Mazara is expected to be called up from Triple-A Round Rock after he was pulled from Saturday's game against Triple-A Iowa following the news that Shin-Soo Choo suffered a right calf strain, SB Nation's Adam J. Morris reports.

Mazara is one of the top fantasy prospects in baseball, as he has an elite hit tool and the potential to offer 30-plus home runs in his peak years. The fact that the Rangers appear willing to add Mazara to the 40-man roster suggests that if he can hit the ground running, he could be a big part of the Texas offense this season. Again, nothing is official, but the time to scoop Mazara up is now, as the demand will be through the roof once a move is confirmed.
