In 2009, when he was ahead 0-2 or 1-2 on a righty, he threw his fastball only 25 percent of the time. "In 2010, he upped that rate to 35 percent, then upped it again to 47 percent last season." - ESPN.com's Mark Simon and Lee Singer on changes new Nats' lefty Gio Gonzalez has made in the last two seasons.
