Milwaukee Brewers manager Pat Murphy said in his pregame session on Monday that rookie left-hander Robert Gasser (elbow) is dealing with "some tightness, soreness" in his left elbow and that he's in the process of receiving a second opinion. In just the fifth start of his rookie season on Saturday against the Chicago White Sox, Gasser gave up three runs in five innings and was handed a no-decision. The 25-year-old southpaw apparently complained of elbow soreness and tightness after that outing, though, and now is unlikely to make his next scheduled turn in Milwaukee's rotation this week against the Philadelphia Phillies. The Brewers are likely to play it safe with their No. 4 prospect, per MLB Pipeline, so don't be surprised if he eventually lands on the injured list. Gasser has gone 2-0 with a 2.57 ERA and 1.04 WHIP with a 16:1 K:BB in his first five MLB starts in 2024.

Toronto Blue Jays rookie right-hander Yariel Rodriguez (back) is scheduled to make his next minor-league rehab appearance for Triple-A Buffalo out of the bullpen as a reliever on Wednesday. The Blue Jays want to keep Rodriguez stretched out and wanted him to come out of the bullpen at least once on his rehab assignment. During his outing on Wednesday, he's slated for around 55 pitches or three to four up-and-downs. The 27-year-old Cuban hurler has already made three rehab starts, so if all goes well on Wednesday, he could come off the 15-day injured list and return to the major-league roster soon. With Alek Manoah (elbow) out for the foreseeable future, Rodriguez and Bowden Francis (forearm) are Toronto's best options to fill the vacant rotation spot. Given Rodriguez's limited workload over recent seasons, Toronto will continue to limit his innings the rest of the way.

Toronto Blue Jays veteran first baseman Joey Votto (ankle) is still taking live at-bats and working through a running progression, and there is no timetable for him to get into game action. A severe right-ankle sprain that Votto suffered in spring training when he stepped on a bat in the dugout has kept him on the injured list so far in 2024. The 40-year-old long-time Cincinnati Reds All-Star first baseman continues to do baseball activities, but there appears to be no rush to get him playing in games again. The Canadian product hasn't been an All-Star since 2018 and hasn't played in over 100 games since 2021. In his 65 games in 2023 in his final season with the Reds, Votto hit just .202 (42-for-208) but managed to hit 14 homers while driving in 38. When healthy, Votto probably won't be anything more than a left-handed bench bat for the Blue Jays.

Arizona Diamondbacks right-hander Zac Gallen (hamstring) will begin his throwing progression on Tuesday, according to manager Torey Lovullo. A right-hamstring strain sent Gallen to the injured list, but he could be back when eligible since the injury wasn't related to his pitching arm. The 28-year-old only made it through six pitches in his last start on Thursday against the New York Mets before being pulled from the game and placed on the injured list on Friday. If Gallen doesn't have any setbacks with his hamstring, it's likely that he'll only need a couple of bullpen sessions before rejoining Arizona's starting rotation. He's a must-start every time he takes the mound in fantasy lineups, but he could be on a pitch count his next time out. After making his first All-Star team in 2023, Gallen has so far gone 5-4 this year with a solid 3.12 ERA (3.25 FIP) and 1.14 WHIP with 60 strikeouts and 15 walks in 57 2/3 frames over his 11 starts.

Arizona Diamondbacks shortstop Geraldo Perdomo (knee) will start his minor-league rehab assignment with Triple-A Reno on Wednesday. This was the original plan after Perdomo started taking at-bats in the Arizona Complex League over the weekend. Perdomo will now face stiffer competition at Reno and could be cleared to return from the 10-day injured list later this week if he doesn't suffer any setbacks with his knee. The Snakes have used a combination of rookie Blaze Alexander and more recently veteran Kevin Newman at shortstop since losing Perdomo to a knee injury early in April. The 24-year-old Perdomo will return to starting duties at the 6 in the desert when he's fully healthy after being named to his first career All-Star team in 2023 with a .246/.353/.359 slash line, six homers, 47 RBI and 16 steals in 144 games.
