What is the "lag" you speak of? The minor league pitcher hasn't been called up yet.
As for the guy whining about Felix last year...Yahoo was all over Felix and added him a day or 2 before he actually made his first start. He cleared waivers the day after he pitched.
It's true they are sluggish sometimes but let's not get too carried away. Not every fantasy owner can sit by the computer watching Rotowire and reading minor league call up notes, pressing F5 repeatedly for hours a night to refresh their browser, just to pounce on newbie MinorLeaguer_023 the instant there's a rumor that the kid might, possibly, at some date in the future, get the call up. If it takes a couple days...then it takes a couple days.
