Below is a compilation of the Halos' best prospect performances going back to 2005. I give two run values for position players: the "+ bat" is how many more runs that prospect created over their league's average player according to a widely-used runs created formula. The "+ glove" is how many runs that player saved in the field according to Sean Smith's "TotalZone" defensive metric. For pitchers, I compare their runs allowed per game to the league average to generate the "runs saved" metric. Both pitchers and position players are then ranked by "WAR," or "Wins Above Replacement," which is an inclusive metric that incorporates each player's runs values with adjustments for playing time and position. Using the replacement-level concept for minor leaguers brings up all kinds of theoretical sabermetric questions, but I have my reasons for keeping the calculations as similar as I could to those used for major leaguers. Lastly, keep in mind that WAR is a counting stat and minor leaguers play at least 10% fewer games than their major league counterparts, so a 3.9 WAR here is more impressive (for temporal reasons only) than a 3.9 WAR over a 162 game schedule. 30) Anthony Ortega, 2007, High A 7 wins, 11 losses. 163.1 IP, 4.02 ERA, 127 K / 68 BB. +13 runs saved, 3.9 WAR.
