Janson Junk is an unfortunate name for a pitcher, but he did indeed make a single start for the Brewers when Milwaukee initially placed Brandon Woodruff on the injured list back in April. The start was not a particularly memorable one as Junk went 4.2 innings and gave up four earned runs while walking four batters and striking out five.
After that, Milwaukee decided to try out some different arms in the rotation while Woodruff was out and Junk spent the rest of the season with Triple-A Nashville where he posted a 4.46 ERA in 125 innings of work.
Bennett Sousa was pretty much the classic "team needs a fresh bullpen arm and he was available" guy. He made just two relief appearances for Milwaukee in 2023 and was pretty bad in giving up four earned runs in just 2.2 innings of work.
Sadly for Sousa, a shoulder injury in the minors in June put him on the injured list and he struggled to get healthy all year long. Eventually, the Brewers would place him on waivers where the Tigers would claim him and end his time with the organization.
Alex Claudio's one and only appearance with the Brewers was very much a "blink and you'd miss it" sort of thing. The veteran lefty reliever got his opportunity in late April and recorded just a single out while giving up a pair of hits in his one game with Milwaukee.
That was pretty much the end of it as the Brewers optioned Claudio back to Triple-A immediately after that appearance and he spent the rest of the 2023 season in Nashville. He posted a 4.15 ERA in 47 appearances with Nashville and was DFAed off the Brewers' 40 man roster at the end of May.
