Graterol (hamstring) threw a 30-pitch bullpen session Wednesday, Bill Plunkett of The Orange County Register reports.

Graterol threw his first bullpen session Saturday, and he appears to have already built up to a proper reliever's workload. The 26-year-old remains on track to begin a rehab assignment over the weekend, though it's still unclear how many minor-league innings he'll need to pitch before returning to Los Angeles' bullpen.

The Marlins optioned Bermudez to Triple-A Jacksonville on Wednesday, Christina De Nicola of MLB.com reports.

Miami selected the left-hander's contract from Jacksonville over the weekend, and he'll return to Triple-A after giving up two runs over 3.2 frames of long relief during Tuesday's contest. Bermudez had a 6.46 ERA over 23.2 innings for Jacksonville this season, and he's unlikely to see anything more than low-leverage opportunities down the stretch for the Marlins, if he even rejoins the MLB roster.

The Marlins recalled Kitchen from Triple-A Jacksonville on Wednesday, Christina De Nicola of MLB.com reports.

The 27-year-old was sent to Jacksonville in early August and will rejoin the major-league bullpen for the final stretch of the month. Kitchen has made just one appearance in the big leagues and has a 2.96 ERA, 1.15 WHIP and 31:13 K:BB over 48.2 innings across three minor-league levels this season.

Roberts was lifted from Wednesday's appearance against the Pirates in the fourth inning due to right ankle soreness, Maddie Lee of the Chicago Sun-Times reports.

Consider the reliever day-to-day for the time being. Roberts was charged with two runs over 1.1 innings in the appearance before being pulled.

The Reds optioned Legumina to Triple-A Louisville on Wednesday.

Legumina's latest stint in the big leagues lasted just one day, and he yielded one run over a two-inning relief appearance. Evan Kravetz was called up from Triple-A to take Legumina's spot on the active roster and in the bullpen.

The Nationals recalled Ribalta from Triple-A Rochester on Wednesday, Andrew Golden of The Washington Post reports.

Washington placed Joan Adon (bicep) on the 15-day injured list in a corresponding move. Ribalta, 26, permitted three runs over two innings in two appearances with the big club earlier this month.

The Nationals placed Adon on the 15-day injured list Wednesday with a right biceps strain, Andrew Golden of The Washington Post reports.

Adon hasn't pitched in nearly a week, so it's unclear when he might have gotten injured. The right-hander has posted a 6.75 ERA and 6:4 K:BB over 10.2 frames for the Nationals this season. Orlando Ribalta was recalled from Triple-A Rochester to take Adon's spot in the bullpen.

Roberts was removed from an appearance versus the Pirates on Wednesday in the fourth inning with an apparent injury, Meghan Montemurro of the Chicago Tribune reports.

Roberts retired the final batter in the bottom of the second inning and got through a scoreless third inning. However, he gave up a home run, hit a batter with a pitch and surrendered a single in the fourth before being visited by the trainer and exiting the field. It's unclear what injury he's dealing with, but the Cubs should provide an update soon. Roberts was charged with two runs over 1.1 frames before being lifted.

Estrada allowed one hit in a scoreless inning to notch a hold against the Cardinals on Tuesday.

Estrada handled the seventh inning and needed just eight pitches to retire the side despite giving up a one-out single. The right-hander hadn't picked up a hold since July 26 prior to Tuesday, and he's had a somewhat rough August with a 6.23 ERA and 1.85 WHIP over 10 appearances, though he's also posted a 17:5 K:BB across just 8.2 frames during that span.

Jefferies (elbow) threw a live batting practice session earlier this week and is expected to begin a rehab assignment soon, Noah Hiles of the Pittsburgh Post-Gazette reports.

Jefferies has been sidelined since early July with right elbow inflammation but is finally ready to test things out in a game setting. Given the length of his absence, he figures to require a handful of rehab appearances before being considered for the Pirates' active roster.
