A former Yankees manager has some suggestions for how the new manager can help fix Gary Sanchez's defensive issues.

Joe Girardi went 910-710 in charge of the Yankees from 2008-17 while leading the Yankees to Game 7 of the ALCS last season before being replaced by Aaron Boone. He has some suggestions for his successor. A former MLB catcher himself, Girardi went on MLB Network's "High Heat" to dissect Sanchez's shortcomings.

"Over the next four weeks, I'd try to fix his base," Girardi said Thursday on MLB network's "High Heat" with Chris "Mad Dog" Russo. "It's his base, the left knee collapses and he's not in a position to catch some of these balls and block some of these balls."

Sanchez is tied for a league-worst 13 passed balls this season despite having missed time due to multiple DL stints. Last season, he had the most passed balls in the AL with 16 in 122 games.

On top of his well publicized tribulations behind the plate, the 25-year-old has struggled with in the batter's box as well. This season he's hitting .186/.283/.411 with 15 HR and 45 RBI.

Sanchez will hope to right the ship before the playoffs as the Yankees look to lockdown a home wild-card game.
