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.

Huston Street notched his 11th save Monday by tossing a perfect ninth as the Padres beat the Cardinals 4-2.
This was Street's first perfect complete inning since May 8 against the Marlins. Street has been uncharacteristically wild this season and that has led to an 0-3 record, 4.19 ERA and 1.24 WHIP (19 points above his career mark). If Street can improve upon his 13/8 K/BB rate (over 20 appearances), he'll have another good season as San Diego's stopper. If he doesn't iron out his control issues, it could be a long year. Street's stuff simply isn't good enough (he's allowed six homers in 2013) to compensate for extra base runners.

Jason Marquis limited the Cardinals to two runs -- one earned -- on three hits over six innings to improve to 6-2 on Monday.
Marquis has won each of his last five trips to the bump and has been one of baseball's best starters over that stretch. We aren't here to pimp Marquis, however, as he's benefited from smoke and mirrors and his home park perhaps more than any pitcher in the game. Marquis' 28 walks lead the National League. And that five-game winning streak? He posted a hideous 17/18 K/BB rate over 31 2/3 innings during that stretch. This house of cards is about to topple and you'd be wise to identify the sucker in your league to pay for Marquis' 6-2 record and 3.27 ERA before it does.
