The Chicago Cubs say second baseman Javier Baez will take a leave of absence from their Triple-A Iowa affiliate following the death of his sister.

The team says Noely Baez, who was born with spina bifida, died Wednesday night in Florida. She was 21.

Javier Baez is one of the Cubs' top prospects. He made his major league debut last season, batting .169 with nine homers and 95 strikeouts in 52 games. He was optioned to Iowa on March 30.
