With just over a minute to go in the fourth quarter against Mundy’s Mill Monday night, Eastside freshman basketball player Isaiah Miller got an introduction to what it takes to compete at the varsity level. Leading 63-60 over the Tigers, the 5-foot-9 Miller grabbed a rebound, took the ball coast-to-coast, and gently laid the ball up off the glass as a foul was whistled on his defender. Miller knocked down the ensuing free throw, preserving the Eagles’ late lead for a 68-65 victory over Mundy’s Mill in Eastside’s first game of the 2013 Walnut Grove High School Thanksgiving Shootout.
