Reds manager Jerry Narron didn't think that was the issue.
"He was not locating where he wanted to, for whatever reason," Narron said. "[Hume and Tunnell] spent a lot of time looking to see if he was doing anything last night that gave away pitches.
"They kept seeing the same thing all of us saw last night. The pitches were right there to hit."
In his last seven starts, Ramirez had allowed 30 earned runs over 35 innings (7.46 ERA). He is 4-8 with a 4.93 ERA in 19 games, including 18 starts, this season.
Although the Reds acquired a former starter in Ryan Franklin from the Phillies on Monday, there were no plans to take Ramirez, 23, out of the rotation for now. He is still scheduled to start on Saturday at Philadelphia.
"He's a couple starts away from striking out seven straight guys [at Houston on July 27]," Narron said. "It's all about location."
Mired in a nine-game winless streak and stuck on victory No. 9 since June 19, Reds starter Bronson Arroyo has pulled out all the stops.
On Tuesday, Arroyo's long blond hair was put into cornrows, channeling a look he had in 2004 with the Red Sox.
"I'm just trying to channel my 10th win," Arroyo said. "I didn't lose for a long, long time [in 2004] and I left them all the way through the World Series."
ESPN's "Cold Pizza" program even carried the transformation live from the right-hander's house.
With Boston, the cornrows look came out of a running joke with former teammate Derek Lowe and physical therapist Chris Correnti.
"Every win, whatever number it was, [Correnti] would have a name for it," Arroyo said. "If it was the third win, he might say 'We're looking for Babe Ruth this week.' And No. 10 was, 'We're looking for Bo Derek,' because of the movie '10.' He said, 'You can't find Bo unless you like Bo.'"
What did Narron think of the cornrows?
"He won a World Series with it, I guess it's okay," Narron said.
Would Narron ever don the look himself?
"If we win the World Series, I'll get it," Narron said. "I set my goals low."
Odds and ends:
Left-hander Brandon Claussen will have arthroscopic surgery on his left shoulder on Monday, the club announced. Cincinnati medical director Tim Kremchek will perform the procedure.
First baseman Scott Hatteberg collected his 1,000th career hit with a first-inning single Tuesday against St. Louis.
Aaron Harang (12-7, 3.53) will pitch for the Reds against the Cardinals' Chris Carpenter (10-6, 3.06) when the series continues Wednesday at 7:10 p.m. ET.
