When the Marlins announced that top pitching prospect Jose Fernandez would be promoted to the majors, the result was a 30 percent increase in ownership -- making him the most added player so far. Fernandez went from being owned in 12 percent of leagues to 42 almost overnight.
Also shooting up the most added list are Mariners starting pitcher Brandon Maurer, who will make his MLB debut Thursday, and Red Sox outfielder Jackie Bradley Jr., whose stellar spring landed him in Boston’s opening day lineup batting eighth. Just behind them are Dodgers starting pitcher Hyun-Jin Ryu and Cardinals relief pitcher Mitchell Boggs, rounding out the top five.
