Cubs promote Kris Bryant

The Chicago Cubs have promoted 2013 first-round pick Kris Bryant to Triple-A Iowa.

Bryant tweeted about the promotion Wednesday, and the team later confirmed it.

Bryant, 22, led the Southern League at Double-A Tennessee in batting average (.355), home runs (22), RBIs (58), on-base percentage (.458) and slugging (.702).

Previously, the Cubs said their top prospects have to dominate each level in the minors before being promoted.

Bryant, a third baseman, has been on a tear since winning honors as best collegiate player last season at the University of San Diego.

The Cubs chose him No. 2 overall in last June's amateur draft, and he quickly took to the professional game. Bryant hit .336 with nine home runs last season in Single-A. He went on to win Arizona Fall League MVP, and now leads the Southern League in all three Triple Crown categories at the All-Star break.

On Monday, Bryant won the Home Run Derby at the Southern League All-Star Game.

He joins another top pick, Javier Baez, at Iowa. In addition, Manny Ramirez is headed there shortly as a coach and a part-time player.

Headed to Triple-A along with Bryant are right-handed pitchers Arodys Vizcaino and Armando Rivero.

Vizcaino, 23, is still a highly regarded prospect despite two years of arm problems. The Cubs purposefully started his season in the warm weather of Class-A Daytona then moved him up to Double-A Tennessee. He had a combined 1.99 ERA at both stops in 23 games. Rivero, 26, had a 1.59 ERA at Double-A appearing in 26 games. Both performed well for Cubs brass in spring training.
