The Jason Grimsley saga is about to get very interesting. We know that Grimsley named names – people who he knew to be using and distributing steroids, amphetamines, and human growth hormone – and now we have our first clues as to who those people are, thanks in large part to the folks at the Smoking Gun and Deadspin.com. How do we know? IRS documents say that Grimsley says a former fitness trainer referred him to an amphetamine source and that this source later became his source for steroids and HGH.

Deadspin says the “former fitness trainer” is a guy named Chris Mihlfeld, who used to work for the Kansas City Royals. Grimsley mentions Mihlfeld in a first-person narrative that he wrote for MLB.com. In that article, Grimsley tells how a twin-engine plane crashed into his house and changed his outlook on his recovery from Tommy John surgery:

That new outlook had a positive effect on the rehabilitation process. It relaxed me. It made me realize that anything that happens from here on in my baseball career is a bonus. I knew I’d been given another chance. So I told my doctor, Timothy Kremchek, and my trainer, Chris Mihlfeld, that my arm felt good and I wanted to step on the gas. I told them, “I want to push it and see if my arm will break. I’m not afraid because I don’t have anything to lose.

Here’s where it gets really, REALLY interesting. Mihlfeld is also the trainer for…wait for it…Albert Pujols. Here’s a blurb from a story in the Kansas City-based Capital Journal about how Pujols went from a 13^th round selection to a baseball GOD:

There were other concerns about [Pujols’] defensive ability and where Pujols would fit on a Major League team.

Consequently, a frustrated Albert Pujols — after spending a year at Kansas City’s Maple Woods Community College, where he met strength and conditioning guru Chris Mihlfeld and started the process of building an Adonis-like upper body– waited 13 rounds before getting the call from the Cardinals.

How long will it be before we see Pujols in front of a grand jury? Stay tuned.

Jason Grimsley has been busted for taking human growth hormone, steroids and an innopropriate amount of Sunny Delight. That in and of itself isn’t a big deal. Just add him to the list of small-time players who have failed drug tests. But here’s a line from the ESPN.com story on Grimsley that really got my attention:

According to [IRS agent Jeff] Novitsky, Grimsley told him the names of other players he believed were using, but the names of those players were blacked out of the court records.

Jason’s been talking. How long will it be before the IRS or FBI starts banging on players’ doors with search warrants? It’s been amazing how, up to this point, there haven’t been more players cooperating with the feds, squeeling on other guys in order to keep their asses out of jail. But apparently the good-old-boy system is breaking down.
