The seven-year extension the Washington Nationals gave Stephen Strasburg on Monday night could lead to a heightened trade market, writes Jon Paul Morosi.

"Strasburg's sudden absence from the upcoming free-agent class effectively removes the possibility of any Major League Baseball franchise signing a No. 1 starter and perhaps even a solid No. 2. Japanese right-hander Shohei Otani -- the Yu Darvish-like ace of the Hokkaido Nippon-Ham Fighters -- is unlikely to be posted this winter, and the domestic free-agent pool is devoid of top-end talent," Morosi writes.

Bartolo Colon, Rich Hill, Juan Nicasio, R.A Dickey and Mat Latos will be the most productive starters on the market this winter, which could motivate teams to make a trade for a top-level starter.
