White Sox's Aaron Bummer: Retires all five batters
by RotoWire Staff | RotoWire

Bummer struck out three over 1.2 scoreless innings in Sunday's 9-3 win over the Royals.

Bummer retired all five batters faced and has sorted out the mechanical issues that bedeviled him early in the season. He's thrown six straight scoreless outings, spanning six innings, and hasn't walked a batter during that stretch. The setup man had opened the season with six walks over 5.1 innings (seven appearances).

White Sox's Aaron Bummer: Fighting mechanics
by RotoWire Staff | RotoWire

Bummer struck out two over a scoreless inning in Saturday's 7-3 win over Cleveland.

The White Sox's bullpen, projected as a strength entering the season, posted a 4.50 ERA and blew seven saves during April. Bummer has not been excluded from the struggles. He told Jared Wyllys of the Chicago Sun-Times that a dropoff in his performance this season is due to a mechanical issue. Bummer's strikeouts are down and walks up thus far in 2021, but he still has a respectable 2.08 ERA over 8.2 innings.

White Sox's Aaron Bummer: Tagged with Opening Day loss
by RotoWire Staff | RotoWire

Bummer (0-1) allowed two unearned runs on two hits and one walk while striking out one over two-thirds of an inning to take the loss against the Angels on Thursday.

Holding a one-run lead entering the eighth inning, the White Sox were set up for a season-opening win and the debut of new closer Liam Hendricks, but Bummer couldn't work around a couple of fielding miscues. On a fielder's choice, Nick Madrigal's throw drew Tim Anderson off the second-base bag, then a Yasmani Grandal passed ball advanced the runners. A single, a walk and a sacrifice fly later, and Opening Day went from a delight to, well, a bummer. Bummer's been stellar out of the bullpen for the White Sox the previous two seasons and has earned the role as a setup man.

White Sox's Aaron Bummer: Makes Cactus League debut
by RotoWire Staff | RotoWire

Bummer allowed two runs on one hit and two walks while striking out two in two-thirds of an inning during Thursday's spring game against the Reds.

This was Bummer's debut this spring. The left-hander has been a high-leverage contributor out of the bullpen, emerging as Chicago's primary setup man during a breakout 2019 campaign. A biceps injury limited him in 2020, but he returns as a setup option from the left side in front of closer Liam Hendriks.

White Sox's Aaron Bummer: Throws in 'B' game
by RotoWire Staff | RotoWire

Bummer threw a perfect inning in a "B" game Sunday against the Dodgers, Scott Merkin of MLB.com reports.

Bummer faced opponents for the first time this spring in what turned out to be a bullpen day against the Dodgers. "I was happy to get out there and face their hitters, work on things, throw to [Jonathan] Lucroy and get more familiar with him," Bummer said. "Overall a good day for the first time. Hopefully getting into a game soon." Bummer arrived to camp late after staying back for the birth of a child. That put him slightly behind others, but the left-hander has plenty of time to get ready for the regular season. He's expected to be the primary setup man for closer Liam Hendriks.

White Sox's Aaron Bummer: Arrives late to camp
by RotoWire Staff | RotoWire

Bummer arrived late to spring training but is not behind other pitchers, Scott Merkin of MLB.com reports.

Bummer was with his wife for the birth of their first child and missed the beginning of camp, but knowing his daughter's delivery date was scheduled near the start of spring training, he went to Arizona during January and worked out a specific routine with the training staff. "Everything feels good. I feel pretty confident with where I'm at, that I'm not behind and I'm really right where I want to be," said the pitcher. Bummer, who had a biceps injury that limited him to nine games in 2020, is expected to serve as a top setup man in the White Sox's bullpen.

White Sox's Aaron Bummer: Scoreless in return
by RotoWire Staff | RotoWire

Bummer allowed a hit and struck out one over a scoreless eighth inning in Thursday's 5-4 loss to Cleveland.

Bummer was activated from the injured list earlier in the day and resumed his role as the White Sox's eighth-inning bridge to closer Alex Colome. Unfortunately, two relievers before him conspired to give away Chicago's three-run lead in the seventh inning, and Bummer's appearance took on less significance.

White Sox's Aaron Bummer: Back from biceps injury
by RotoWire Staff | RotoWire

Bummer (biceps) was reinstated from the 45-day injured list prior to Thursday's game against Cleveland.

This is encouraging, as there were no guarantees Bummer would make it back this season. He last pitched in a game Aug. 7 and had an impressive 1.23 ERA, 1.09 WHIP and 12:4 K:BB in 7.1 innings before suffering the injury. Look for him to quickly work his way back into the setup mix in advance of the postseason.

White Sox's Aaron Bummer: Looks good in throwing session
by RotoWire Staff | RotoWire

Bummer (biceps) threw 20 pitches in a simulated game Saturday, James Fegan of The Athletic reports.

Manager Rick Renteria said that Bummer looked good during his throwing session in Cincinnati on Saturday. Assuming his biceps respond well, Bummer could make his return prior to the end of the regular season as the White Sox gear up for a playoff run.

White Sox's Aaron Bummer: Could return next weekend
by RotoWire Staff | RotoWire

Bummber (biceps) could be activated off the injured list during the White Sox's final road trip of the season, which begins Sept. 18 in Cincinnati, Scott Merkin of MLB.com reports.

The left-hander has been on the shelf since early August due to the left biceps strain and subsequent nerve issue, but he appears to be closing in on a return. Bummer allowed only one run with a 12:4 K:BB over 7.1 innings to begin the season and had a 2.13 ERA and 0.99 WHIP with 27 holds in 2019, so he could provide a significant boost to the bullpen for the closing stretch.

White Sox's Aaron Bummer: Transferred to 45-day IL
by RotoWire Staff | RotoWire

Bummer (biceps) was transferred to the 45-day injured list Saturday.

Bummer will shift to the 45-day IL to clear a spot on the 40-man roster as he deals with a nerve issue near his biceps. The southpaw could still return prior to the end of the season, but his status depends on how the nerve issue responds to his throwing program.

White Sox's Aaron Bummer: Has nerve issue
by RotoWire Staff | RotoWire

Bummer's biceps muscle has healed, but he's now dealing with a nerve issue near the biceps, Scott Merkin of MLB.com reports.

White Sox general manager Rick Hahn explained that this is not a long-term issue but acknowledged the possibility that Bummer may not return in the shortened 2020 season. "It really comes down to getting that nerve calmed down and then as we ramp him up, which we have started to do on a throwing program, how the nerve responds. It's quite possible, based on how the throwing program lays out, that you see us at some point put him on the 45-day IL," said Hahn. With Bummer sidelined, Evan Marshall has picked up a majority of the setup work in front of closer Alex Colome.

White Sox's Aaron Bummer: Playing catch
by RotoWire Staff | RotoWire

Bummer has progressed to playing catch at the team's alternate training site, James Fegan of The Athletic reports.

Bummer has been on the injured list since Aug. 8 with left biceps soreness, so the report that he is starting to throw is encouraging in terms of his rehab progress. There is still no timeline for his official return, and one likely won't be set until he starts throwing off a mound.

White Sox's Aaron Bummer: Not throwing yet
by RotoWire Staff | RotoWire

White Sox manager Rick Renteria said Tuesday that Bummer's biceps is "loosening up," but the lefty has yet to begin a throwing program, Scott Merkin of MLB.com reports.

The White Sox have been encouraged with how Bummer has bounced back from the left biceps strain after landing on the 10-day injured list Saturday, but a target date for his return probably won't be established until he's cleared to resume mound work. Before getting shut down with the injury, Bummer had served as Chicago's top setup man, giving up one earned run on four hits and four walks over 7.1 innings while striking out 12 and collecting three holds.

White Sox's Aaron Bummer: Placed on 10-day injured list
by RotoWire Staff | RotoWire

Bummer (biceps) was placed on the 10-day injured list Saturday.

Bummer was removed from Friday's win against Cleveland after throwing 30 pitches and will miss several games as a result of a left biceps strain. The southpaw had been dominant out of the bullpen for the White Sox to begin the season, recording a 1.23 ERA and 12:4 K:BB over 7.1 innings across seven appearances. Evan Marshall and Steve Cishek could see an uptick in higher-leverage opportunities while Bummer is sidelined.

White Sox's Aaron Bummer: Dealing with left biceps soreness
by RotoWire Staff | RotoWire

Bummer was diagnosed with left biceps soreness following his removal from Friday's game.

Bummer is set to be re-evaluated by the White Sox on Saturday, after which the team could get a better idea of the severity of the issue. The southpaw pitched 1.2 scoreless innings Friday prior to his removal, allowing one hit and two walks while failing to record a strikeout.

White Sox's Aaron Bummer: Exits with apparent injury
by RotoWire Staff | RotoWire

Bummer was removed from Friday's game with an apparent injury, Scot Gregor of the Chicago Daily Herald reports.

Bummer entered in the sixth inning of Friday's contest and threw 30 pitches over 1.2 innings, but he was examined by the training staff and removed from the game. The nature and severity of the injury are unclear.

White Sox's Aaron Bummer: Picks up first win
by RotoWire Staff | RotoWire

Bummer (1-0) struck out two over a scoreless eighth inning and was credited with the win in a 4-0 victory over Cleveland.

Bummer was the pitcher of record when the White Sox plated four runs in the top of the ninth inning. The left-hander was one-fourth of the White Sox's best-pitched game of the season. No. 1 starter Lucas Giolito gave them six strong innings followed by Evan Marshall, Bummer and Alex Colome. Bummer earned his role as a setup man in 2019 when he posted a 2.13 ERA over 67.2 innings.

White Sox's Aaron Bummer: Nails down bullpen spot
by RotoWire Staff | RotoWire

Bummer is considered a lock to make the White Sox's bullpen, Scott Merkin of MLB.com reports. He's struck out five and walked two with no hits allowed over four scoreless spring innings.

Bummer is the poster child for spring-training stats don't matter. After surrendering nine runs and 11 hits in six spring innings during the 2019 Cactus League, he became the White Sox's most reliable reliever in the regular season. He claimed the setup role from Kelvin Herrera and earned 27 holds while posting a 2.13 ERA. The White Sox were so impressed, they re-signed the left-hander to a five-year deal in February. Bummer from the left and Steve Cishek from the right give opposing batters different looks in the late innings.

White Sox's Aaron Bummer: Lands extension with White Sox
by RotoWire Staff | RotoWire

Bummer signed a five year, $16 million contract extension with the White Sox on Saturday, Bob Nightengale of USA Today reports.

Bummer was effective in 2019 while serving as the setup man for the White Sox as he recorded a 2.13 ERA and 0.99 WHIP over 67.2 innings. While the southpaw's fantasy impact could be limited behind closer Alex Colome and newly acquired Steve Cishek, Bummer will look to build on his impressive campaign in 2020.
