Smith came away with a no-decision in Wednesday's 1-0 loss to the Tigers, allowing two hits and three walks over five scoreless innings. He struck out five.

The right-hander put together one of his stingiest performances of the season, although it wasn't exactly efficient as he needed 92 pitches (56 strikes) to record 15 outs. Smith wasn't rewarded for his efforts, however, as the White Sox offense managed only two hits on the afternoon. Smith has looked good since returning from an ankle injury at the beginning of August, giving up four runs in 14.1 innings (2.51 ERA) with a 17:8 K:BB over three starts, but all three resulted in no-decision. He'll look for his first win since June 10 in his next outing, which lines up to come on the road early next week in Atlanta.

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.

Melton (3-1) picked up the win in Wednesday's 1-0 victory over the White Sox, allowing just one hit over five scoreless innings. He struck out six without walking a batter.

Making his first big-league start since July 28, the rookie right-hander retired the first 12 batters he faced before Luis Robert doubled to lead off the fifth inning, but Melton made sure he would advance no further. Despite being on a limited pitch count, Melton lasted long enough to qualify for the win, firing an efficient 56 pitches (43 strikes). The Tigers don't have a vacancy in their rotation, so this was likely just a spot start to buy the team's regular starters some extra rest. Melton will head back to a long-relief role with a 2.82 ERA, 0.85 WHIP and 21:4 K:BB over his first 22.1 MLB innings.

Eflin will undergo back surgery Monday and is expected to be sidelined 4-to-8 months, Matt Weyrich of The Baltimore Sun reports.

Eflin had already been ruled out for the season after it was revealed he would need lumbar microdiscectomy surgery, and now there's a firmer timetable for the right-hander's recovery. The 31-year-old is hopeful the operation will allow him to put his nagging back issues -- which he revealed Wednesday have been a problem off and on for the past 5-to-6 years -- behind him, per Roch Kubatko of MASNSports.com. An impending free agent, Eflin hopes to be ready for the start of spring training, but it's not a given.

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.

The Astros optioned Gordon to Triple-A Sugar Land on Wednesday.

Gordon's latest stint with the big club lasted only one day, as he'll be sent down after yielding five runs (four earned) in a two-inning relief outing Tuesday versus the Red Sox. Jordan Weems is taking Gordon's spot on the roster.

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.
