Gallen did not factor into the decision Wednesday against the Rangers, allowing three runs on five hits and two walks over five innings. He struck out one.

It's the first time in five starts that Gallen's failed to make it through six innings -- the right-hander had won his previous two outings, giving up just three runs over 12 innings in that span. Overall, Gallen's ERA sits at 5.31 with a 1.35 WHIP and 131:52 K:BB across 25 starts (144 innings) this season. He's currently lined up to face the Guardians at home his next time out.

Irvin didn't factor into the decision in Wednesday's 8-7 win over the Royals, surrendering six runs on seven hits and four walks over four innings. He struck out three.

The Nationals staked Irvin to a 5-0 lead before he even took the mound for the bottom of the first inning, but the right-hander did his best to squander it, eventually getting the hook after 83 pitches (46 strikes). It's the third time in five starts since the All-Star break that Irvin has been tagged for at least five runs, a stretch in which he's stumbled to a 7.88 ERA, 1.79 WHIP and 11:9 K:BB over 24 innings. The rebuilding Nationals don't have any obvious candidates to replace him in the rotation, however. Irvin is scheduled to make his next trip to the mound at home early next week against the Mets.

Gomber did not factor into the decision Wednesday against the Cardinals, allowing five runs on nine hits and a walk across five innings. He struck out two.

It was another tough outing for Gomber, who's given up two home runs in each of his last three starts -- Lars Nootbaar led off the fourth inning with a long ball Wednesday before Alec Burleson added a two-run shot in the fifth. Gomber remains without a win in 11 starts this season -- he's 0-6 with a 6.75 ERA, 1.61 WHIP and 32:15 K:BB across 54.2 innings. The lefty will look to turn things around in his next outing, which is tentatively scheduled for next week at home against the Dodgers.

McGreevy did not factor into the decision in Wednesday's loss to the Rockies, giving up three runs on seven hits and no walks over six innings. He struck out two.

McGreevy blanked Colorado through his first three frames before giving up a run in each of the fourth, fifth and sixth innings. Despite the shaky finish, the 25-year-old McGreevy has now made it through six innings in each of his last three outings and has two straight quality starts. His ERA sits at 4.41 through 51 innings with a 1.22 WHIP and 28:7 K:BB. McGreevy's currently scheduled to face the Marlins on the road in his next start.

The Mets activated Blackburn (shoulder) from the 15-day injured list Wednesday, Laura Albanese of Newsday reports.

Blackburn has made five rehab starts and built up to 97 pitches in his most recent outing last Friday. His return comes at a time of need after manager Carlos Mendoza said Tuesday that Frankie Montas is moving to the bullpen permanently. It's been reported by Andy Martino of SNY.tv that Nolan McLean is expected to be tapped to start in his MLB debut Saturday against the Mariners, but Blackburn also appears ready to rejoin New York's rotation. For now, though, he's likely to be available out of the bullpen.

Liberatore has had difficulty maintaining his velocity deep into starts, most recently seeing his four-seamer drop to 90-to-91 mph in the fifth inning of Tuesday's loss to the Rockies, Katie Woo of The Athletic reports.

Liberatore set down the first nine batters he faced Tuesday. However, his velocity began to slip in the fourth -- when he served up a two-run homer to Hunter Goodman -- and declined further in the fifth before he was pulled after allowing the first two runners of that frame to reach base. Liberatore has a 5.47 ERA and 12:11 K:BB over 24.2 innings since the start of July and hasn't recorded an out beyond the fifth inning in any of those outings. The lefty could be wearing down as he goes through his first full season as a starter at the major-league level. Liberatore will make his next scheduled start Monday in Miami, but if he struggles again, the Cardinals will consider altering his role. One option is to piggyback him with Kyle Leahy.

Scott threw a bullpen session last week and is "doing well" in his recovery from right elbow surgery, Will Sammon of The Athletic reports.

It was Scott's first bullpen session since he underwent a hybrid Tommy John and internal brace procedure on his pitching elbow last September. He's not expected to pitch this season and remains on the 60-day injured list.

The Reds activated Greene (groin) from the 15-day injured list Wednesday.

In a corresponding move, the Reds optioned Sam Benschoter to Triple-A Louisville. Greene hasn't pitched since June 3 due to a strained groin but will return for the finale against the Phillies. He's also dealt with back issues this season, making a total of 11 starts and registering a 2.72 ERA, 0.97 WHIP and 73:14 K:BB across 59.2 innings. He went 5.1 innings and threw 79 pitches in his latest rehab start last Friday.

Junk came away with a no-decision Tuesday against the Guardians, giving up three runs on six hits over five innings as the Marlins lost 4-3. He struck out two without walking a batter.

Four of the six hits off Junk went for extra bases, including back-to-back solo shots by Jose Ramirez and Kyle Manzardo in the first inning. The right-hander was taken off the hook for his seventh loss of the season when Miami was able to tie the game at 3-3 in the fifth frame. Junk hasn't recorded an out in the sixth inning since the All-Star break, working exactly five innings in each of his last five starts while stumbling to a 6.84 ERA, 1.40 WHIP and 14:4 K:BB. He could get bumped aside by top prospect Robby Snelling at some point, but for the moment Junk lines up to make his next start on the road this weekend in Boston.

Singer (10-9) picked up the win Tuesday, allowing three hits over six scoreless innings in a 6-1 victory over the Phillies. He struck out six without walking a batter.

The 29-year-old righty retired the first 12 batters he faced and only ran into trouble in his final inning, when a pair of two-out hits put runners at second and third. Singer was able to coax a groundout from Kyle Schwarber to end the threat, however. The quality start was his 10th of the year, and after a rough outing against the Nationals on July 21, Singer's posted a 1.96 ERA, 0.96 WHIP and 26:6 K:BB in 23 innings over his last four trips to the mound. He'll look to keep rolling in his next start, which is scheduled to come on the road early next week against the Angels.
