Mo Pinel

Maurice Louis Pinel Jr, known as Mo, lived from 1942 to March 5, 2021 and was an American mechanical engineer, product designer and bowler. He is known for changing the game of ten-pin bowling with innovative ball designs, notably using asymmetric core masses that let the ball curve more aggressively on its path down the lane. His popular designs, starting in 1991, helped bowlers achieve higher scores and so contributed to the score inflation controversy of the 2000s.
