"I was very pleased. Great news," Berry said after the Reds took a 6-2 victory over the Cardinals. "I won't forget this day. And a nice win to top it off."
Berry was diagnosed with cancer in his tonsils and lymph nodes during Spring Training in March and took a leave from the club to undergo chemotherapy and radiation treatment. He returned to part-time work and traveling in June before resuming coaching at third base in mid-July.
On Wednesday, Berry underwent the PET scan exam to see if the treatments were successful.
"I went through a 16-inning game [Wednesday] night, knowing the test was over but not knowing the results," Berry said. "At third base, I was focused and locked in, but when I got into the dugout, I was thinking about it. Of course, anybody would. But I wasn't overly nervous. I felt good about it.
"The first thing they said was the scans came out really clean, really nice."
