"Madden has shown signs of being able to handle more innings," Harvard Coach Joe Walsh said last week. "I think you'll see him making a lot more starts this year."
Madden battled, allowing seven hits but only two earned runs over three innings before giving way to Duffell.
But Duffell displayed the form that has made him a consistent threat throughout his career and showed none of the ill effects of surgery that limited his strength at times last season.
"I just treated it like another start," Duffell said. "I threw well and had some great defense played behind me and my arm felt 100 percent."
Harvard tagged Clark (0-1) for five runs in the first three innings, with Woodfork providing the big blow on a two-run double in the second. Sophomore rightfielder Scott Carmack, whom Walsh said made excellent off-season progress, went 3-for-3 with an RBI and two runs scored in the romp, while sophomore leftfielder Joe Llanes, who made the jump from the JV program, was 2-for-2 with an RBI and a run scored.
Walsh also switched captain Hal Carey from third base to shortstop in the fourth game. Carey spent about half of last season at second base before swapping with Woodfork.
