Brock Maxwell’s frustration with his slow start to the 2013 season reached a boiling point Tuesday night. The South Carolina signee was so upset after striking out in his final at-bat of Lambert’s 5-3 loss at North Gwinnett that he drove to the Longhorns’ field after the game and spent two hours by himself hitting off a tee. The extra swings and adjustments Maxwell made seemed to pay off in a big way less than 24 hours later.
