I looked at your team and, to be honest, I think you're set to receive a lot more from your players than what you have been getting so far. In other words, barring injury, you should have very little room for regression and plenty of room for progression. Guys like Han-Ram and Heyward seem to be the catalysts for your team's current position.
Great pickup with Sanchez. He's at least an all-around solid starter, but is also a definite candidate for a somewhat-breakout year (one of those "500IP" guys, 27 years old, great park, strong K/9 numbers). You just reminded me that I let him go on my team earlier in the year. I regret that.
I like the idea of moving Santana to your Catcher's slot. Martin is good, and I'd keep him in there for now, but just keep in mind that you could stand to gain a lot by booting him out of your lineup. I'm sure you could find a true 1B that will outproduce Martin, if only because it is such a deep position.
Also, just keep an eye on minor-league guys. I like to build a list of those who are either performing extremely well in the minors or are highly hyped and performing well enough for a promotion. With this list, you could hone in on potential call-ups and gauge whether or not you'd like to take a gamble on somebody. I think it's asinine to think that no fantasy impact players will come up. It has occurred too many times for one to deny himself the opportunity to even consider picking one up. In other words, just be open to these kids, and you could land a Ryan Braun or a guy that, while not nearly as prominent, compliments your particular team perfectly. viewtopic.php?t=431180
