Brandon

Eisert

The 28-year-old southpaw has struggled in his time with the White Sox this season, posting a 5.93 ERA, 1.24 WHIP and a 32/8 K/BB ratio across 27 1/3 innings in his 25 appearances. He should still help to stabilize the middle of the Pirates’ bullpen given their recent struggles. The Pirates will have to make a corresponding move on Saturday before he’s added to the active roster.

Gonzalez was bumped off the White Sox’ big league roster on Friday with the return of Munetaka Murakami after slashing .244/.323/.360 with two homers and 17 RBI in 97 plate appearances. Passan notes that the Pirates plan to play Gonzalez at shortstop while Konnor Griffin is shelved. Eisert also adds a veteran arm to a bullpen that is in desperate need of reinforcements.

Brandon Eisert will get the ball to kick off the contest before Fedde makes a bulk relief appearance. The 33-year-old veteran was roughed up for eight runs over 3 1/3 innings his previous time out against the Giants last week. He’s not a recommended fantasy option.

Eisert returns to the big leagues after spending a couple weeks in the minors after a pair of rough outings for the White Sox back in mid-April. The 28-year-old southpaw holds a serviceable 4.75 ERA across 78 2/3 innings for Chicago over the last two years.

Eisert pitched on Sunday and again on Tuesday, allowing four runs on six hits in 2 1/3 innings. The White Sox will get a fresh arm up in the pen.

Eisert, 28, was a fixture in the White Sox’ bullpen throughout the 2025 campaign, registering a 4.39 ERA, 1.44 WHIP and a 74/25 K/BB ratio across 69 2/3 innings in his 72 appearances. He’ll function in a middle relief role.

Eisert will likely be one of the first relievers back up for Chicago when they need bullpen help. The White Sox are going to need a lot of bullpen help.

Eisert got the save chance for the White Sox on Tuesday as he was called on to close out the game with a two-run lead in the bottom of the ninth. He pitched a perfect frame, striking out one batter to convert his second save of the season.

It’s fitting that the White Sox’s first save in 25 games of the year came from a pitcher who had no idea he’d be in line for one. It was actually the first time this season that Eisert entered with a lead in a non-blowout situation; his previous eight appearances had seen him enter with the White Sox behind six times and then ahead by nine and 10 runs in the other two. He has a 4.76 ERA in 11 1/3 innings. The White Sox bullpen should continue to be avoided in fantasy leagues.

Eisert got the call back to the big leagues prior to Friday’s series opener against the Red Sox with Fraser Ellard (hamstring) landing on the injured list.
