Manager Bruce Bochy said he has discussed the possibility of promoting Brown or Kieschnick with general manager Brian Sabean. The fact that both players remain with Fresno speaks volumes.
"If somebody's ready who can help us, you make that call," Bochy said Thursday. "If we don't think they're ready, you don't want to bring them up."
Brown's problems with right-handed pitching are well-documented. The Giants' No. 1 selection in the 2010 First-Year Player Draft began the season in a horrific slump but has lifted his batting average to .246 with 11 home runs, 40 RBIs and 11 stolen bases in 83 games entering Thursday.
Kieschnick was hitting .261 in 81 games with 11 homers, 49 RBIs and a .484 slugging percentage. Bochy couched his remarks about Kieschnick in general terms.
"He still needs time down there with the bat, and I think that's pretty much it," Bochy said.
