OAKLAND, California — For only the third time this season, the Rockies failed to win a game that Chad Bettis started.
The way Colorado scored in this three-game series against the Athletics, it probably wouldn't have mattered much who was on the mound.
Bettis pitched into the sixth inning but the Rockies got little going offensively in a 4-1 loss to Oakland on Wednesday.
"Chad hung in there, it was a start I feel like he could have won," manager Walt Weiss said. "We had some opportunities early and we didn't execute. Could have got out to an early lead. We just didn't execute very well on offense."
Colorado led the National League in scoring during June but managed just four runs in while dropping two of three to Oakland.
The Rockies also fell to 0-12 when getting one run or fewer.
Even Nolan Arenado struggled, going 0 for 4 to end his 17-game hitting streak.
"Just a tough road trip, especially here in Oakland," said Colorado slugger Carlos Gonzalez. "We didn't score a lot of runs this series. We know that the offense needs to get going."
Billy Butler hit his first triple in nearly three years and also singled, Jesse Hahn (6-6) improved to 4-1 over his last six starts after giving up one run on four hits. He walked two and struck out six.
Tyler Clippard retired the final four batters for his 14th save.
In his 10th start, Bettis (4-3) allowed three runs on seven hits and four walks in 5 2-3 innings.
"I feel like my stuff was flattening on in the middle innings," Bettis said. "You don't have sink or depth on your pitches, they get hit."
Butler led off the third with a shot into left field. Rafael Ynoa slammed into the wall and was shaken up, allowing Butler to chug into third, his first three-bagger since August 2012.
Butler scored on Sogard's sacrifice fly, and hit an RBI single in the fifth. Burns tripled leading off third and scored on Reddick's double.
Rockies: SS Troy Tulowitzki was given a routine day off because of the quick turnaround from Tuesday night. Weiss never thought about using him as a DH. "I brought it up to him in Houston and he didn't like it," Weiss said. "I didn't bother him this time."
Athletics: Ace Sonny Gray spent the night in a hospital with severe gastritis, a stomach ailment that kept him from making the start Tuesday night. "This wasn't a minor thing," manager Bob Melvin said. "We wanted to make sure he was hydrated." Melvin is unsure if Gray will be ready for his next on Sunday. Chris Bassitt will start if Gray can't go.
Rockies: LHP Chris Rusin (3-2, 4.69) makes the start in Thursday night's series opener at Arizona. He'll be facing the Diamondbacks for the first time in two years. He's 2-0 with a 2.70 ERA against them in two previous starts.
Athletics: LHP Scott Kazmir (4-5, 2.79) starts against the visiting Seattle Mariners on Thursday night. He's 2-2 with a 2.31 ERA over his past six starts and 4-0 with a 1.09 ERA in six starts against the AL West.
