Baseball America posted an extra set of scouting reports, and Lancaster/Tri-City pitcher David Duncan is included:
Duncan began 2009, his first full pro season, at high Class A Lancaster, one of the worst pitcher's parks in the minors. He went 0-9, 8.51 in two months, with his difficulties compounded by the fact that the Astros wouldn't let him use his 82-84 mph splitter. It's his best pitch, but he tended to rely on it too much. Duncan found more success after a demotion to low Class A Lexington, where Houston let him use his splitter again. The rest of his repertoire is below-average. A tall, lanky lefthander throwing from a high three-quarters arm slot, Duncan also has an 86-89 mph fastball and a slow, loopy curveball. Though he doesn't miss many bats, he does do a good job of keeping the ball on the ground. Some scouts think he profiles better as a reliever than as a starter. He'll return to Lancaster in 2010.
