St. Louis Cardinals right-hander Keynan Middleton (forearm) threw off a mound again on Friday at Busch Stadium and will start a minor-league rehab assignment next week, according to manager Oliver Marmol. Middleton will report to either Double-A Springfield or Triple-A Memphis. The 30-year-old reliever is getting close to being able to make his 2024 debut with the Cardinals, and he should return to a key late-inning, high-leverage setup role in front of closer Ryan Helsley. Middleton is eligible to come off the 15-day injured list on May 17, a week from Friday. At the very least, Middleton could be worth a waiver-wire pickup in deep holds leagues after he posted a 3.38 ERA, a 1.24 WHIP, two saves and a career-high 64 strikeouts in 50 2/3 relief innings in 2023 with the Chicago White Sox and New York Yankees.

St. Louis Cardinals left-hander Steven Matz (back) played catch off the mound at Busch Stadium on Friday, according to manager Oliver Marmol. Matz will throw at a much higher intensity on Monday. Matz is dealing with a protruding disc in his lower back and was placed on the 15-day injured list a week ago with a lower-back strain. Given the severity of the 32-year-old veteran southpaw's injury, fantasy managers in deeper leagues shouldn't be expecting Matz to return when he's eligible to come off the IL. In addition to Matz's pretty serious injury, he wasn't good in his six starts before getting hurt, going 1-2 with a 6.18 ERA and 1.73 WHIP with only 17 strikeouts in 27 2/3 innings. Matz probably isn't worth holding onto in shallow-mixed fantasy leagues at this point.

St. Louis Cardinals outfielder Brendan Donovan and second baseman Nolan Gorman are both out of the lineup on Friday with the team facing Milwaukee Brewers rookie left-hander Robert Gasser, who is making his major-league debut. Rookie Michael Siani is starting in center field and is batting ninth, while Jose Fermin is at second base and hitting leadoff for the Cardinals on Friday night. Donovan has struggled so far this year, hitting .217 (31-for-143) with four homers and 19 RBI. Gorman has been even worse, slashing .172/.256/.319 with four home runs and 12 RBI in 116 at-bats. Fermin will be a deep DFS sleeper on Friday night out of the leadoff spot. The 25-year-old Dominican has three hits in only 11 at-bats in eight games this year after making his MLB debut in 2023.

The Milwaukee Brewers acquired right-hander Mitch White from the San Francisco Giants on Friday in exchange for cash considerations and designated right-hander Corbin Martin for assignment in a corresponding move. White started the year with the Toronto Blue Jays and is now on his third organization in the first month and a half of the year. The 29-year-old will likely be a swingman for Milwaukee after recording a rough 7.63 ERA (5.71 FIP) and 1.76 WHIP with nine walks and seven strikeouts in 15 1/3 innings with the Blue Jays and Giants this year, all of which have come out of the bullpen. If the former second-round pick by the Los Angeles Dodgers in 2016 out of Santa Clara makes any starts for the Brewers because of their banged-up rotation, White will merely be a shaky deep-league streaming option in fantasy.

The Milwaukee Brewers placed right-hander Joel Payamps on the bereavement list on Friday. In other moves, the Brewers selected left-hander Robert Gasser's contract from Triple-A Nashville, recalled right-hander Janson Junk from Nashville, optioned right-hander Tobias Myers to Nashville and moved right-hander J.B. Bukauskas (triceps) to the 60-day injured list. Payamps could be away from the team for as long as a week, but it's more likely that he's away for around two to three days. With Abner Uribe in the minors and Payamps away from the team, Trevor Megill is the clear favorite for saves in Milwaukee. That should be the case until regular closer Devin Williams (back) is ready to return around the All-Star break. Payamps currently has a 5.25 ERA, a 1.25 WHIP, a career-high four saves, three walks and nine strikeouts in 12 relief innings for the Brewers this year.
