Saves are the name of the game in lacrosse. A winning team in the NCAA tournament, which culminates Memorial Day weekend, relies on its goalkeeper to come up with acrobatic saves to keep it in the game. For example, University of Maryland freshman Niko Amato keyed a deep run in the 2011 tournament with a 70 percent save percentage, higher than his figures for the season overall. You can calculate goalie save ratios even if your record is less stellar than Amato’s by tracking certain performance metrics.
Record the goalie’s goals allowed and saves for all games during the season.
Add the goals allowed and saves to arrive at a total for all shots the goalie faced. For example, in 2011, Amato played goal in 18 games, allowed 118 goals and made 165 saves, for a total of 283 shots faced.
Divide the saves, in this case 165, by the total shots, 283, to come up with the save ratio, which for Amato is 0.583. The best save ratios for Division I goalies are typically just above 0.500, according to Adam Platzer, author of “Good to Great Goaltending.”
Use a calculator to avoid mathematical errors when calculating goalie save ratios.
While the NCAA website provides an online calculator, if the goalie played less than 60 percent of the team's minutes in goal, the calculator will not provide the desired information.
