Yes, if a player chooses to leave a Walk or Extra Walk card face-down in the "Highlight of the Day" position, they receive the two points printed at the bottom of the card instead of the standard one point for a face-down Walk.

This is supported by the following rulebook references:

• On page 10:

  "If a Walk or Extra Walk card was placed at the bottom of a column in the 'Highlight of the Day' position and the player chooses to leave it face-down, then that card scores an additional 2 points, as indicated at the bottom of the card, with no requirements that need to be fulfilled."

• On page 7:

  "If left face-down, the card is worth 2 points, as indicated at the bottom of the card."

This means:

• The standard one point for a face-down Walk is replaced by the two points shown at the bottom of the card when it is in the "Highlight of the Day" position and left face-down.
• The player does not receive both the standard one point and the two points; they receive only the two points as specified for the Highlight of the Day position.
