In a series of roster adjustments announced today before their clash with the Chicago Cubs, the Milwaukee Brewers revealed that outfielder Joey Wiemer has been placed on the 10-day injured list due to discomfort in his left knee. Andruw Monasterio, an infielder, has been summoned from the minors to fill Wiemer’s spot on the team roster.

The Brewers, who initially seemed to have an abundance of outfield talent, are now grappling with injuries. Wiemer’s addition to the injured list follows the sidelining of teammates Christian Yelich and Garrett Mitchell. Despite Wiemer’s struggles at the plate this season, with a meager four hits in 24 at-bats, his career stats of .269/.296/.492 against left-handed pitchers, paired with his defensive capabilities, had positioned him as a valuable fourth outfield option during the absences of Mitchell and Yelich.

However, Wiemer’s return timeline is uncertain. Milwaukee Journal Sentinel’s Curt Hogg reported that Wiemer underwent an MRI which showed no ligament damage in his knee but revealed a strained muscle.

According to Hogg, Wiemer is currently unsure when he’ll be able to play again. With Wiemer out, the Brewers will likely rely on Sal Frelick, Jackson Chourio, and Blake Perkins to patrol the outfield, with Jake Bauers and prospect Chris Roller as additional, albeit less experienced, options.

Elsewhere in the NL Central, St. Louis Cardinals reliever Keynan Middleton is progressing well in his recovery from a forearm strain that disrupted his Spring Training.

Following a platelet-rich plasma injection in his elbow last month, Middleton has experienced no discomfort and plans to test his arm further in upcoming mound sessions. An effective comeback for Middleton, who last season boasted a 1.88 ERA and a 30.4% strikeout rate with the Yankees, could significantly strengthen the Cardinals’ bullpen.

Cincinnati Reds outfielder TJ Friedl is also making notable strides in his recovery from a preseason right wrist fracture. Manager David Bell described Friedl’s progress as being on a “fast track” back to the majors.

Having started a rehab assignment recently, Friedl’s return will be decided based on his performance and the number of at-bats he accumulates in the minors. His reinstatement could greatly benefit the Reds, considering Friedl’s .279/.352/.467 slash line in 138 games last season, especially in light of the team’s current reliance on Stuart Fairchild and Bubba Thompson in center field.
