BOSTON -- The Marlins could begin the second half of the season a healthier ballclub, as third baseman Martin Prado began a rehab assignment on Tuesday night, and right-hander Henderson Alvarez is on track to start one of his own next week.
Prado, placed on the 15-day disabled list last month with a right shoulder sprain, served as the designated hitter for Class A Advanced Jupiter. He spent the last few weeks participating in a muscle strengthening program aimed at helping his recovery.
