wOBA: "wOBA or weighted on base average is a statistic developed by and used with the permission of Tom Tango. In a nutshell, wOBA uses linear weights on certain batting events to come up with a metric that is more statistically sound than OPS and is scaled onto an OBP scale. According to Tango "An average hitter is around 0.340 or so, a great hitter is 0.400 or higher, and a poor hitter would be under 0.300." This is how well they hit.
bRAA: "Stands for batting runs above average. It is computed by taking the hitter's RV/PA (Run value per PA above average = (wOBA for player - wOBA for league) / 1.15.) and multiplying by the number of plate appearances he has had that season." This is how much 'value' they added (or cost) their team based on the quality and quantity of their hitting.
