White Sox Add Veteran Reliever Javy Guerra on Minor League Deal

The Chicago White Sox made a low-risk bullpen addition on Saturday, signing veteran right-hander Javy Guerra to a minor league contract. The move adds experienced depth to the organization’s pitching pipeline as the club continues to evaluate options for its relief corps.

Guerra will report to Triple-A Charlotte after being released earlier in the week by the Atlanta Braves’ affiliate, the Gwinnett Stripers. The transaction marks another stop in a career that has taken the 30-year-old reliever across multiple leagues and organizations.

Once considered a promising bullpen arm with major league experience, Guerra now finds himself working to re-establish consistency after an uneven stretch of performances in recent seasons. His career has included both strong international success and recent struggles at the Triple-A level.

For Chicago, the signing represents an opportunity to evaluate a veteran arm who has shown flashes of effectiveness in both MLB and Japan, while providing organizational depth as the season progresses.

1. International Success and Career Path

Guerra’s most productive recent season came in Japan’s Nippon Professional Baseball, where he pitched for the Hanshin Tigers in 2024. There, he posted a strong 1.55 ERA over 58 innings and earned 14 saves, establishing himself as a reliable late-inning option. During that standout year, he also demonstrated improved command, significantly reducing his walk rate to 4.9 percent. That level of control marked one of the best stretches of his professional career and helped solidify his role in the Hanshin bullpen. However, his follow-up season in Japan was limited, as he appeared in only six games. The reduced workload signaled a step back in usage and preceded his return to affiliated baseball in the United States. Guerra re-entered MLB systems in January when he signed a minor league deal with the Atlanta Braves, aiming to use his international experience as a springboard back to the major leagues.

2. Struggles in Atlanta Organization

Guerra’s stint with Atlanta’s Triple-A affiliate did not yield the results he hoped for. With the Gwinnett Stripers, he posted a 5.68 ERA across 25.1 innings, struggling to consistently command the strike zone. In 16 appearances, he allowed a 1.78 WHIP while striking out 17 batters and issuing 20 walks. The elevated walk total proved to be a key factor in his overall inconsistency during the stretch. His difficulties carried into spring training, where he allowed five earned runs in just 2 2/3 innings. That performance further complicated his bid to secure a more stable role within the Braves’ system. Ultimately, Atlanta released him earlier this week, making him a free agent before the White Sox moved quickly to add him to their organizational depth chart.

3. New Opportunity in Chicago System

The White Sox will send Guerra to Triple-A Charlotte, where he will have an opportunity to reset and work on regaining form in a lower-pressure environment. The organization has not indicated an immediate timeline for a potential major league call-up. Chicago’s decision to sign Guerra aligns with a common strategy of targeting experienced relievers on minor league deals, particularly those with prior major league exposure and international success. Across his MLB career, Guerra has appeared in parts of five seasons, most notably with the San Diego Padres. His most recent major league action came in 2023 with the Tampa Bay Rays. For now, his focus will be on stabilizing his command and rediscovering the effectiveness that once made him a reliable bullpen contributor at both the major league and international levels.
