Lynn allowed one run on five hits and a walk while striking out seven over five innings in a no-decision versus the Reds on Wednesday.

Lynn pitched for the first time since the end of July after missing nearly six weeks with right knee inflammation. He was sharp in his return, throwing 62 of 90 pitches for strikes and limiting the Reds to a Santiago Espinal RBI single in the fourth inning. Lynn has had middling results this year, though he was improving prior to the injury. The 37-year-old is now at a 3.96 ERA, 1.36 WHIP and 104:42 K:BB through 111.1 innings over 22 starts this season. Lynn is projected to make his next start at home versus the Pirates.

Steele (elbow) threw a bullpen session Wednesday, Meghan Montemurro of the Chicago Tribune reports.

This marks the first time Steele has thrown off a mound since he landed on the injured list last Wednesday, and he's slated to throw another bullpen session over the weekend. Assuming everything goes smoothly, the 29-year-old lefty could be cleared to face live hitters sometime next week and appears to have a good chance to pitch again before the end of the season.

Manaea didn't factor into the decision Wednesday against the Blue Jays, allowing one run on three hits and four walks over 6.2 innings. He struck out eight.

Manaea's now gone at least 6.2 innings in six straight starts, posting a 3.07 ERA in that span (41 innings). The left-hander is 11-5 on the season with a 3.35 ERA, 1.10 WHIP and 171 strikeouts (23 shy of a career high) across 164 innings. Manaea's currently lined up to face the Nationals at home next week in his next outing.

Manager Torey Lovullo said Kelly was lifted from Wednesday's start due to right hamstring cramping, but the right-hander is expected to make his next turn through the rotation, Jesse Friedman of GoPHNX.com reports.

Kelly allowed three earned runs over four innings before being lifted from Wednesday's contest, but he doesn't appear to be dealing with a serious injury. The 35-year-old's next turn through the rotation tentatively lines up for Monday in Colorado, and he should be expected to take the mound then unless the hamstring issue lingers.

The Padres placed Perez on the paternity list Wednesday.

Perez is allowed to be away from the team for up to three games, and the Padres will push back his next scheduled start from Friday to Sunday while he spends time with his family, per Jeff Sanders of The San Diego Union-Tribune. While Perez is away, Tom Cosgrove will come up from Triple-A to give San Diego additional bullpen help.

Single-A Palm Beach placed Showalter on its 7-day injured list Aug. 16 with an unspecified injury.

Showalter, 20, posted a 2.62 ERA and 1.26 WHIP with 59 strikeouts over 34.1 innings before being shut down with the injury. The Cardinals appear committed to developing him as a reliever, as he had made each of his 24 appearances out of the bullpen this season.

Kelly was removed from Wednesday's start against the Rangers in the fifth inning with an undisclosed injury, Nick Piecoro of The Arizona Republic reports.

The Diamondbacks should provide an update on Kelly's condition after the game, but he has dealt with cramping multiple times in the past and was seen shaking his leg during a visit from the trainer. Kelly struck out three and was charged with two runs over four-plus innings before being removed.

Falter (8-7) earned the win Wednesday over Miami, allowing two hits and three walks over 7.1 scoreless innings. He struck out five.

Falter was excellent, holding the Marlins to just a pair of singles. The scoreless effort marked Falter's first quality start since June 18 -- he hadn't gone more than 5.2 innings in any of his previous 10 outings, posting a 5.79 ERA in that span. The left-hander's ERA now sits at 4.20 on the season with a 1.27 WHIP and 89:39 K:BB across 128.2 innings. Falter's currently lined up for a road matchup with the Cardinals in his next outing.

The Cardinals activated Lynn (knee) from the 15-day injured list Wednesday.

Lynn will rejoin the rotation Wednesday versus the Reds after missing the last six weeks of action with right knee inflammation. He made one rehab start, allowing five runs over 3.2 innings while throwing 80 pitches for Triple-A Memphis on Sept. 1. The last couple spots in the St. Louis rotation are in flux, so Lynn likely will need to pitch well in order to continue being given additional starts down the stretch.

Snelling has a 3.77 ERA, 1.16 WHIP and 32:10 K:BB in 31 innings across six starts for Double-A Pensacola.

The Marlins acquired Snelling as part of the deadline deal that sent Tanner Scott and Bryan Hoeing to the Padres. The 20-year-old lefty had a mediocre 10.3 K-BB% prior to the trade and has a 17.1 K-BB% since the deal. Snelling is the youngest qualified starter at Double-A and has now logged 100-plus innings in back-to-back minor-league campaigns.
