The Chicago Cubs will call up prized infield prospect Javier Baez, who will make his major league debut on Tuesday against the Colorado Rockies. The Cubs' first-round pick in 2011, Baez, ranked by ESPN.com's Keith Law as the eighth-best prospect in baseball, has recovered from a slow start in his first season at Triple-A Iowa. After batting just .172 in April, Baez has trended up each month since. In the 20 games following the Triple-A All-Star break, he hit .342 with nine homers and a 1.159 OPS. He batted .300 with 10 home runs in July and hit his 22nd and 23 home runs on Sunday. For the season, the 21-year-old Baez is slashing .260/.323/.510 with 80 RBIs.
