Headley, who hit only four home runs last season, had two home runs in the first eight games this season. He hasn't sacrificed his discerning eye for the power, as he's ranked among the NL leaders in walks early in the season.
Headley has never appeared in a Midsummer Classic. Of the eight Padres on the ballot, only Hudson, Bartlett and Quentin have been in an All-Star Game.
Quentin, who is on the disabled list after having knee surgery in March, was 0-for-2 as a representative of the White Sox in the 2011 All-Star Game at Chase Field in Phoenix. Quentin is expected to rejoin the Padres in early May.
