Chicago Cubs pitcher Shota Imanaga surrendered seven runs on seven hits in six innings on Sunday at Wrigley Field, pushing his ERA to 4.04 and extending the club’s losing streak to eight games. The 7‑5 loss to the Atlanta Braves left Chicago at 29‑124, now 2½ games behind the Milwaukee Brewers and holding the third wild‑card spot in the National League. The defeat also marked the first time this season that the Cubs have been swept in back‑to‑back home series, a slump that echoes a nine‑game slide that ended their 2022 campaign.
For context, the Cubs entered the 2026 season with a roster that blended home‑grown talent—such as third‑baseman Ian Happ and left‑handed reliever Jared Jones—with high‑profile acquisitions. The most significant offseason move was a four‑player trade with the Miami Marlins that sent a package of prospects for veteran catcher Yadier Cabrera. Cabrera, a three‑time All‑Star in Miami, was expected to provide both defensive stability behind the plate and a middle‑of‑the‑order bat. While his .285 average and .375 on‑base percentage in 45 games have been a bright spot, the overall offensive production has been anemic.
Why the slide is widening
Starter inconsistency and a bullpen that has posted a collective ERA above 5.00 this week are the main culprits. Imanaga’s outing mirrored the broader trend: seven runs on seven hits, with two wild pitches that allowed runners to advance into scoring position. His ERA now sits above league average (4.04 vs. NL average 3.71) and marks a regression from his 3.38 mark just a month ago.
The Cubs’ rotation has been a revolving door. Veteran right‑hander Zack Wheeler (3‑2, 4.87 ERA) struggled with command, while left‑hander Jameson Taillon, a former top prospect who made his MLB debut in 2024, posted a 2‑3 record with a 5.12 ERA before being demoted to Triple‑A Iowa. The lack of a reliable third starter has forced manager David Ross to rely heavily on the bullpen, which has been hit hard by a spate of defensive miscues—four errors in the past eight games that have directly led to eight unearned runs.
Defensively, the Cubs rank 12th in the NL in fielding percentage (0.985) but have seen a recent dip in range factor, especially at second base where Ian Happ has logged a .947 fielding percentage—below his career norm of .962. The defensive lapses have turned potential wins into losses, compounding the offensive drought.
Numbers from the eight‑game stretch
During the skid the Cubs have been outscored by an average of 4.2 runs per game, while team OPS+ dropped to 89, well under the NL average of 100. The decline is stark: in the first 15 games of the season the club posted an OPS+ of 102, but since May 1 it has slipped 13 points. The team’s slugging percentage fell from .425 to .382, and runs per game fell from 4.9 to 3.1.
Veteran catcher Yadier Cabrera is batting .285 with a .375 OBP and 22 RBIs, providing a rare consistency in an otherwise erratic lineup. However, his power numbers are limited—only 2 home runs—highlighting the Cubs’ inability to generate extra‑base hits. Outfielder Ian Happ has seen a regression in his power metrics, hitting .258 with a .332 OBP and a wRC+ of 84, well below his career average of 106.
Reliever Jared Jones has been a rare bright spot in the bullpen, posting a 2.68 ERA over 31 innings, but the rest of the staff has been porous. The collective ERA of the non‑starter relievers sits at 5.27, with a WHIP of 1.44. The high‑leverage situation on Sunday—two runners on base with one out—exemplified the bullpen’s struggles, as the relievers allowed three runs in the seventh inning.
Key developments
- The Cubs have been swept in consecutive home series for the first time this season, underscoring the depth of the slump. The previous sweep came at the hands of the Tampa Bay Rays, a team that outlasted Chicago 4‑1 in a tightly contested series.
- Imanaga’s ERA rose from 3.38 to 4.04 after his latest start, marking his highest season ERA to date. His K/9 has dropped from 9.2 to 7.8, indicating a loss of swing‑and‑miss capability.
- Chicago’s eight‑game skid is the longest losing streak since the nine‑game run that ended the 2022 campaign. The 2022 streak coincided with an injury‑plagued roster and a mid‑season managerial change.
- Cabrera, acquired in a four‑player trade with the Marlins, is providing a bright spot with a .285 average and 22 RBIs. His pitch framing metrics rank in the top 15% of NL catchers, improving the staff’s overall strike‑out rate.
- The team now trails the Brewers by 2½ games in the NL Central and sits third in the wild‑card race, tightening the margin for postseason qualification. Milwaukee sits at 31‑122 with a league‑best 1.12 runs per game differential.
Historical perspective
The Cubs’ eight‑game losing streak is the second‑longest in franchise history since 2010, trailing only the 2022 nine‑game slide. In 2015, a seven‑game skid contributed to the Cubs missing the playoffs despite a 97‑win season—a reminder that mid‑season collapses can be costly. Comparatively, the 2023 Dodgers endured a six‑game losing streak but rebounded to capture the NL West, illustrating that a slump is not necessarily fatal if the front office makes timely adjustments.
Coaching strategies and upcoming adjustments
Manager David Ross has hinted at a rotation shuffle for the upcoming series against the St. Louis Cardinals. Ross is expected to give rookie right‑hander Jameson Taillon a spot start on Tuesday, a move designed to buy time for the bullpen and to test Taillon’s durability after his recent injury‑limited stint in Iowa. Ross also plans to insert a defensive shift against left‑handed power hitters, a strategy the Cubs have employed only 18% of the time this season but which analysts from FanGraphs rate as potentially reducing opponent BA by .012.
On the offensive side, hitting coach Mike Matheny is emphasizing a “launch angle” approach, encouraging hitters to elevate the ball more often. Since May 15, the team’s average launch angle has risen from 8.4° to 12.1°, but the resulting hard‑hit rate has only marginally improved from 28% to 31%—still below the NL average of 35%.
Front‑office president Jed Hoyer has been active at the trade deadline, scouting for a left‑handed reliever who can lower the bullpen’s ERA below 4.50. Sources close to the organization say the Cubs are in talks with the Seattle Mariners about acquiring a veteran left‑hander for a prospect and a player to be named later.
What’s next for Chicago?
Chicago Cubs must halt the slide quickly to stay alive in the playoff hunt. The next series begins Tuesday at home against the St. Louis Cardinals, a divisional matchup that could serve as a turning point if the rotation stabilizes and the bullpen trims its ERA below 4.50. A win would cut the streak to seven games and keep the Cubs within a game and a half of the Brewers.
Statistical models from CBS Sports suggest that a two‑game swing in run differential—equivalent to a five‑run inning—raises the Cubs’ wild‑card probability from 31% to 44% over the next 15 games. The models also highlight the importance of limiting walks; Chicago has issued 2.1 BB/9, the highest in the NL, and reducing that figure could lower the bullpen’s inherited‑runner scoring percentage from 32% to under 25%.
Veteran outfielder Ian Happ said the team is “still hungry,” a reminder that morale can shift quickly when a few key at‑bats click. Happ’s recent approach has been to swing more aggressively on fastballs, a change that produced a two‑run double against the Braves on Sunday.
Analyst Tom Verducci of ESPN notes that the Cubs’ next 10 games feature four games against opponents with a sub‑.500 record, offering a realistic path to a positive swing. However, he cautions that the NL Central is tightly packed; the Brewers, Cardinals, and Reds are all within two games of each other, making every series a potential swing‑factor.
How does the Cubs’ eight‑game losing streak compare historically?
The eight‑game slide is the longest since a nine‑game streak in 2022, making it the second‑longest losing run in recent franchise history. Historically, the Cubs have endured longer streaks—most notably a 14‑game skid in 2011—but those seasons ended with the team well out of contention.
What is Shota Imanaga’s career ERA before this season?
Before 2026, Imanaga posted a career ERA of 3.71 over three seasons with the Cubs, indicating that his current 4.04 mark is a notable regression. His FIP has risen from 3.85 to 4.22, suggesting the increase is not solely due to defensive factors.
Did the Cubs’ two 10‑game winning streaks affect their playoff odds?
Those streaks lifted Chicago’s win total to 29 by late May, briefly placing the team within a half‑game of the division leader and raising their wild‑card probability to roughly 48 percent before the recent decline. The subsequent eight‑game slide has since dropped that probability back to the low‑30s.
What role has Yadier Cabrera played since joining Chicago?
Cabrera, acquired from Miami in January, has contributed a .285 average, .375 on‑base percentage and 22 RBIs, offering veteran leadership despite the team’s overall struggles. His framing runs added an estimated +3.2 WAR value, the highest among Cubs catchers this season.
When is the next opportunity for the Cubs to break the streak?
The Cubs host the St. Louis Cardinals on Tuesday, a divisional matchup that could serve as a turning point if the rotation stabilizes and the bullpen trims its ERA below 4.50. A win would also provide a morale boost heading into a four‑game road trip against the Pittsburgh Pirates and Cincinnati Reds.
