RENO - The Diamondbacks optioned Daniel Schlereth to triple-A Reno on Wednesday night.
Schlereth is 0-2 with a 7.56 ERA in 10 games with Arizona this season. He was a first round pick by the D'backs in the 2009 MLB draft.
Schlereth is the son of Mark Schlereth, a former NFL lineman and current ESPN Football analyst. Mark won two Super Bowls with the Denver Broncos, and another with the Washington Redskins.
He was sent down to AAA to make room on the roster for Justin Upton, who was activated from the 15-day disabled list.
Schlereth will join the Aces on Thursday in Las Vegas for their series with the 51s.
