The Chicago Cubs currently lead the NL Central, bolstered by the steady performance of starting pitcher Matthew Boyd. Despite injuries sidelining key rotation members, Boyd has excelled, notably in his recent game against the Pittsburgh Pirates, where he allowed just one hit over six innings. Manager Craig Counsell praised Boyd's contributions, highlighting his ability to keep the Cubs competitive. Boyd's impressive home record of 6-0 and a 2.25 ERA at Wrigley Field underscores his importance to the team during this challenging period.

Having undergone Tommy John surgery in 2023, Boyd returned to action with the Cubs and has shown remarkable resilience. His versatility as a pitcher, utilizing various pitches effectively, has made him a reliable asset for the Cubs. Shortstop Dansby Swanson noted Boyd's professionalism and skill, emphasizing the team's confidence when he takes the mound. Boyd's ability to pick off baserunners has also made headlines, as he is currently leading the MLB with six pickoffs this season, showcasing his strategic prowess on the field.

Chicago Cubs manager Craig Counsell continues to navigate the complexities of managing a bullpen that has undergone significant changes. He acknowledges the ever-evolving nature of relievers and how success can be fleeting. Since May 14, the Cubs' bullpen has showcased its resilience, posting an impressive 0.82 ERA over 24 games, notably highlighted by Brad Keller's excellent performance since joining the team.

Keller leads the relievers with a 1.99 ERA and has become a key figure in the late innings, particularly since stepping into a more defined role following injuries to others. Daniel Palencia has stepped up as the closer, while the entire bullpen operates with an impressive cohesiveness that has alleviated pressure on the starting rotation. As the season progresses, maintaining momentum will be crucial for the Cubs’ postseason aspirations.

Shota Imanaga's left hamstring strain during the Chicago Cubs' 4-0 loss to the Milwaukee Brewers raises concerns for an already beleaguered pitching rotation. Imanaga, who previously experienced leg cramps, felt discomfort while covering first base on a double play attempt. Cubs manager Craig Counsell indicated that further imaging would be necessary to assess the injury. With Imanaga potentially joining Justin Steele and Javier Assad on the injured list, Chris Flexen or Cade Horton may be called up to fill the gap.

The Cubs also faced injury concerns with star outfielder Kyle Tucker, who appeared to tweak his hip during a play but remained optimistic about his availability for the upcoming series against the San Francisco Giants. The Brewers, too, dealt with injuries as Sal Frelick exited with left knee discomfort. With the season's demands escalating, teams must strategically navigate these injury challenges.

The Chicago Cubs are strategizing ahead of the MLB trade deadline, particularly focusing on bolstering their starting rotation due to significant injuries. Notably, their interest is directed towards Sandy Alcantara from the Miami Marlins, a former Cy Young award winner. This potential trade carries risk, as Alcantara is recovering from Tommy John surgery that sidelined him for the entire 2024 season. His performance in 2025 has raised concerns, especially with an alarming 8.31 ERA in his first six starts, the highest of his career.

Despite the risk, acquiring Alcantara could significantly enhance the Cubs' rotation, especially with Justin Steele out for the year and Javier Assad facing rehabilitation setbacks. While the Cubs possess a wealth of top prospects to facilitate a trade, Alcantara's inconsistent performance, including a disastrous outing against the Los Angeles Dodgers, poses a dilemma for the team. They hope he can revert to his exceptional 2022 form when he posted a 2.28 ERA with 207 strikeouts over 228.2 innings.

The Chicago Cubs face a significant setback as starting pitcher Justin Steele will miss the entire 2025 season due to reconstructive elbow surgery. Steele has been a reliable presence in the rotation, posting a 3.10 ERA since becoming a full-time starter in 2022. With the loss of their All-Star pitcher so early in the season, the Cubs are contemplating potential internal replacements, including ace Shota Imanaga and veterans Jameson Taillon and Matthew Boyd.

Javier Assad, who impressed last season but is currently on a rehab assignment, could be a crucial returnee to stabilize the rotation. Jordan Wicks, the Cubs' first-round pick from 2021, may also get another chance, despite previous injuries. Cade Horton, their 2023 first-round pick, is performing well at Triple-A and could be called up if needed. For a team aiming for postseason success, filling Steele's void is crucial as they explore both internal options and potential trades.
