The Giants will send left-hander Andrew Suarez (4-6, 4.11 ERA) to the mound against the D-backs on Saturday for the 5:10 p.m. PT start. Suarez made his Major League debut against Arizona in a loss on April 11 and had one of his best outings in a victory at Chase Field on June 29, when he gave up one run and seven hits in six innings. Five of those hits did not leave the infield. The D-backs will start Clay Buchholz (4-1, 2.65).
