Although Trumbo ranks ninth in the AL with 19 home runs, nine of those went at least 425 feet, the most in baseball. His average home run distance is 417.7 feet, fourth in the majors (minimum 10 home runs), and all but three of his home runs would have been out of Citi Field.
Cruz has 22 home runs this season, including ones that went 450 feet and 445 feet. Nineteen of those homers would have been out of Citi Field.
Although Cruz's average home run distance is 410.4 feet (12th among players with at least 10 home runs), his average home run distance is 419 feet when excluding his opposite-field home runs.
Other AL options:
Miguel Cabrera, Detroit Tigers: It is hard to keep Cabrera off this list, as he is second in baseball with 27 home runs. However, his average home run distance is "only" 406.7 feet, 25th in the majors (minimum 10 home runs).
Raul Ibanez, Seattle Mariners: Ibanez has 21 home runs, but his average home run distance is 383.6 feet, the lowest in the AL (among those with at least 10 home runs). Only four of those 21 were longer than 400 feet, and nine would not have been homers at Citi Field.
Adam Dunn, Chicago White Sox: Despite having 23 home runs, including six of at least 430 feet, Dunn ranks 17th in average home run distance.
Mike Trout, Los Angeles Angels of Anaheim: Trout has the third-highest average home run distance in baseball (419.5 feet), but his 14 home runs were not enough to make the top three.
