Red Sox are promoting 2B/3B Anthony Seigler from Triple-A Worcester, according to Tommy Cassell, who covers the Triple-A team.
Seigler was the third person who came to the Red Sox in the Kyle Harrison trade, along with Caleb Durbin and Andruw Monasterio. Seigler is hitting .298 with three home runs and 21 RBI in 104 at-bats for Triple-A Worcester this season but hit .344 in May. He makes a ton of contact and has some experience as a catcher but has only played second and third base this season, so it remains to be seen what his role will be in Boston.
