Zeferjahn posted a clean ninth inning with no strikeouts to earn the save Thursday against the Marlins.
Zeferjahn set down the Marlins in order on just nine pitches (seven strikes) to complete his seventh save of the season. It was the right-hander's first appearance permitting no baserunners since Sept. 12 against the Pirates. Since joining the Cubs on Aug. 3, the 28-year-old owns a 4.50 ERA, 1.50 WHIP, 19:8 K:BB and three saves in 18 innings.

Zeferjahn notched a save against the Pirates on Saturday by striking out the only batter he faced.
Chicago took a one-run lead in the bottom of the eighth inning and began the ninth with Ryan Rolison, who had already completed one frame, on the mound. Rolison gave up an infield single followed by two outs, and manager Craig Counsell then turned to Zeferjahn, who struck out Bryan Reynolds on six pitches to slam the door shut. The save was Zeferjahn's second over his past three outings dating back to Sept. 5, and no other Cubs reliever has logged a save during that stretch. Jacob Webb and Daniel Palencia have both had their share of struggles lately, so Zeferjahn could be sneaking into the closer mix late in the campaign, though it's too early to say he's the team's primary ninth-inning option.

Zeferjahn tossed 1.2 scoreless innings of relief to earn the save in Saturday's 6-5 win over the Marlins. He walked one and struck out one.
With regular closer Jacob Webb (forearm) remaining out of action, Zeferjahn recorded his fifth save of the season and first since Aug. 2, when he was still a member of the Angels before getting traded to Chicago a day later. The righty reliever hasn't been particularly sharp with the Cubs yet, as he's recorded a 5.68 ERA across 12.2 innings with his new team. Zeferjahn still misses plenty of bats, and he should be given chances to turn things around down the stretch as a key member of Chicago's bullpen.

Zeferjahn (4-4) allowed an unearned run on a hit and a walk while retiring two batters to take the loss in Friday's 6-5 extra-inning defeat to the Mariners.
Zeferjahn was tasked with working the bottom of the 10th inning in a 5-5 game, and he ended up serving up a walk-off single to Leo Rivas. It was the righty's first loss since he joined the Cubs at the trade deadline, with his last defeat coming back in May when he was with the Angels. Zeferjahn has struggled a bit with his new team, as he now has a 5.87 ERA and 1.96 WHIP across 7.2 innings in eight appearances. He does at least have a strong 12.9 K/9 in a Chicago uniform.

Zeferjahn allowed a solo home run but also retired two batters via strikeout to earn a hold in Wednesday's 7-6 win over the Dodgers.
Zeferjahn allowed a solo home run to Shohei Ohtani, which happens to even the best pitchers. The hard-throwing righty rebounded from that small blemish to tally two more strikeouts, bringing his season-long total to 77 across 53.1 innings. Zeferjahn has now recorded a hold in each of his first two appearances since joining the Cubs at the trade deadline, working ahead of Jacob Webb on both occasions. That seems to indicate that Webb has the inside track on the closer role, at least until Daniel Palencia (elbow) returns, but Zeferjahn has the stuff to be effective in the ninth inning if the Cubs decide to go in that direction at some point.

The Cubs acquired Zeferjahn from the Angels on Monday in exchange for Moises Ballesteros and Mason McGwire, Jeff Fletcher of The Orange County Register reports.
Zeferjahn helps to bolster a Cubs bullpen that desperately needed help. He could serve as the team's closer as things stand right now, though the Cubs could make further additions and they'll also aim to get Daniel Palencia (elbow) back eventually. Zeferjahn holds a 3.66 ERA and 75:32 K:BB over 51.2 innings for the Angels this season, logging four saves along the way. He's under team control through 2030.
