Bobby Heck and scout Doug Deutsch are still negotiating with first-round pick Jiovanni Mier, a high school shortstop from southern California.

"It's been very positive," Heck said. "Doug Deutsch has had multiple meetings with the family since his selection, and we've been given all indicators it's going to happen sooner than later."
