• Vogt, quite familiar with Sacramento's staff, spoke highly of righty Sonny Gray when asked about Oakland's top pitching prospect on Tuesday.
"Sonny has an electric arm," he said. "He's the real deal. He's got great stuff. He's got three pitches. He's still developing his command a little bit but his stuff is there. He's going to be something special."
Gray, the A's 2011 first-round Draft pick, is 7-5 with a 2.85 ERA in 14 starts for the River Cats. He has 90 strikeouts next to 29 walks in 88 1/3 innings.
