Roush demonstrates his classic slap hitter style, he was perhaps the preeminent place hitter of his generation. This photo shows him with the Newark Peppers of the Federal Leaugue in 1915.

Here is a paragraph from SABR’s bio on Roush:

“Roush wielded a short, thick-handled bat that weighed 48 ounces, one of the heaviest ever in baseball. He snapped the bat at the ball with his arms and placed line drives to all parts of the field by shifting his feet after the ball left the pitchers hand and altering the timing of his swing. “Place hitting is in a sense glorified bunting,” he said. “I only take a half swing at the ball, and the weight of the bat rather than my swing is what drives it.”

The photo perfectly exhibits the technique described above.
