Johan is doubly good

Johan Santana just hit his fourth double of the year. Here's a little tidbit pointed out by my good friend Ryan P. on Mets Lounge:

Santana has tied the amount of doubles with Luis Castillo.

Santana has 4 doubles in 22 ABs.
Luis Castillo has 4 doubles in 143 ABs.

Santana also has more doubles than Moises Alou (43 ABs).

That's a good sign.
