Votto, Volquez depart due to ailments

Slugger out with dizziness; righty leaves with back spasms

SAN DIEGO -- Two Reds starters exited Saturday night's game prematurely.

In the fourth inning, Reds first baseman Joey Votto left with a recurrence of the mild dizziness that held him out of Wednesday's game in Arizona, and two innings later, starting pitcher Edinson Volquez came out with mild spasms in his mid-back.

Votto, who will be examined in Cincinnati when the team returns home on Sunday, started the game and flied out twice before being replaced by Adam Rosales in the fourth. It's the second time in five days Votto has been pulled from a game after feeling dizzy, as he exited Tuesday's contest in the fourth inning as well.

"Joey said he got dizzy," Baker said. "That's a tough blow right there. We're going to send him off to find out why he's having that dizziness."

Volquez recorded two flyouts before throwing six straight balls and walking off the mound in pain. Manager Dusty Baker and the team trainer visited with the pitcher, electing to bring in Mike Lincoln.

"It was like something grabbed my back," Volquez said. "It's tight right now. On the last three pitches I threw, I felt it, like, grab at me on both sides of my back."

Volquez was optimistic about making his next start.

"I hope so," Volquez said. "I hope it gets better for my next start. We'll see what happens."

Flu-like symptoms have caused Votto to miss five starts since May 7, but the 25-year-old slugger returned to the lineup Friday night and was healthy enough to belt a solo home run -- his fifth of the season.

In 32 games this season, Votto is hitting .366 with 27 RBIs and entered Saturday's contest ranked second in the National League in hitting. He has hit safely in 23 of his 32 appearances and has reached base in 29 of those games.

Over seven starts prior to Saturday, Volquez posted a 4-2 record and 4.45 ERA while holding opponents to a NL-best .182 batting average.
