The Padres losing streak attained another millstone Monday night at Petco Park.

Behind the pitching of Tyler Chatwood and an offense that took advantage of Edinson Volquez’s erratic offerings, the Colorado Rockies put their own recent problems aside to defeat the Padres 4-2 before a turnout of 20,400.

The loss was the Padres 10th straight.

Remember that number – 10.

Not only do 10 straight losses match the third-longest losing streak in franchise history, Monday night’s loss dropped the Padres to 10 games under .500 – equaling their low-water mark of the season.

Once before, the Padres were 10 games under .500 at 5-15.

It took them 48 games to get back to .500 for the first time at 34-34. It took them exactly 10 games to fall back to 10 under.

A Padres team that was within two games of the National League West lead on June 18 is now closer to having the worst record in the league than to the leaders of their division.

“This is not where we want to be,” third baseman Chase Headley said Monday afternoon while discussing the Padres roller-coaster season.

“Everyone has been disappointed at the way we have been playing. But there’s no panic. Overall, we’re still positive. Over the course of the season there are going to be stretches where you play bad.”

This is as bad as the Padres have played over the course of many seasons.
