Cantu's fifth-inning blast put him in the record books. He became the first major league player to record both a hit and an RBI in each of the first nine games to start a season -- bettering a record set in 1921 by George "Highpockets" Kelly of the New York Giants.
Carroll's performance came in his first game back from a stint on the disabled list, while John Baker contributed two hits and two RBI for the Marlins, who had lost the first two contests in the four-game series against the Reds.
Chris Volstad (1-1) got the win after hurling 6 2/3 innings, allowing three runs on five hits, while Burke Badenhop notched his first career save.
Paul Janish belted a two-run homer for the Reds in the loss. Cincinnati starter Homer Bailey (0-1) lasted only 5 1/3 innings.
