Zach Duke was rocked for four runs on seven hits over 3 1/3 innings in a loss to the Giants on Monday. Duke struck out one and didn't walk a batter. His most impressive feat of the evening was logging one of the three hits off Giants starter Ryan Vogelsong. Duke, making his first start of the season as a fill-in for Ross Detwiler (lower back), didn't acquit himself well. Though he kept the ball in the strike zone and only allowed one extra-base hit, San Francisco was fooled by none of the offered slop. Duke will presumably now return to the bullpen, though his 8.84 ERA and 1.80 WHIP may not be long for Washington's roster.
