Lucas Harrell threw four innings of no-hit ball in the Astros 4-2 win over the Nationals Saturday. Harrell, 27, was scratched from his last start with a groin injury but was stellar in his return, surrendering just two walks in his four innings. The righty was a pleasant surprise in 2012, registering a 3.76 ERA in 193 2/3 innings. The switch to the AL and the fact that the Astros likely won't win 70 games makes him a risky proposition in mixed leagues, but he's rosterable in AL-only formats.
