Certainly the lack of walks from Estrada hurt his value, but just as disconcerting were his lack of RBI's and clutch hits. Really, his lack of RBI's and clutch hits worry you? He hit better with runners on base than the bases empty, though a little worse when they were in scoring position. He did have two grand slams as well, right? He was great the year before with RISP. Its just small sample fluctuation. For his career he hits 20 points better with RISP, and OPS over 100 points better! So its a little dissapointing, but I have zero concern over that going foward. I want to see the walks.
