Brown is listed as the Cubs' probable starting pitcher for Saturday's game against the Orioles at Wrigley Field.

Brown will make his second straight turn through the Chicago rotation after he delivered an impressive start his last time out Sunday, when he earned a win while limiting the White Sox to one earned run on three hits and no walks over five innings. Though most of his underlying ratios suggest that he's pitched far better than the 6.22 ERA he's posted over 88.1 innings in the majors this season, Brown could find himself back in the bullpen or at Triple-A Iowa following Saturday's start, regardless of how he performs. The Cubs acquired Michael Soroka from the Nationals on Wednesday, and he's expected to replace Brown at the back end of the rotation.

Nelson (6-3) took the loss Wednesday, giving up four runs (one earned) on six hits over 5.1 innings as the Diamondbacks fell 7-2 to the Tigers. He struck out eight without walking a batter.

The right-hander was rolling until the fifth inning, when a Geraldo Perdomo throwing error set the stage for a three-run frame by Detroit and handed Nelson his first loss since June 7. He still set a new season high in strikeouts, and he's been tagged for more than two earned runs only once in his last nine trips to the mound, a stretch in which he's posted a 1.95 ERA, 0.95 WHIP and 43:13 K:BB over 50.2 innings while going 4-1. With Arizona in sell mode, his run support could become shaky the rest of the way, but Nelson will look to get back in the win column in his next start, which lines up to come at home early next week against the Padres.

Atlanta selected Carrasco's contract and will have him start Thursday against the Reds in Cincinnati.

Acquired from the Yankees earlier this week, Carrasco didn't end up reporting to Triple-A Gwinnett and will end up slotting into the opening in the Atlanta rotation that was created when Grant Holmes (elbow) landed on the injured list Sunday. Over eight appearances (six starts) in the big leagues with New York earlier this season, Carrasco posted a 5.91 ERA and 1.53 WHIP over 32 innings, but the veteran right-hander had been pitching effectively lately at Triple-A Scranton/Wilkes-Barre. Over his five outings this month, Carrasco submitted a 2.23 ERA and 0.93 WHIP while issuing just three walks over 32.1 innings.

Martinez didn't factor into the decision Wednesday against the Dodgers, allowing two runs on four hits and two walks in six innings. He struck out seven.

Martinez was able to pitch at least six frames Wednesday for the first time in his last five starts, and the seven punchouts represented his highest total since his April 29 outing in San Francisco. The 34-year-old right-hander also tossed at least five frames while yielding two runs or fewer in his fourth straight appearance. Martinez owns a 4.64 ERA, 1.21 WHIP and 93:31 K:BB over 127 innings this year, and he'll have his work cut out for him against the Cubs at Wrigley Field in his next scheduled start.

Mikolas (6-8) took the loss against Miami on Wednesday, allowing two runs on five hits with no walks and five strikeouts over six innings.

Mikolas was tagged for a two-run homer by Jesus Sanchez in the third inning, but those were the only runs he surrendered. That was enough to send him to his eighth loss, however, as the Cardinals offense couldn't provide any run support. Mikolas did manage to notch his first quality start over his past seven appearances and has yielded just two runs over his past two starts. He's lined up for a tough road matchup against the Dodgers in his next outing.

Quantrill (4-8) earned the win over St. Louis on Wednesday, allowing three hits and issuing two walks while striking out three batters over five scoreless innings.

All three of the hits Quantrill gave up were singles, and he escaped a one-out, bases-loaded jam in his final inning to emerge with the victory. The performance continued an impressive stretch for the right-hander during which he's allowed just one run over 16 innings across his past three starts. Quantrill is still at a mediocre 4.79 ERA on the campaign, but he's been pretty consistent for almost three months, giving up three or fewer earned runs in 15 of his past 16 outings.

The Dodgers acquired Serwinowski on Wednesday as part of a three-team trade with the Reds and Rays, Jeff Passan of ESPN.com reports.

The Dodgers won't send anything directly to Cincinnati in exchange for Serwinowski, though the Reds will bring in Zack Littell from the Rays as the main piece in Wednesday's three-team deal. Serwinowski, 21, has been at High-A all season, logging a 4.84 ERA and 1.44 WHIP across 19 appearances (17 starts). He boasts impressive strikeout numbers (92 Ks through 74.1 innings), but he'll need to improve his command before elevating further up the Dodgers' farm system.

The Rays traded Littell to the Reds on Wednesday in exchange for Brian Van Belle and Adam Serwinowski, Jeff Passan of ESPN.com reports.

Immediately after throwing five shutout innings against the Yankees on Wednesday, Littell will now pack his bags and head to Cincinnati. The 29-year-old owns a 3.58 ERA and 1.12 WHIP through 133.1 innings following his latest showing and will give the Reds' rotation a nice boost as the team pushes for a spot in the postseason.

The Nationals traded Soroka to the Cubs on Wednesday in exchange for outfielder Christian Franklin and infielder Ronny Cruz, Jesse Rogers of ESPN.com reports.

Soroka hasn't found much success this season as a part of the Nationals' rotation, as he sports a 4.87 ERA and 1.13 WHIP across 81.1 innings (16 starts), though his 4.11 FIP indicates he's fallen victim to a bit of bad luck. The 27-year-old righty will likely bolster the back end of the Cubs' rotation as they make their push for the postseason. Otherwise, Chicago may move him back into the bullpen to work as a long reliever.

Holmes (9-6) took the loss against the Padres on Wednesday, allowing four runs (two earned) on eight hits and two walks with three strikeouts over 3.2 innings.

Holmes was tagged for four runs across the second and third innings, including a two-run homer by Gavin Sheets following a two-out error. It marked the 32-year-old right-hander's shortest outing of the season, and he hasn't gone deep enough for a quality start since June 7. Holmes owns a 3.45 ERA, 1.32 WHIP and 91:46 K:BB across 117.1 innings and will try to get back on track in a home matchup with the Guardians early next week.
