Casto has enjoyed a pair of stints with the Nationals this season and proved to be a steady bat off Manny Acta's bench, going 5-for-18, .278, with two doubles, a homer and five RBI in a pinch-hitting role. His six pinch hits are tied for second among Nationals behind only Aaron Boone. Casto is a two-time Nationals Minor League Player of the Year; 2005, '06.

Gonzalez hit .462, 6-for-13 in four games with the Nationals in early August.

Hinckley, 25, joins the Nationals after posting a 3.16 ERA in 20 International League relief appearances with Columbus. He began the season with Harrisburg and was bestowed the honor of throwing the first pitch in the history of the Washington Nationals in the club's inaugural Spring Training contest on March 2, 2005 vs. the New York Mets. He had entered that season rated as the Nationals' No. 1 prospect according to Baseball America.
