Wang signed a one-year, $1 million contract heavy on incentive this December, and the report detailed many of them. Wang joined the Nationals’ active roster on July 29, and he has already earned $250,00 for remaining on the roster for 30 days.

He will earn another $500,000 for staying on the roster for 60 days, a mark that would come Sept. 27, the day before the final day of the regular season. One assumes this is not a coincidence, and would be another reason for Wang to feel good will toward the Nationals when deciding on which team to sign with in the offseason.

Wang will also earn an extra $100,000 for every start he makes once he hits his 10th start. If Wang starts every fifth game until the end of the year, he would make 12 starts total, giving him another $300,000.

Wang also earned an unspecified roster bonus for simply joining the roster for his first start, a source told the Post in July.

The Nationals originally signed Wang to a one-year, $2 million deal in February 2010, as Wang was more than six months removed from major surgery to repair a torn capsule in his right shoulder. Wang did not throw a pitch all season. The Nationals non-tendered Wang, then signed him to his current deal in December.

After more setbacks, Wang finally made his return this summer, more than two years after he made his final start for the New York Yankees on July 4, 2009.

Having fallen into a pattern of starting slow and finishing strong, Wang is 2-3 with a 4.43 ERA. He has struck out 12 and walked 13 in 44 2/3 innings, throwing at least 5 2/3 innings in his last six starts.
