Chase Headley became arbitration eligible a year ahead of schedule last winter as a "Super Two."

Because of the designation, Headley's salary jumped from around $500,000 to $2.325 million. Headley's statistics in 2010: .264, 11 home runs, 58 RBI with a .327 on-base percentage.

Headley's numbers this season: .292, four homers, 42 RBI with a .379 on-base percentage. And he's getting better as the season progresses.

Headley's .333 average (49-for-147) since June 13 is the fifth-best in the National League. His .333 road batting average (65-for-195) is also the fifth-best mark in the major leagues.

Headley is also hitting .424 (28-for-66) against left-handed pitchers since May 27 and .469 (23-for-49) since June 17.

In the overall ranking of third basemen, Headley leads all National Leaguers in average, on-base percentage and doubles (28).

Which must give the Padres concerns about what Headley might be valued this winter on the arbitration scale.
