"The Marlins shelled out $7?million — a big chunk of change for the thrift-conscious franchise — to sign Javier Vazquez. They're not getting their money's worth. Not even close.

For the fifth time in his 13 starts this season, Vazquez failed to reach the fifth inning as the veteran pitcher was rocked again in a 9-5 loss to the Diamondbacks on Saturday night.

The pitcher's earned-run average of 7.09 is the worst in the majors among regular starters and more than a run higher than the next-closest pitcher.

"Nothing's going right," Vazquez said. "I wish I could explain it."

The Diamondbacks erupted for six runs in the fourth, sending Vazquez to the showers before he could finish the inning and sending the Marlins to their 11th loss in their past 13 games.

Because the Marlins don't have any ready options waiting in the minors, Vazquez's spot in the rotation appears to be safe, at least for now. But the Marlins might not wait much longer to pull the plug on the 34-year-old if the poor outings continue.

Vazquez has allowed six runs or more in six of his 13 starts. Opposing batters are hitting .297 against him. He has given up 11?home runs, including two Saturday."
