:8 K:BB over 7.2 innings.

Jansen gave up a run on three hits in the ninth inning Tuesday for his first blown save of the season in a 10-7 extra-innings loss to the Guardians.

EDGE Analysis

Called upon to protect a 6-5 lead, Jansen instead gave up three straight one-out hits kicked off by a Tyler Freeman double off the Green Monster. The 36-year-old right-hander has been tagged for runs in back-to-back appearances after beginning the campaign with 4.2 scoreless innings, and Jansen's 9:8 K:BB remains a little worrisome, but he's converted four of five save chances and doesn't appear to be at risk of losing his grip on the closer role.

Jansen earned the save Sunday against the Angels, allowing one run on a hit and a walk with two strikeouts across one inning.

EDGE Analysis

Jansen picked up his fourth save of the season Sunday but spoiled his perfect 0.00 ERA in the process. Entering the game with two runs of cushion, Jansen hit Logan O'Hoppe with a cutter, then allowed a single to Mickey Moniak before walking Zach Neto to load the bases. While Anthony Rendon hit a sacrifice fly to plate O'Hoppe, Jansen struck out the next two batters to close out the game. Jansen has walked eight batters in 5.2 innings, but he's been nearly unhittable, with Moniak's single the first hit allowed by Jansen in 2024.

Jansen struck out one batter in a perfect ninth inning and earned a save over the Angels on Friday.

EDGE Analysis

Jansen had walked five batters in his first three outings but finally worked a clean inning Friday, his third time pitching in the last four days. Despite some early command issues, the veteran closer has converted each of his three save chances and has yet to give up a run. His velocity is still a concern; Jansen's cutter, which averaged 94.3 mph last season, was down to just 90.7 mph Friday.

Jansen's velocity is down close to three mph on his cutter to begin the season, Julian McWilliams of The Boston Globe reports.

EDGE Analysis

Jansen didn't get in much work during spring training due to a back issue and is still building up toward his usual form. He labored through back-to-back outings Tuesday and Wednesday, needing 20-plus pitches in each, but that he was able to pitch on consecutive days is encouraging. Jansen has converted both his save chances so far with a 0.00 ERA in three innings, albeit with a 5:5 K:BB.

Jansen picked up the save Wednesday against the Athletics, He issuing two walks while striking out one over a scoreless inning.

EDGE Analysis

Jansen managed to escape with his second save in as many chances despite allowing back-to-back walks with one out in the ninth. The veteran right-hander needed 21 pitches to get through the inning, with only 10 of those going for strikes, and he's now issued three free passes over his first two appearances to begin the season. On a positive note, the save was Jansen's 422nd of his career, tying him with Bill Wagner for sixth all time.

Jansen (back) is available to pitch Monday against the Athletics, Christopher Smith of The Springfield Republican reports.

EDGE Analysis

Jansen's availability was in question leading up to Monday's contest due to back tightness, but skipper Alex Cora noted pregame that the right-hander had a good day Sunday and felt good again Monday, so he'll be ready to roll if called upon. Jansen's first appearance of the 2024 season took place Thursday against the Mariners, picking up the save after fanning two and walking one over a scoreless inning.
