Hammel went 1-3 while posting an ugly 5.83 ERA and allowed six home runs over his five May starts.
Coming off a career-best season with the Cubs, Hammel has been nothing less than a major disappointment through 10 games as a Royal. Among qualified MLB starters this year, Hammel's 6.18 ERA ranks 89th out of 93. The 34-year-old's 4.1 BB/9 and 65 percent strand rate are his worst marks since 2007 with Tampa Bay.
