Chicago Cubs' left-hander Justin Steele placed on the 15-day injured list due to a strained left hamstring.

Steele sustained the injury during a game against the Texas Rangers and is projected to miss at least a month.

Cubs manager Craig Counsell does not anticipate Justin Steele pitching again in April.

The Cubs have called up right-hander Ben Brown from Triple-A Iowa to fill Steele's spot in the bullpen.

Ben Brown is set to make his major-league debut after being traded from the Phillies.

Justin Steele was a first-time All-Star and finished fifth in NL Cy Young Award voting last season.
