June 4, 2023 7:31 AM : Jansen (1-3) gave up a hit and struck out the side in a scoreless ninth inning during the first game of Saturday's doubleheader, recording his 12th save of the season, but he then gave up two runs on three hits and a walk in the second game to get tagged with the loss.
Analysis: All told, the veteran closer tossed 43 pitches (26 strikes) across both games, so Jansen will likely be unavailable for a couple days to recuperate should Boston have any late leads to protect. The right-hander has been a solid addition to the Red Sox bullpen this season, posting a 3.86 ERA and 22:12 K:BB through 18.2 innings while converting 12 of 15 save chances, but the team's lack of reliable high-leverage options to support him is beginning to take its toll -- Jansen's allowed multiple runs in three of his last eight appearances.
