Tangerine Mint Spritzer

Cut the tangerines in half. Peel and segment one half of a tangerine and place in an 8 ounce cup. Add the mint and agave and muddle (crush) in the bottom of the glass. Squeeze the tangerine juice from a whole tangerine into the glass and add ice cubes and optional rum. Top off the glass with club soda. Cut the remaining tangerine half into slices for garnish.
