Arizona manager Kirk Gibson earned his 337th victory Wednesday afternoon, tying him with Bob Melvin for the most in franchise history.
Gibson guided the D-backs to a 5-4 win over the Reds at the Great American Ball Park.
Both skippers accomplished the feat in 677 games. Gibson has 54 games remaining this season to not only put some distance between Melvin and himself in the club's record books, but to right the ship in Phoenix.
Gibson had a winning percentage of at least .500 in each of first three full seasons, winning National League Manager of the Year honors in 2011. Melvin finished with a winning record twice in five seasons at the helm in Arizona.
Melvin managed the D-backs from 2005-09, compiling a 337-340 record in parts of five seasons. He was named NL Manager of the Year in 2007 and has led the A's to two consecutive Ameican League West titles, taking home the AL Manager of the Year Award in 2012.
