First-place Michigan State. John Lethemon, the Spartans’ senior goaltender, likes the sound of it. “It feels great. But we have a lot more work to do,” he said. For the second time in seven days, MSU on Friday had an opportunity to climb into first place in the Big Ten. Last Saturday, the Spartans fell short, losing to Minnesota. On Friday, thanks in a big part by the standout play of Lethemon, they won a game that lifted No. 20 Michigan State into the top spot in the Big Ten standings, one point ahead of Penn State.
