The state high school baseball tournament is underway in Marshalltown and Carroll. An upset opened the 2A quarterfinals in Marshalltown. South O’Brien pitcher Clark Egdorf helped his own cause with a two out single to center that scored the eventual game winner as the Wolverines edged top-seeded Cascade 2-1. Egdorf limited Cascade to just three hits but did not feel like he had his best stuff. He says he felt better at substate.South O’Brien improves to 19-13 and Egdorf says the Wolverines have found ways to win the close games. Cascade led 1-0 in the top of the sixth but two Cougar throwing errors on the same play with two outs allowed pinch runner Andrew Dau to score and tie the game at one.
