Nick Punto was hitless in four at-bats and struck out twice from the leadoff spot in Saturday's loss to the Orioles. Red Sox manager Bobby Valentine hit Punto leadoff once last month, and that worked out well. This time, not so much. The scrappy infielder is now batting just .148 in 27 at-bats and has tallied just one extra-base hit. His last base knock came on April 10.
