Jon Heyman of CBS Sports is reporting that Nationals shortstop Ian Desmond turned down a hefty multi-year contract extension over the winter. Heyman’s sources estimate the extension was at least six years in length and between $80 to $90 million in value. The two sides eventually agreed on a two-year, $17.5 million deal in January to avoid arbitration.

Desmond, 28, has become one of the league’s best shortstops. Over the last two seasons, he has hit at least 20 home runs and stolen 20 bases while posting an aggregate .812 OPS.
