"I had a good conversation with him about making adjustments and then applying them . . . both on the offensive side and the defensive side," Sandberg said.
Sandberg said Brown has developed some poor mechanics at the plate.
"He's really developed an uppercut swing and he's just missing too many of his pitches, and it puts him in a hole in a lot of at-bats," the manager said.
"I don't know if you can teach all of the instincts [on defense], but you can teach game situations and anticipating balls, expecting balls to be hit to you on every pitch," Sandberg said. "That's a discipline, that's a focus. A little bit of that might be instincts, but the other part of that is just an all-out focus and discipline and practice."
What kind of reaction did Sandberg receive from Brown?
"I see somebody that wants to make a correction and understand it," Sandberg said. ". . . I do see a guy that realizes he has to make adjustments."
John Mayberry Jr. got the start in left field. He was 3 for 26 (.115) in his previous eight starts.
Brown pinch-hit for Mayberry in the seventh and singled, then scored the tying run to make it 3-3.
Help from the farm
Sandberg said that Lehigh Valley righthander Sean O'Sullivan will join the team and pitch the second game of Saturday night's doubleheader against David Hale and the Atlanta Braves.
O'Sullivan, 26, is 10-16 with a 5.89 ERA in 50 career big-league games with the Los Angeles Angels, Kansas City, and San Diego. He is 3-6 with a 4.31 ERA in 15 starts at Lehigh Valley this season.
