Uh, no. Most players don't see their power numbers go up at age 35. Most players decline as they age. Just look how the powers numbers shot up. And the 73 just comes out of nowhere.
Innocent until proven guilty... fine, but I have my opinions and it just looks suspicious. I don't like the guy and I won't root for the guy because I think he's a cheater (along with McGwire and Palmeirio and Sosa, etc.).
