"[Hurdle] said he would try to get him an inning in the middle," Baker said Sunday morning. "He wanted to start him but he has some wonderful options."
It appeared the choices were down to the Brewers' Ben Sheets and the Cubs' Carlos Zambrano. Two other would-be choices -- Arizona's Brandon Webb and San Francisco's Tim Lincecum -- are starting on Sunday for their respective teams.
Volquez, a 25-year-old right-hander, is 12-3 with a NL-leading 2.29 ERA in 20 games, including 19 starts, this season. He came into the day tied with Lincecum for the NL lead with 126 strikeouts. Volquez is second in victories behind Webb.
The Reds are waiting to see if Volquez pitches Tuesday before deciding on when he will make his first second-half start.
Had he started on Tuesday at Yankee Stadium, Volquez would have been the first Reds All-Star starter since Jack Armstrong in 1990.
Bronson Arroyo was the last Reds pitcher to appear in an All-Star Game, in 2006 at Pittsburgh. He threw one scoreless inning of relief.
