Contreras went 2-for-4 with a double in Saturday's 3-2 loss to the Giants.
After sitting out the previous two games in favor of veteran David Ross, Contreras was productive upon his return. The 24-year-old has a four-game hitting streak and has hit safely in six of his last seven overall. He's put together a solid rookie season as part of a platoon, slashing .274/.349/.466 over 208 at-bats.
