Mike Rizzo said earlier this winter that if he was asked about any of the Washington Nationals' pitchers participating in the World Baseball Classic he would make a decision on whether or not they participate on a case-by-case basis. Coming off his best season at the major league level, which saw 26-year-old, Nats' '07 1st Round pick Ross Detwiler go (10-8) with a 3.40 ERA, 4.04 FIP, 52 walks (2.85 BB/9) and 105 Ks (5.75 K/9) in a +1.8 fWAR campaign, the Nationals' 6'5'', 190 lb left-hander today accepted an invitation to pitch for the United States in next month's World Baseball Classic. Detwiler becomes the third player from the Nats' major league roster to agree to participate in the international tournament which starts, for Team USA, on Friday March 8th, joining Gio Gonzalez on the US roster and Curacao-born outfielder Roger Bernadina, who will play for the Netherlands.
