PHOENIX (AP) Keyvius Sampson earned his first major league victory, Cincinnati hit three home runs and the Reds beat Arizona 4-1 Saturday on the night the Diamondbacks retired new Hall of Famer Randy Johnson's No. 51.

All the Cincinnati runs came on homers by Eugenio Suarez, Brandon Phillips and Marlon Byrd, whose solo shot in the ninth was his 150th career home run.

Sampson (1-1) gave up a first-inning run and the Diamondbacks never scored again. He went six innings and allowed four hits, struck out four and walked three.
