Deception and Unpredictability
The unusual trajectory caused by the low release point adds an element of MLB The Show 25 Stubs deception.

Hitters are used to seeing pitches come from higher arm slots with more “straight” flight paths.

The downward and sweeping action from a submarine delivery breaks this expectation, forcing hitters to adjust their timing and swing path.

4. Inducing Ground Balls
Due to the pronounced downward movement, batters are more likely to hit the top half of the ball, leading to ground balls rather than damaging line drives or home runs.

Ground balls are easier for defenses to convert into outs and reduce the chances of extra-base hits.

Summary
The low release point of submarine pitchers causes pitches to drop sharply and sweep laterally, creating deceptive and difficult-to-hit trajectories. This downward pitch movement is a powerful tool for inducing ground balls and cheap MLB Stubs keeping hitters off balance.
