Luhnow wouldn't confirm the club had indeed submitted a bid.
"We continue to have interest in Soler and that's the most I can say right now," Luhnow said. "We're aware of the process and if there's anything report, we will let you all know."
Soler must sign with a Major League club before July 2 or he will be subject to new CBA guidelines that will limit spending on international prospects to $2.9 million per team without penalty. Luhnow said previously he expects the signing process to happen quickly.
