Quantrill (8-9) took the loss Thursday, allowing two runs on two hits and two walks over five innings against the Nationals. He struck out four.

Quantrill retired the side in order during three of his five frames, with the lone blemish against his line coming in the third inning when he allowed one walk and a couple of singles, capped by a two-out base knock by James Wood that drove in two. It was just the third time in Quantrill's past 11 starts that he's completed five innings with two or fewer runs allowed. During that stretch, Quantrill has a 2-5 record with a 6.41 ERA and 1.59 WHIP and 45 strikeouts over 53.1 innings. He's next scheduled to face the Marlins in the high altitude of Coors Field.

Corbin (3-12) earned the win Thursday, allowing one run on four hits and one walk over six innings against the Rockies. He struck out eight.

Corbin tossed 95 pitches in holding the Rockies to just one run, compliments of a sixth-inning solo blast by Brenton Doyle. It marks just the second time this season Corbin has allowed one run while completing at least six innings. The outing lowered Corbin's ERA to 5.73 with a 1.54 WHIP and 107 strikeouts over 141.1 innings spanning 26 starts. He's next slated to take the hill in a home matchup with the Yankees early next week.

The Padres optioned Waldron to Triple-A El Paso on Thursday, Dennis Lin of The Athletic reports.

Waldron has given up 22 earned runs across his last 14.1 innings spanning three starts, and now the Padres will try to get him back on track in the minors. It's unclear who will take over Waldron's spot in the rotation, though Randy Vasquez is on the same pitching schedule as Waldron and would be a natural fit to return from Triple-A to fill the opening.

Miller is scheduled to start Friday's game against the Rays at Dodger Stadium.

At least while Tyler Glasnow (elbow) and Yoshinobu Yamamoto (tricep) are on the injured list, the Dodgers are opting to keep Miller in the rotation as their No. 5 starter over Justin Wrobleski, who was optioned to Triple-A over the weekend. Miller returned from Triple-A to make his first start for the Dodgers since July 9 this past Saturday, when he took a loss to the Cardinals. The command and control problems that plagued Miller when he was up with the Dodgers earlier this season reared their head again in St. Louis, as he was charged with four earned runs on eight hits and one walk while also throwing four wild pitches. Even with a relatively favorable matchup on tap against the Rays at home, Miller's recent form makes it difficult to stream him with much confidence.

Matz (back) is expected to make one more minor-league rehab start prior to being activated from the 60-day injured list, Lynn Worthy of the St. Louis Post-Dispatch reports.

On Wednesday, Matz made his third rehab start for Triple-A Memphis, striking out three batters in five innings and giving up four earned runs on nine hits and one walk while pushing his pitch count up to 85. Though Matz looks to be fully stretched out at this point, the Cardinals may want to see a sharper outing from the lefty before bringing him back from the IL. According to John Denton of MLB.com, Cardinals president of baseball operations John Mozeliak previously floated the idea of the team using a six-man rotation down the stretch, though Matz could still find himself as the odd man out for a starting role once he's activated. Lance Lynn (knee) looks to be tracking toward a return from the IL around the same time as Matz, and current fifth starter Andre Pallante (3.81 ERA and 1.20 WHIP in five starts since the All-Star break) may be pitching well enough to keep his spot in the rotation.

Flaherty (10-5) picked up the win over the Mariners on Wednesday, allowing two runs (one earned) on five hits and one walk over 5.2 innings while striking out five.

Flaherty hit Randy Arozarena with a pitch to lead off the second inning and the latter would eventually come around to score Seattle's first run on sac fly from Dominic Canzone. The right-hander then kept the Mariners off the board over the next three frames before allowing the first two men to reach in the sixth. Flaherty fell one out shy of his second quality start as a member of the Dodgers, but he did improve his streak of pitching at least five innings to 22 starts. He's gone 3-0 in four starts since being acquired by his new club, posting a 3.22 ERA over that stretch.

Feltner (shoulder) allowed five runs (three earned) over 2.2 innings in his first rehab start with Triple-A Albuquerque on Wednesday.

Feltner has missed most of August with a right shoulder strain but looks to be nearing a return. He got his pitch count up to just 49 in Wednesday's outing, so it's possible the Rockies will want him to make one more appearance before re-inserting the right-hander into their rotation.

Parker (7-7) picked up the win Wednesday, allowing one run on five hits and a walk over seven innings during a 6-1 victory over the Rockies. He struck out six.

The 24-year-old southpaw took a shutout into the seventh inning before Colorado finally got on the board, and Parker left the mound after 83 pitches (61 strikes) having delivered his ninth quality start of the year, including three in four August outings. His fourth trip to the mound this month resulted in a nine-run disaster against the Phillies, however. Parker will take a 4.26 ERA, 1.25 WHIP and 104:32 K:BB through 122.2 innings into his next start, which lines up to come at home early next week against the Yankees.

Gordon (0-5) took the loss Wednesday, coughing up five runs on eight hits and a walk over four innings as the Rockies were downed 6-1 to the Nationals. He struck out two.

The rookie right-hander fell apart in the third inning, giving up three singles before Luis Garcia launched a three-run blast to right-center field. Gordon has been tagged for at least four runs in five of his first seven MLB starts, and he seems likely to lose his rotation spot once Ryan Feltner (shoulder) is ready to return. If Gordon does get another turn, he'll carry a 7.55 ERA, 1.58 WHIP and 25:6 K:BB through 31 innings into a home start early next week against the Marlins.

Munoz allowed three runs on five hits and three walks while striking out three batters over 3.1 innings in a no-decision against the Diamondbacks on Wednesday.

Munoz struggled with his control in the outing, throwing just 40 of 73 pitches for strikes. The right-hander lasted exactly 3.1 innings for the second consecutive start and has failed to get out of the fourth frame in three of his past four appearances. Walks have been a big issue for Munoz of late -- he's issued exactly three free passes in each of those three short outings. His 4.5 BB/9 is sixth worst among MLB hurlers who have thrown at least 70 innings this season.
