The Chicago White Sox have an opening in their starting rotation after they designated right-hander Brad Keller for assignment, but manager Pedro Grifol didn't sound like he was jumping at the chance to give right-hander Michael Soroka another shot in the rotation. "Soroka had a good [relief] appearance, but I don't know if he's going to be the guy we want to do that. "We'll make that move when we have to, which would be Wednesday-Thursday," Grifol said. The 26-year-old Soroka was recently demoted to the bullpen, but he looked much better in a long-relief role on Saturday, tossing four scoreless innings while striking out seven. However, he did walk four and has surrendered 33 runs (31 earned) on 42 hits (10 home runs) while walking 24 and striking out 24 in 43 2/3 innings in his nine starts. We don't blame the White Sox for being hesitant to go back to Soroka as a starter.

The Washington Nationals have officially sent right-handed pitching prospect Cade Cavalli (elbow) on a minor-league rehab assignment with the Florida Complex League Nationals, according to the team's transaction log. Cavalli is trying to return after having Tommy John surgery, and his first rehab start in the Rookie League will be his first game action since the 2022 season. Given the nature of the 25-year-old's rehab and his long layoff, he's likely to spend all 30 days on his rehab assignment before the Nationals decide what to do with him. The team's No. 5 prospect, per MLB Pipeline, allowed seven earned runs in 4 1/3 innings in his first big-league start in 2022 but hasn't been back to the big leagues since because of his elbow injury. Cavalli should return to the majors at some point in 2024, but fantasy managers in redraft leagues may want to temper expectations.

Washington Nationals outfielder Lane Thomas (knee) will begin a minor-league rehab assignment with Double-A Harrisburg on Tuesday, and if all goes well, he'll play again on Wednesday. The team will then decide if Thomas is ready to come off the injured list or if he needs more time on his rehab assignment. If the Nationals are happy with what they see from the 28-year-old on Tuesday and Wednesday, he could return to the big-league lineup on Friday for the series opener against the Seattle Mariners. Thomas has been out almost a month with a Grade 2 MCL sprain in his left knee, but he should be rostered in all fantasy formats despite going 16-for-87 (.184) before his injury. He already has 11 stolen bases in 22 games in 2024 after being a 20-20 man in 2023.

Milwaukee Brewers right-hander Joe Ross (back) left his start after just 15 pitches in the first inning on Monday against the Miami Marlins with back tightness. Manager Pat Murphy said in the dugout that Ross was dealing with some back tightness before the game but felt good enough to continue after warming up. However, Ross' back tightness returned in the first inning. In his lone inning of work, Ross gave up a hit and allowed a walk to the Marlins in the bottom of the first inning. It's unclear exactly how serious the 30-year-old's back injury is, and we probably won't know more until Tuesday. But if you have been using Ross in deeper fantasy leagues, you may want to start preparing right now just in case he has to go on the injured list. Entering Monday's game, Ross was 2-4 with a 4.61 ERA and 1.37 WHIP with 35 K's in 41 innings over his eight starts.

Tampa Bay Rays right-hander Zach Eflin (back) said his back issue popped up near the end of his last start and feels similar to last year, when he missed around two weeks with a similar back injury. Manager Kevin Cash said it was an unfortunate injury but also considers it similar to last year, although the skipper did say he thought it could be two to four weeks this year. The Rays put the 30-year-old on the 15-day injured list on Monday with a lower-back injury. Eflin had back issues toward the end of last year as well, so it's definitely something to be concerned about for fantasy managers that have him rostered. The former 33rd overall pick by the San Diego Padres in 2012 won 16 games in his first year in Tampa in 2023 and had a career-best 3.50 ERA. Eflin deserves to be stashed in fantasy formats after starting 2024 with a 3-4 record, 4.12 ERA, 1.17 WHIP, four walks and 44 K's in 59 innings.
