Marlins prospect Mesa diagnosed with strained hamstring

JUPITER, Fla. (AP) — Miami Marlins outfield prospect Víctor Víctor Mesa has been diagnosed with a grade one right hamstring strain and reassigned to minor league rehabilitation, a setback in the development of the highly regarded Cuban defector.

Mesa underwent an MRI after being hurt Sunday in a spring training game against the Pittsburgh Pirates. He had been expected to play a lot for the Marlins in spring training before heading to the minor leagues to start the season.

Mesa was rated baseball’s top international prospect when the Marlins signed him for a $5.25 million bonus last October. Going into spring training, he had not played in a game in nearly two years.
