The Cubs recalled Wicks from Triple-A Iowa to serve as the 27th man for Game 2 of Tuesday's doubleheader against the Brewers.

The left-hander will come up to provide some bullpen help for Tuesday's nightcap. Wicks has made just four appearances in the big leagues this year and has given up nine earned runs over 8.1 innings, though he has a 3.62 ERA in 17 outings (14 starts) for Iowa.

The Marlins recalled Gibson from Triple-A Jacksonville on Tuesday.

The left-hander has spent the past 10 days at Triple-A but will rejoin the Marlins with Anthony Bender (lower leg) landing on the injured list. Gibson has recorded four holds with a 3.38 ERA, 1.30 WHIP and 26:11 K:BB across 34.2 major-league innings this season.

The Marlins placed Bender on the 15-day injured list Tuesday due to a right tibial stress reaction.

The right-hander made his last appearance Sunday in Boston and fired a scoreless inning to pick up a save, but he'll now be unavailable for at least the next couple weeks. Calvin Faucher, Ronny Henriquez and Lake Bachar should continue to share closing duties for Miami while Bender is sidelined.

The Phillies designated Walker for assignment Tuesday.

The left-hander has been at Triple-A Lehigh Valley since being acquired from the Blue Jays in May, but Walker will lose his place on the Phillies' 40-man roster without getting a look in the majors. He made 23 relief appearances at Lehigh Valley and had a 4.50 ERA, 1.42 WHIP and 22:12 K:BB across 26 innings.

The Phillies optioned Hoffman to Triple-A Lehigh Valley on Tuesday.

The right-hander was promoted Monday and will return to Lehigh Valley after giving up three runs over an inning against the Mariners in his MLB debut. Jose Alvarado (suspension) was reinstated to round out Philadelphia's active roster.

The Phillies reinstated Alvarado (suspension) from the restricted list Tuesday.

The left-hander has been sidelined since mid-May after being handed an 80-game suspension for a positive PED test, but he'll rejoin the Phillies for the closing stretch of the regular season. Alvarado was part of the closing mix prior to the suspension with seven saves and a 2.70 ERA, but Jhoan Duran is now locked in as Philadelphia's closer. Due to the suspension, Alvarado won't be eligible to pitch in the playoffs this season.

Hall (oblique) is expected to be sidelined until mid-September, Todd Rosiak of the Milwaukee Journal Sentinel reports.

Hall was placed on the 15-day injured list this past weekend after suffering a mild right oblique strain. He will be shut down until late August before beginning a throwing program, provided his symptoms subside. Hall has been used as a multi-inning reliever, so it will take a bit for him to be built back up once he's throwing again.

Walker picked up a hold in Monday's 4-3 win over San Diego, allowing two hits while striking out one over 1.1 innings.

Walker entered the game with two outs in the seventh, surrendering a single before escaping the inning. The right-hander gave up another single to the first batter he faced in the eighth but followed it with a strikeout before inducing an inning-ending double play. He threw 13 of his 17 pitches for strikes en route to his first hold since June 27. Over six appearances in August, Walker has recorded a 1.50 ERA, 1.33 WHIP and a 4:1 K:BB across six innings.

The Cubs optioned Hollowell to Triple-A Iowa on Monday, Maddie Lee of the Chicago Sun-Times reports.

He was technically up as the 27th man for what was supposed to be a doubleheader Monday versus the Brewers, though the second game got rained out. Hollowell was roughed up for four runs over two innings in the first game Monday and is now headed back to Iowa.

The Cubs recalled Cosgrove from Triple-A Iowa on Tuesday, Maddie Lee of the Chicago Sun-Times reports.

Cosgrove will join the Cubs ahead of Tuesday's doubleheader with the Brewers, though it's unclear if he or another player will be sent back to Iowa once the twin bill concludes and Chicago needs to reduce its active roster to 26 men. The 29-year-old southpaw reliever has made just two appearances in the majors this season but has seen ample usage for Iowa, logging a 4.66 ERA and 1.65 WHIP while striking out 47 batters across 38.2 innings over 33 outings.
