The Marlins optioned Kempner to Triple-A Jacksonville on Wednesday, Christina De Nicola of MLB.com reports.

Kempner was summoned Tuesday from the minors and made his major-league debut in Miami's 9-7 loss to Baltimore with a perfect inning out of the bullpen. He'll make room on the roster for a fresh bullpen arm in Dax Fulton, who was called up from Jacksonville in a corresponding move.

Henderson is slated to start Sunday's game against the Yankees at American Family Field, Adam McCalvy of MLB.com reports.

The 24-year-old righty will unsurprisingly stick around in the rotation for another turn after a stellar showing in Washington this past weekend, when he struck out eight Nationals and allowed two earned runs on three hits and no walks over six innings. With Quinn Priester (shoulder/wrist) recently getting pulled off his rehab assignment following a setback and with Brandon Woodruff (shoulder) facing an uncertain timeline for a return, Henderson should be in line for an extended look in the big-league rotation. Through his first seven starts in the majors dating back to last season, Henderson has performed at an elite level with a 2.43 ERA, 0.96 WHIP and 44:9 K:BB in 33.1 innings.

Misiorowski (hamstring) will start Friday's series opener versus the Yankees at American Family Field, Adam McCalvy of MLB.com reports.

Despite making an early exit in his most recent outing last Friday against the Nationals due to a hamstring cramp, Misiorowski was able to go through his typical between-starts regimen and appeared on track to take the hill on four days' rest in Wednesday's series finale in St. Louis. However, a rainout Tuesday resulted in all of Milwaukee's starters being pushed back a day, and with the Brewers off Thursday, Misiorowski is now lined up to start the series opener versus the Yankees. The 24-year-old righty will carry a 2-2 record, 2.84 ERA and 1.00 WHIP into Friday's start.

Williams (5-2) took the loss Tuesday against the Royals, allowing five runs on eight hits and two walks with seven strikeouts across six innings.

After he was tagged for six runs over six innings against the Blue Jays on April 24, Williams pitched a season-high 7.2 innings of one-run ball against Tampa Bay last week. Williams' ERA has ballooned from 2.12 to 3.28 with the two bad outings sandwiched around his dominant start against the Rays. Williams served up a pair of homers to lefties Isaac Collins and Michael Massey at the bottom of the Royals' lineup Tuesday. Through 49.1 innings, Williams has an MLB-best 60 strikeouts, though walks (21 issued) remain a problem for the right-hander. He's in line to face the Twins at home Sunday.

Alcantara didn't factor into the decision in Tuesday's 9-7 loss to the Orioles, surrendering seven runs on eight hits and three walks over 4.1 innings. He struck out five.

While Alcantara didn't serve up any homers, four of the eight hits off the right-hander went for extra bases -- two each by Pete Alonso and Samuel Basallo -- as he got tagged for seven runs in a start for the second time in 2026. Tuesday's outing was his shortest of the season, and he'll take a 4.01 ERA, 1.28 WHIP and 36:18 K:BB through 51.2 innings into his next start, which lines up to come at home this weekend against the Nationals.

Urena (knee) is listed as the Angels' probable starting pitcher for Wednesday's game against the White Sox in Anaheim.

During his most recent start in Friday's 4-3 loss to the Mets, Urena was lifted from the contest after taking a Bo Bichette comebacker off his right knee in the top of the sixth inning. His early exit looks to have just been precautionary, with manager Kurt Suzuki telling Rhett Bollinger of MLB.com afterward that Urena was diagnosed with a bruise and no other damage. The 22-year-old right-hander was apparently able to complete his between-starts bullpen session without a hitch and should face no limitations Wednesday.

Bassitt didn't factor into the decision in Tuesday's 9-7 win over the Marlins, giving up four runs on six hits and three walks over four innings. He struck out three.

Miami tagged the veteran righty for runs in each of the first three frames before Bassitt finally delivered a clean fourth, but he still got the hook after 76 pitches (42 strikes) with Baltimore holding a 7-4 lead. Bassitt has been able to keep the ball in the yard this season, serving up just three homers in 32 innings, but that's about the only positive takeaway from his performance so far. He'll carry a 5.91 ERA, 1.91 WHIP and 20:17 K:BB into his next outing, which is set to come at home this weekend against the A's.

Perez will start Wednesday's game against the Mariners in Seattle.

Grant Holmes had initially been listed as Atlanta's starter for Wednesday, but the team will instead pivot to Perez after the veteran southpaw wasn't needed in relief in the first two games of the series. According to Mark Bowman of MLB.com, the change doesn't necessarily mean that Perez will be a regular in the rotation moving forward, or that Holmes will be headed to the bullpen on anything more than a short-term basis. Whether he's been used as a starter or reliever, Perez has been excellent this season; he'll take a 2.22 ERA and 0.99 WHIP over 28.1 innings into Wednesday's outing.

Sanchez (3-2) picked up the win Tuesday in a 9-1 rout of the A's, allowing three hits and a walk over eight scoreless innings. He struck out 10.

The southpaw tied his season high in Ks in his best performance of the season, as Sanchez racked up 22 swinging strikes among his 97 pitches (69 total strikes) en route to his fifth quality start of the year. Sanchez has given up more than two runs only once in eight trips to the mound, and he'll take a 2.42 ERA, 1.34 WHIP and 60:14 K:BB through 48.1 innings into his next start, which is scheduled to come at home this weekend against the Rockies.

Severino (2-3) took the loss Tuesday as the A's were routed 9-1 by the Phillies, allowing one run on seven hits and two walks over five innings. He struck out three.

The veteran right-hander's only real mistake came in the third inning, when Bryce Harper got hold of a hanging sweeper and launched it over the right-field wall, but Severino had no margin for error with Cristopher Sanchez delivering eight scoreless innings for the Phillies. Severino is turning things around after a bumpy beginning to the season, giving up exactly one run in three straight starts, and he'll take a 4.15 ERA, 1.48 WHIP and 43:25 K:BB through 43.1 innings into his next outing, which lines up to come on the road this weekend in Baltimore.
