WEEI reports the Red Sox will call up Xander Bogaerts, a consensus top-5 prospect, from Triple-A Pawtucket on Monday.
Bogaerts, 20, will become the youngest Red Sox prospect to make his big league debut since righthander Jeff Suppan in 1995. Dwight Evans also made his Major League Baseball debut at age 20 in 1972.
Bogaerts has hit .297 with 15 home runs, 67 RBIs and an .865 OPS in 116 games for Double A Portland and Triple A Pawtucket this season.
The Boston Globe reports Bogaerts will replace Brock Holt on the 25-man roster and serve as a utility player who can fill in for shortstop Stephen Drew. Bogaerts' natural position is shortstop, but he has also played third base in nine games this season.
The righthanded hitter could also provide a boost for the Red Sox batting order against lefthanded pitchers. Bogaerts was hitting .298 with a .452 OBP, .474 slugging mark, 16 walks and just seven strikeouts in 73 plate appearances against lefties.
