Santana has got some nasty stuff that you don't often see in such a young pitcher. It's not fair to say that "every" prospect has his level of talent. They clearly don't. So far, he's been either dominant or got shelled. The dominance is intriguing because -- again -- very few hot prospects are able to dominate at all within the first few major league games they played. Most struggle for a LONG time before they finally put it together (if ever).
I'm not too concerned about the shelling by Texas. EVERY pitcher they threw into the game got shelled. Texas has a blistering line-up and every one of them were on their game that day. When that happens, I don't care who is on the mound -- prime RJ, prime Pedro, prime Gagne, whatever -- they're gonna get hit hard.
I'll give Santana a few more games to get it together. If he does, he'll be a solid fantasy option that I picked up for free off the FA list. If he doesn't, he'll just be another in a long line of starters that didn't pan out this year.
I am the Master. Don't question the Master. Just do what he says and be proud.
