The Cubs will start Javier Baez at second base on either Monday or Tuesday, according to Cubs manager Rick Renteria. The report comes from Gordon Wittenmyer of the Chicago Sun-Times.

Baez, rated the fourth overall best prospect by Baseball Prospectus, has played exclusively at shortstop throughout his three-year professional career. As Wittenmyer notes, it would be Baez’s first start at second base since high school. With Starlin Castro already at shortstop, the Cubs have comparatively more flexibility at second base with Darwin Barney.
