The Mets' R.A. Dickey has become the first knuckleballer to win 20 games in more than three decades. 
In New York's last game at Citi Field, Dickey also had a career-high 13 strikeouts, prompting a standing ovation from the crowd of about 30,000 in the eighth inning. 
The last team member to earn 20 wins was Frank Viola.
