Softball fans know when Sierra Romero steps up to the plate, they have an opportunity to catch a legendary "Rom-bomb".  A true threat at the plate, Romero proved during her freshman campaign at the University of Michigan she was a force to be reckoned with.  In her first season, she earned Big 10 Freshman of the Year AND Big 10 Player of the Year while establishing a single-season UM record with 23 home runs.
