It's the start of spring training in baseball, which means all 30 general managers can agree on one thing: They all had a successful winter. But which team improved itself the most?
The answer won't be known for months, but we can make an educated projection. The Wall Street Journal examined every off-season transaction and ranked each team based on how many projected marginal wins it added or lost.
he calculations were based on each player's projected wins above replacement (WAR), a statistic used to compare a player's value to the average Triple-A fill-in. The forecasts were made by Dan Szymborski, a sabermetric analyst whose projection system, Zips, is considered among the most reliable. It uses weighted averages of four years of data and adjusts for age based on aging trends of similar players. The rankings don't include contract extensions or promotions within organizations.
