How Federer DISGUISED His Slice Serve! (Slice VS Flat Comparison)

Federer’s Slice Serve

The video analyzes how Roger Federer disguises his slice serve and compares it with a flat serve. No timestamps are provided, so the key moments are described in sequence.

Federer begins in a platform stance, slightly angled toward the net post, with a relaxed hitting arm and the racket held unusually far back. As he tosses the ball above shoulder level, he turns his shoulders deeply and loads his legs. In the trophy position, he keeps the racket edge difficult to read. As he drives upward, the racket drops behind his back.

For the slice, Federer leads toward contact with the racket edge. He lets the ball fall slightly, then brushes across its outer side, with the strings angled roughly 45 degrees. His palm does not fully rotate forward at impact. He extends upward and follows through across his body, sending the serve wide.

Comparing Serve Directions

The presenter compares an open-court serve with a serve down the T, pausing both just before contact. Their tosses and preparations look remarkably similar.

Only very late does Federer adjust the racket and pronation: pronation comes later on the open-court serve and earlier on the T serve. The T serve becomes a clean ace. The comparison illustrates why the presenter considers Federer’s serve exceptionally difficult to read, even in slow motion.
