VORP stands for Value Over Replacement Player. This is a mark of offensive value over the idea of a replacement player, basically a player thats somewhere about 70% below the average for a position. The idea is a replacement player is the typical AAA veteran who's 27-32 years old and can be had for league minimum. VORP tells you how many runs better (or worse) a given player is than a replacement player at that position. Its calculated by BP and since they went more pay, not really paid as much attention to because its hard to get at. FIP stands for Fielding Independent Pitching, Its based on the idea that a pitcher has little control over what happens when a hitter puts a ball in play. The pitcher mostly controls the K rate, BB rate, and HR rate. FIP tells what a pitcher's ERA would look like if the BABIP behind them were at league average.
