Arizona Diamondbacks starting pitcher Ian Kennedy announced prior to Monday's three-game series opener versus Miami that he dropped his appeal and immediately began serving a 10-game suspension.

Kennedy, 28, received the harshest punishment as a result of his involvement in a brawl between the Diamondbacks and Los Angeles Dodgers last Tuesday.

Kennedy plunked Yasiel Puig and Zack Greinke, with the latter partly setting off the benches-clearing melee. The length of the suspension is the longest issued to a pitcher since Kansas City's Runelvys Hernandez got 10 games in 2005.

The right-hander has a 3-4 record this season with a 5.21 ERA in 14 games.
