2007 Cincinnati Reds season

The 2007 Cincinnati Reds season was the 138th season for the franchise in Major League Baseball, and their fifth season at Great American Ball Park in Cincinnati. The Reds failed on a bid to win the National League Central, falling out of serious contention by midseason and finishing in fifth place with a 72–90 record.

Following an 11–7 loss to the St. Louis Cardinals on July 1, general manager Wayne Krivsky fired manager Jerry Narron and named advance scout Pete Mackanin interim manager. It was the second managerial change of the day, following the resignation of Seattle Mariners skipper Mike Hargrove. The Reds won Mackanin's first game at the helm, 7–3 over the San Francisco Giants on the strength of a grand slam by Brandon Phillips.

The season also included highlights such as the Reds 2004 first-round draft pick, right-handed starting pitcher Homer Bailey making his MLB debut against the Indians on June 8. He pitched 5 innings, gave up 2 earned runs, struck out 3, and walked 4.
