Burnes (elbow) will undergo Tommy John surgery next week, Jose M. Romero of The Arizona Republic reports.

Burnes landed on the injured list Tuesday due to inflammation in his right elbow, and after receiving multiple opinions on his injury, he'll elect to go under the knife to address the issue. His surgery will put an abrupt end to his 2025 season, and he'll finish the year with a 2.66 ERA and 1.17 WHIP alongside a 63:26 K:BB across 64.1 innings (11 starts). He's likely to miss most, if not all, of the 2026 campaign as well.

Rodriguez (shoulder) has been reinstated from the 15-day injured list and will start Friday's game against the Reds.

As expected, Rodriguez will take the mound Friday, marking his first start since May 14 after he dealt with inflammation in his throwing shoulder. Rodriguez owns a 7.05 ERA and 1.70 WHIP over 44.2 innings this season. Tommy Henry was optioned to Triple-A Reno in a corresponding move.

Senzatela will follow Ryan Rolison during Friday's game against the Mets, Thomas Harding of MLB.com reports.

The Rockies are using an opener for the first time this season and will give the ball to Rolison for an inning or two before letting Senzatela step in as a bulk reliever. The change might be what Senzatela needs to get back on track, as he's taken seven consecutive losses. He's posted an 8.82 ERA and 2.02 WHIP during that stretch.

The Dodgers optioned Knack to Triple-A Oklahoma City on Friday.

Knack had taken six consecutive turns through the Dodgers rotation, posting a 4.50 ERA and a 28:12 K:BB over 30 innings, but he'll yield his spot to Justin Wrobleski. In four appearances with Oklahoma City this season, Knack logged a 3.98 ERA and a 1.19 WHIP across 20.1 innings.

The Dodgers recalled Wrobleski from Triple-A Oklahoma City ahead of Friday's game against the Cardinals.

Wrobleski is set to start Friday's contest, which will be his second MLB start of the campaign. The 24-year-old has stumbled to a 5.09 ERA over 40.2 innings with Oklahoma City, and he's allowed eight runs in nine big-league innings this season. His struggles and lack of strikeout stuff -- he has an 8.3 K/9 at Triple-A -- make him a shaky fantasy option. Landon Knack was optioned to Oklahoma City in a corresponding move.

Cardinals manager Oliver Marmol said his concern level was "not high" after Liberatore exited Thursday's start versus the Royals due to fatigue, Daniel Guerrero of the St. Louis Post-Dispatch reports.

The velocity on the southpaw's four-seamer dropped below 90 mph in the fifth inning, prompting a visit from Marmol and the trainer and the pitcher's eventual removal. However, Liberatore did not undergo imaging after the game and there doesn't appear to be any worry that he's injured. Rather, the pitcher believes mechanical issues were the main factor in him feeling fatigued. Liberatore has struggled in back-to-back starts and it's possible he's going through a "dead arm" phase after he spent the bulk of last season in a relief role. He's tentatively lined up to face the Blue Jays at home next week, but the date of his next start is not set in stone.

Rodriguez (shoulder) will start Friday's series opener against the Reds, MLB.com reports.

Rodriguez, who is on the 15-day injured list with shoulder inflammation, joined the Diamondbacks earlier this week and will be activated Friday. The left-hander's return comes at a key moment for the team, which lost Corbin Burnes (elbow) earlier this week.

Keller (1-8) took the loss after allowing six runs on eight hits and one walk while striking out five in 6.1 innings during Thursday's 8-2 loss to the Astros.

Keller gave the Pirates some length once again, but his streak of five straight quality starts was snapped on a night when the first pitch was delayed by over three hours due to rain. The result was his second-worst start of season, behind only a seven-run disaster against the Yankees back on April 4. Keller hasn't picked up a win since his opening start of the season, a time frame spanning 12 starts, despite allowing three runs or fewer in nine of them. The right-hander's ERA is up to 4.13 on the season, and his next start is scheduled for Tuesday against the Marlins.

Knack covered just 3.1 innings Thursday, allowing four runs on four hits and five walks while striking out one during a 6-5 win against the Mets. He didn't factor in the decision.

It was a tough outing for a pitcher who looked like he was turning a corner after back-to-back quality starts. Of Knack's 86 pitches Thursday, 40 of them were balls, leading to a season-high five walks. He also surrendered a season-high three home runs, though the fact all three were solo shots limited the damage. Knack has given up nine home runs in his past five outings, partially leading to his 5.12 ERA on the season. He isn't guaranteed to stick in the rotation, but the right-hander is tentatively scheduled to make his next start on the road at San Diego.

Peterson didn't factor into the decision Thursday after allowing three runs on seven hits and two walks while striking out six in seven innings during a 6-5 loss to the Dodgers.

Peterson continues to pitch well in 2025, with the three earned runs given up Thursday tying his season high through 12 outings. He's been up to the challenge in his two starts against the Dodgers with five runs allowed across 14.2 innings. The 29-year-old has thrown at least six innings in five of his last six starts and sports a 2.58 ERA over that timeframe. Peterson is next slated to start at home against the Nationals next week.
