Rodriguez ranks fifth on baseball's all-time home run list and is closing ground on Hall of Famer Willie Mays (660). Rodriguez's Yankees contract includes a $6 million bonus payable if he ties Mays.
The shot off Dickey was Rodriguez's first since his emotional shot off the Red Sox's Ryan Dempster on Aug. 18, coming innings after Dempster intentionally hit Rodriguez with a 92-mph fastball, earning a five-game suspension.
Rodriguez entered play on Monday in a 3-for-19 (.158) skid in the six games following that contest at Fenway Park.
