Molina is having an impressive year offensively. He was hitless in three at-bats during a 2-1 win on Saturday but finished the day hitting .303. Molina finished the day with career highs in home runs (13) and RBIs (63). He led all National League catchers with 11 three-hit games.
La Russa pointed out that sometimes Molina's defensive abilities overshadow his hitting skills.
Molina has won the Gold Glove Award each of the past three seasons.
"I'm not sure enough people are paying attention," La Russa said.
Atlanta catcher Brian McCann and Arizona catcher Miguel Montero are among the other leading candidates for the NL Silver Slugger.
