Boston Red Sox are set to promote top infield prospect Marcelo Mayer following Alex Bregman's injury, which occurred on May 24. Mayer, drafted fourth overall in 2021, boasts an impressive performance in Class AAA Worcester, achieving 43 RBIs in as many games this season. Although primarily a shortstop, Mayer has also played at second and third base. His power-hitting ability and strong arm make him a versatile asset for the Red Sox infield, which has been reshuffled due to injuries and positional changes this season.

Rafael Devers shifted to designated hitter after Bregman's arrival, while Trevor Story's struggles at shortstop (.607 OPS) left Boston in need of solid infield support. With Mayer's promotion, the Red Sox are looking to enhance their lineup, especially after first baseman Triston Casas was lost for the season. Additionally, outfielder Roman Anthony, regarded as the top prospect by MLB.com, is also on the rise, hinting at a promising future for Boston's young talent.

The Boston Red Sox have decided to call up infielder Marcelo Mayer, the highly touted No. 6 prospect in baseball, as they aim for a postseason berth. Mayer, who has made a strong impression at Triple-A Worcester, is coming off a solid season where he hit .271 with nine homers and 43 RBIs in just 43 games.

His arrival coincides with the anticipated injury to Alex Bregman, who is likely to be placed on the injured list due to quadriceps tightness. Mayer's versatility allows him to play both shortstop and third base, providing a much-needed boost to the Red Sox lineup, especially in light of the recent injury to Triston Casas. Mayer is projected to become a key part of the team's future, potentially solidifying their middle of the order for years to come.

The Oakland Athletics have begun to express their frustration with their temporary home in Sacramento, particularly regarding the design and layout of Sutter Health Park. Manager Mark Kotsay recently highlighted a crucial missed call during a game against the Los Angeles Angels, which he attributed to his inability to see plays along the left field line due to the stadium's structure. This incident was compounded by the team's performance, suffering a ninth consecutive loss that dropped their record at home to 8-17.

Pitcher Luis Severino has also voiced concerns, arguing that the outfield clubhouses disrupt his routine, stating it's a significant hindrance for most pitchers. Meanwhile, rookie Lawrence Butler commented on the disparity between debuting in a major league park versus the current setup, indicating an atmosphere that falls short of baseball's highest standard. With the A's scheduled to remain in Sacramento through 2027, frustrations are likely to continue if conditions do not improve.

As the MLB season progresses, fantasy baseball managers are keenly focused on the upcoming two-start pitchers for the week of May 26. Notable names like Joe Ryan and Jacob deGrom are set to take the mound twice, providing significant opportunities for fantasy points. Ryan boasts a solid 2.68 ERA and has shown resilience, especially following a rough start earlier in the season. DeGrom, meanwhile, has been adapting his approach and continues to deliver strong performances despite slightly reduced velocity.

Other pitchers to consider include Kevin Gausman and Gavin Williams, both of whom are expected to face competitive lineups. Gausman has demonstrated improved command this season, making him a reliable option for managers looking for consistency. On the streaming front, options like Ryan Yarbrough and Adrian Houser could also provide value, but with varying degrees of risk associated with their matchups against strong offenses.
