Carlos Narváez seized Boston’s catcher job in a breakout rookie season, stepping in for Connor Wong after an early IL stint and Teel’s trade to Chicago. He exploded in May, slashing .346/.443/.538 over 32 games, then cooled but remained a defensive cornerstone with 9 outs above average—the best in the AL and among the league leaders. He’s currently .250/.321/.426 with 13 homers, giving the Red Sox a reliable backstop as the team navigates turnover and injuries.
