"It's not too bad at all," Venters said. "Apparently I've got to hit it off of me or the other team to get anybody out. But I feel fine."
Venters was the pitcher on Sunday against Tampa Bay when Carlos Pena of the Rays was hit by a batted ball and called out to end a Tampa Bay threat.
On Wednesday night, Venters was struck in the calf by a line drive off the bat of Reds first baseman Joey Votto in the eighth inning. Venters recovered in time to find the ball and throw Votto out at first. Manager Fredi Gonzalez and trainer Jeff Porter came out to check on Venters, who remained in the game and delivered an intentional walk to Brandon Phillips.
Eric O'Flaherty replaced Venters and got Jay Bruce to hit into an inning-ending double play.
Venters has eight holds on the season, but has had trouble with his command, allowing nine of the 18 first batters he has faced to reach base. He's allowed 20 hits, hit four batters and walked seven in just 15 1/3 innings this season.
Venters spent pregame Thursday looking at video comparisons of himself from last season and this season in an attempt to find any issues.
"I'm having a hard time getting the ball to sink, it's staying up in the zone," Venters said. "My mechanics feel great but the ball's not sinking enough so I've got to try to find something. I must be doing something different."
