Chicago White Sox infielder Josh Rojas (toe) will start a minor-league rehab assignment with Triple-A Charlotte on Tuesday, according to MLB.com's Scott Merkin. Rojas will be playing in his first game since suffering a hairline fracture in his right big toe back in the middle of March during spring training. When the 30-year-old veteran is fully cleared from his toe injury and is activated from the injured list, he's expected to serve as Chicago's primary second baseman. The left-handed-hitting infielder is useful in AL-only leagues due to his multi-position eligibility, but he offers little fantasy upside with his bat. Rojas hit .225/.304/.336 with eight home runs, 31 RBI and 10 stolen bases in 142 games last year with the Seattle Mariners and holds a .685 career OPS with only 34 long balls and 189 RBI in six MLB seasons. Defense at second and third base is Rojas' primary calling card.

Chicago White Sox left-hander Tyler Gilbert will serve as the team's opener for Tuesday's contest against the Milwaukee Brewers, according to MLB.com's Scott Merkin. This will be Gilbert's third straight appearance in the opener role for the White Sox, with the 31-year-old southpaw throwing two shutout innings with a walk and three strikeouts his last two times out, both against the Athletics. Gilbert hasn't been good outside of his two opening assignments, surrendering five earned runs on five hits (one homer) while walking three and striking out eight in 5 2/3 relief innings. Right-hander Bryse Wilson is expected to be Chicago's bulk reliever on Tuesday against Milwaukee. Neither Gilbert, nor Wilson should be considered by those looking for sleeper streamers this week.

Miami Marlins left-hander Ryan Weathers (forearm) had a successful first minor-league rehab start on Sunday at Single-A Jupiter, tossing three scoreless and hitless innings with no walks and six strikeouts. Weathers looked good in his first rehab outing and will now likely be moved up to Double-A or Triple-A for his next rehab start. The 25-year-old southpaw has been on the 15-day injured list since the 2025 regular season started, but he might need only one or two more rehab outings before the Marlins look to activate him and return him to their starting rotation. Fantasy managers in mixed leagues should think about scooping Weathers up if he's available on your waiver wire. He has breakout potential if he can stay healthy after going 5-6 with a 3.63 ERA (4.11 FIP) and 1.18 WHIP with 80 strikeouts and 24 walks in 16 starts covering 86 2/3 innings pitched.

The Detroit Tigers sent right-hander Keider Montero back to Triple-A Toledo on Sunday after his spot start in a doubleheader on Saturday against the Baltimore Orioles. In his third start of the year over the weekend, Montero gave up only one earned run on four hits while walking two and striking out two in 4 1/3 innings for a no-decision. It was the 24-year-old's best start of the season against a tough opponent, but he'll now head back to the farm to serve as rotation depth for the big-league squad. Montero fanned eight hitters in five innings in his season debut on April 16 against the Milwaukee Brewers but also allowed five earned runs. He has so far been up and down in three starts in 2025 after going 6-6 with a 4.76 ERA, 1.33 WHIP and 77:31 K:BB in 98 1/3 innings in his rookie year in 2024. Montero will be a streamer for those in AL-only leagues if/when he makes another start in Detroit.

St. Louis Cardinals left-hander Steven Matz will draw the start in Wednesday's game against the division-rival Cincinnati Reds at Great American Ball Park. It will be Matz's second start of the year, and he'll be pitching on three days of rest after getting two outs out of the bullpen on Saturday against the Milwaukee Brewers. The 33-year-old veteran southpaw has pitched well for the Red Birds early on in 2025 -- he's allowed four earned runs on 15 hits (no homers) while walking only three and striking out 14 in 20 innings, but he'll still be a pretty volatile streaming option in a hitter-friendly ballpark this week. In his lone start this year on April 16 against the Houston Astros, Matz got the win by giving up just one earned run in five innings while walking none and striking out five.
