The Pittsburgh Pirates finished a recent six-game stretch against the Atlanta Braves and Los Angeles Dodgers with a 1-5 record, highlighting a significant gap in consistency between the club and top-tier National League contenders. According to team data, the Pirates maintained a minus-17 run differential during the series, struggling with defensive miscues, pitching execution, and a 6-for-29 performance with runners in scoring position.
Why Pitching Execution Remains the Primary Hurdle
The core of Pittsburgh’s recent struggles rests on the mound, specifically the performance of starter Mitch Keller. According to manager Don Kelly, Keller has faced difficulty with two-strike execution, contributing to an 8.70 ERA over his last six starts. During a recent outing, Keller utilized his sinker—a pitch intended to induce weak contact—only 13% of the time, falling below his season average of 16%.

The Dodgers’ offense capitalized on this, forcing Pirates pitchers to throw 592 pitches over three days. For the Pirates to return to the form they displayed during the first six weeks of the season, coaches emphasize that starters must prioritize simple, high-percentage pitches over complex pitch-mix strategies. The team currently holds a 5.11 team ERA since May 15, a mark that ranks sixth-worst in Major League Baseball.
How Roster Depth Influences Winning Trends
The Pirates are attempting to bridge the production gap caused by injuries to key players like Oneil Cruz and Konnor Griffin. While the club has relied on internal reinforcements, the results have been mixed. Recent call-ups have provided sparks, such as Tyler Callihan, who is batting .579 with two homers and three extra-base hits in his limited appearances, and Rafael Flores Jr., who recently recorded a 440-foot home run.
According to Kelly, the ability to win while missing core contributors is a hallmark of the Braves and Dodgers, both of whom utilize deep systems to weather injuries. The Pirates’ future success depends on whether these bench contributors can maintain their production while the team waits for its injured stars to return. Spencer Horwitz, who recently extended his on-base streak to 17 games, serves as a primary example of the consistent offensive output the club requires to remain competitive.
What Fundamental Adjustments Are Required?
Beyond individual stats, the difference between the Pirates and the league’s top teams lies in fundamental baseball operations. During the recent series, the Pirates recorded eight walks, hit three batters, and threw two wild pitches in a single game. According to Lowe, the team’s recent losses were compounded by a lack of defensive crispness, including missed tags and errors on routine plays.
