Anthony Rendon has turned heads this spring in camp with the Nationals, but there is one small problem. Rendon is a third baseman and Washington just signed Ryan Zimmerman to a contract that could reach $150 million in value. The Nationals drafted Rendon with the sixth overall pick out of Rice last year. "They had to lock him down," Rendon said of Zimmerman. "He's done great for this organization. He's a great player. Why wouldn't you want to lock him down?" For now, Rendon will alternate between third base, shortstop and second base during spring training. Rendon feels comfortable at both second base, where he played last year at Rice upon returning from a shoulder injury, and shortstop, where he played through high school.
