Gary Sanchez is off to one of the best starts in Yankees history.

The rookie catcher has hit nine home runs since being called up to the majors on Aug. 3, including two multi-homer games and an upper-deck shot against the Mariners on Wednesday.

Sanchez was named AL Player of the Week for the period ending Aug. 21 after going 11-for-21 (.524) with four homers, six RBIs, two doubles, four runs and a steal. He became the second Yankees catcher to ever win the award — Thurman Munson won it on July 25, 1976.
