AT BATS is a statistic used in baseball to measure the number of times a batter has attempted to hit the ball. It is abbreviated as AB and is calculated by adding hits, walks, hit by pitch, and sacrifice flies. This statistic is important because it gives an indication of how often a batter is able to make contact with the ball. UPS is an abbreviation for Unassisted Putouts, which is a statistic that measures the number of putouts a fielder makes without the help of another fielder.
