The San Francisco Giants extended their best month in exactly two years with a victory at Arizona on Friday, given a huge boost by rookie outfielder Austin Slater and left-hander Andrew Suarez. At 17-10, the Giants are having their first winning month since June 2016, and with a victory in the second game of the three-game series Saturday, they will have one more victory than they had that June. Slater had three hits, including two RBI doubles, in a Giants 2-1 victory on Friday, his sixth day back on his fourth recall from Triple-A Sacramento this season.
