The Boston Red Sox have made the decision to start top prospect Marcelo Mayer as their new second baseman for the upcoming season. This move is part of a larger strategic shift for the team, which also involves the future of infielder Kristian Campbell. The article analyzes the implications of these decisions and how they fit into the Red Sox's long-term plans.

Why it matters

Mayer's transition to second base is a calculated risk by the Red Sox, as they look to capitalize on his defensive skills while protecting his bat against left-handed pitchers. Meanwhile, the decision to option Campbell to Triple-A raises questions about the team's roster management and player development strategies.

The details

Mayer, once a top Red Sox prospect, is now stepping into a crucial role at second base. Despite a lukewarm Grapefruit League performance, the Red Sox see potential in Mayer and believe his defensive abilities can be a game-changer. This move is part of a larger plan that includes the acquisition of Caleb Durbin for third base, clearing a path for Mayer. As for Campbell, the former rookie sensation struggled in his first full season, prompting the Red Sox to option him to Triple-A. This decision suggests the team is carefully balancing Campbell's development with their crowded roster.

  • Mayer's performance in the Grapefruit League was the basis for the Red Sox's decision to start him at second base for the upcoming season.
  • Just a year ago, Kristian Campbell earned a spot on the Red Sox's Opening Day roster and a substantial contract extension.
