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 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.

White Sox's Aaron Bummer: Picks up 16th hold
by RotoWire Staff | RotoWire

Bummer tossed two scoreless innings and struck out one in Friday's 7-2 win over the Angels.

The performance earned Bummer his 16th hold of the year. Bummer has allowed two runs on nine hits and two walks across six appearances in August, striking out seven in that span. For the year, the set-up man has a 1.65 ERA and 0.96 WHIP in 49 innings pitched, adding a 42:15 K:BB. He's still unlikely to see many save chances behind closer Alex Colome.

White Sox's Aaron Bummer: No runs allowed in second half
by RotoWire Staff | RotoWire

Bummer walked one in a scoreless two-thirds of an inning in Saturday's 5-1 win over the Twins.

Bummer, who earned his team-leading 11th hold, has not allowed a run and sports a 0.75 ERA over the last 10 games. As the trade deadline approaches, Bummer is in position to take over as the team's closer if the White Sox opt to trade existing closer Alex Colome.

White Sox's Aaron Bummer: Earns 10th hold
by RotoWire Staff | RotoWire

Bummer allowed a solo home run and a walk over two innings to pick up the hold in Sunday's 3-1 win over the Cubs.

Bummer is fitting in quite nicely in the setup role he wrested away from an ineffective Kelvin Herrera, posting a 1.89 ERA with 34 strikeouts over 33.1 innings. The home run was just the second he's allowed in 2019.

White Sox's Aaron Bummer: Has closing stuff per manager
by RotoWire Staff | RotoWire

White Sox manager Rick Renteria feels Bummer can be a closer, David Just of the Chicago Sun-Times reports.

Bummer is having a breakout season in the bullpen, and Renteria made a case for him as an All-Star and a closer Saturday. "He's got good enough stuff to do that," Renteria said of Bummer closing. "I think nobody would mistake that his stuff is lights out. When he's good he can dominate any hitter." Alex Colome has filled the closer's role well for the White Sox, so Bummer's not about to be promoted unless the team falls out of postseason contention and trades Colome. Bummer, who has one save and eight holds, has a 1.95 ERA with one home run allowed and 28 strikeouts over 27.2 innings.

White Sox's Aaron Bummer: Nets first save
by RotoWire Staff | RotoWire

Bummer tossed a scoreless ninth inning to pick up the save against the Yankees on Thursday, allowing one hit while striking out two.

Alex Colome was presumably unavailable after recording a five-out save Wednesday, so Bummer got the nod to finish things off. The 25-year-old did so in strong fashion, blanking the Yankees to pick up his first save in the big leagues. Through 18 appearances, Bummer owns a 1.37 ERA, 0.71 WHIP and 20:5 K:BB.

White Sox's Aaron Bummer: Preserves Giolito's win
by RotoWire Staff | RotoWire

Bummer got the only batter he faced to earn his fourth hold in Saturday's 2-0 win over the Royals.

Bummer came on to mop up the eighth for Lucas Giolito and held the fort for closer Alex Colome to save the game. It was the second straight Giolito start in which Bummer entered the eighth inning with men on and held the lead. Bummer has allowed one earned run over 17.1 innings and moved into a prominent bullpen role.

White Sox's Aaron Bummer: Pitches in setup role
by RotoWire Staff | RotoWire

Bummer worked around a walk in one-third of an inning to record his second hold in Monday's 5-2 win over the Indians.

Bummer was used as the bridge from starter Reynaldo Lopez to closer Alex Colome, a nod to the good work he's done since being called up from Triple-A Charlotte. He's allowed two hits and two walks over 9.1 scoreless innings since his promotion and appears to be in the mix for high-leverage and setup work. The eighth inning had been the domain of Kelvin Herrera, but he's allowed runs in six of his last 10 appearances, a stretch that includes 14 hits, six walks and 10 runs allowed.

White Sox's Aaron Bummer: No earned runs allowed
by RotoWire Staff | RotoWire

Bummer struck out one in a perfect inning in Sunday's 5-1 win over the Blue Jays.

Bummer has been an effective reliever for the White Sox since his callup from Triple-A Charlotte. He's allowed just one unearned run, two hits and one walk over nine innings.

White Sox's Aaron Bummer: Joins big-league club
by RotoWire Staff | RotoWire

Bummer was recalled from Triple-A Charlotte on Sunday.

Bummer will get his first taste of the major leagues this season after Nate Jones (elbow) and Eloy Jimenez (ankle) were placed on the injured list. He has pitched well at Triple-A Charlotte, recording a 2.35 ERA across 7.2 innings of work.

White Sox's Aaron Bummer: Optioned to Triple-A
by RotoWire Staff | RotoWire

Bummer was optioned to Triple-A Charlotte on Monday.

Bummer seemed to have a shot at a bullpen role but will have to make the case for a roster spot during his time in the minors. His 12.00 ERA in six spring innings can't have helped him as he pushed for a job.

White Sox's Aaron Bummer: Joins big-league club
by RotoWire Staff | RotoWire

Bummer was recalled from Triple-A Charlotte on Saturday.

Bummer last saw the majors in early June and had a solid 3.26 ERA and 21:6 K:BB over 19.1 innings. The 24-year-old did allow a .321 opponent batting average and a 1.71 WHIP, which suggests some regression is likely in order. The 24-year-old could be used as a situational left-hander for the White Sox.

White Sox's Aaron Bummer: Sent to minors
by RotoWire Staff | RotoWire

Bummer was optioned to Triple-A Charlotte on Wednesday, Daryl Van Schouwen of the Chicago Sun-Times reports.

The White Sox are expected to announce a corresponding roster move prior to Thursday's series finale against the Twins. Bummer owns a solid 3.26 ERA and 21:6 K:BB across 19.1 innings this season, so he'll likely be back with the big club when a fresh reliever is needed.

White Sox's Aaron Bummer: Kept away from righty hitters
by RotoWire Staff | RotoWire

Bummer pitched a third of an inning and uncorked a wild pitch in Friday's 7-4 extra-inning win over the Royals.

The wild pitch allowed Whit Merrifield to score and moved Mike Moustakas to second base, setting the stage for him to score the tying run later in the inning. If possible, the White Sox are limiting Bummer to left-handed batters only, as was the case Friday when he was brought on to face Lucas Duda. He's faced one batter in each of his last three outings. The 24-year-old southpaw is limiting lefty hitters to a .563 OPS while righties are at .839 this season.

White Sox's Aaron Bummer: Gets Opening Day roster spot
by RotoWire Staff | RotoWire

The White Sox will include Bummer in their bullpen when their season opens Thursday against the Royals, Daryl Van Schouwen of the Chicago Sun-Times reports.

With a 3.60 ERA and 13 strikeouts over 10 innings in Cactus League play, Bummer did enough to beat out Robbie Ross for one of the final openings in the bullpen. Though the White Sox are short on quality relief talent, Bummer isn't expected to ascend quickly in the bullpen hierarchy after largely failing to impress in his 30 appearances with the big club a season ago. The lefty finished with a 4.50 ERA and 17:15 K:BB across 22 innings.

White Sox's Aaron Bummer: Throws scoreless inning Wednesday
by RotoWire Staff | RotoWire

Bummer pitched a clean inning of relief in Wednesday's game against the Padres.

Bummer finished up the 2017 season as a bullpen regular, but the left-hander faces competition this spring from the recently signed Robbie Ross. That the White Sox felt the need to add Ross suggests Bummer is not guaranteed a spot.

White Sox's Aaron Bummer: Part of failed closer committee
by RotoWire Staff | RotoWire

Bummer allowed a hit to the only batter he faced in the ninth inning of Wednesday's 5-4 loss to the Dodgers. He was charged with an earned run.

This was the White Sox's first save opportunity since they traded Tyler Clippard, so we watched with some interest. Manager Rick Renteria tried to navigate the inning by matching up right-on-righty and lefty-on-lefty. Bummer entered the game after Gregory Infante to face Cody Bellinger, who delivered a single and came around to score on a hit allowed by Jake Petricka. None of the closing candidates are inspiring and if Renteria continues to play the matchup game, fantasy owners are left hoping that a given matchup favors them.

White Sox's Aaron Bummer: Summoned to majors
by RotoWire Staff | RotoWire

The White Sox called up Bummer from Triple-A Charlotte on Thursday, Colleen Kane of the Chicago Tribune reports.

The 23-year-old left-hander compiled a solid 3.00 ERA in 33 innings with Double-A Birmingham, accompanied by 34 strikeouts and 16 walks. Bummer will occupy a depth role for a club suddenly lacking reliable high-leverage relievers, considering the White Sox traded David Robertson, Tommy Kahnle, Anthony Swarzak and Dan Jennings in the last week or so.
