Santana is throwing off flat ground and hopes to get back on a mound later in April, Ken Fidlin of the Toronto Sun reports. The 35-year-old hasn't pitched since 2012 and hasn't pitched more than 25 starts since 2010. The former Cy Young winner still has a long road ahead of him, but because he's still on the same track laid out late in March. Santana needs to demonstrate that he's not only healthy, but also effective before he's really worth consideration in fantasy leagues.
