Roberts carrying big stick

The best part of monitoring baseball's statistical leaderboard in April is wondering which players will still be around come July or August.

Ichiro Suzuki might not hit .404 all year, but history says he'll challenge for the American League batting title. And while it's hard to envision Miguel Tejada maintaining a 224-RBI pace, the guy did knock in 150 runs a year ago.

For every familiar name, there's an unexpected intruder who might or might not have legs. When Brian Roberts leads the AL in slugging or Gustavo Chacin is tied with Johan Santana for the most wins, you have to wonder whether they're destined for breakthrough seasons or just blips on the statistical radar screen.
