The Nationals are interested in Arizona pitcher Edwin Jackson, according to Jon Heyman of Sports Illustrated (via Twitter). Nats GM Mike Rizzo recently identified starting pitching as the club's biggest need.
A month ago it was reported that Washington was exploring a trade for the righthander, though we haven't heard much else on that front in recent weeks. Rizzo has connections to the D'Backs organization, having served as their scouting director from 2000-2006.
Jackson, who turns 27 in September, has a 5.01 ERA with 7.0 K/9 and 4.0 BB/9 in 20 starts this year. On the whole, he has been unable to replicate his play from last season when he registered a 3.62 ERA with 6.8 K/9 and 2.9 BB/9.
