ST. LOUIS - It had been nearly a year since Trevor Cahill had such a rough night.

Cahill was hit hard over five innings and the Arizona Diamondbacks lost 7-1 to the St. Louis Cardinals on Monday.

"I was just falling behind a lot," he said. "I was just behind in the count it felt like the whole game and the couple times I was ahead I wasn't able to put them away. If I'm working behind in the count they're too good of a team to have a good game when you're 1-0 or 2-0 the whole time."

Cahill (3-6) was charged with five runs and nine hits in five innings. He walked three and had no strikeouts for the first time this season. He had allowed four earned runs or less in 29 consecutive starts dating to June 27.

"You've got to execute a certain way because everyone knows they're a very good hitting ballclub especially with runners in scoring position," Arizona manager Kirk Gibson said. "He really didn't have very good command. His ball to strike ratio wasn't good. Give those guys some credit. You've got to execute better, keep the ball down and we weren't able to do that tonight."

Cahill threw 53 of his 91 pitches for strikes while falling to 0-2 with a 6.75 ERA in two starts this season against the Cardinals.

Lance Lynn pitched seven solid innings for major league-leading St. Louis (38-19), which got home runs from Yadier Molina and Carlos Beltran.

The Cardinals went 4 for 8 with runners in scoring position against the usually stout Cahill. Entering the game, batters had just a .111 average against him in that situation.

Lynn (8-1) allowed one run and five hits, struck out six and walked one. He improved to 8-1 for the second consecutive season while becoming the third National League pitcher to reach eight wins, trailing Patrick Corbin's league-leading nine for Arizona.

"It was a good night," Lynn said. "We had a good plan and I was able to make some pitches."

Molina hit a leadoff drive in the fifth on the same day he received a one-game suspension from Major League Baseball for making contact with umpire Mike Everitt during an argument on Sunday. The All-Star catcher appealed the decision.

Molina's fourth homer lifted St. Louis to a 5-0 lead. He finished with two hits and two RBIs.

The D-backs got their only run in the sixth. Gerardo Parra had a leadoff double, moved up on Martin Prado's flyout and came home on Paul Goldschmidt's groundout.

It was the only time Arizona got past first base against Lynn.

"He's very deceptive," Gibson. "He's pitched well for them this year and he pitched a good game against us tonight."
