Arizona (42-42) held off a late rally by San Francisco (35-49) to secure a series opening 5-4 win on Monday to continue the Diamondbacks seven-game winning streak over the Giants.
The Diamondbacks have outscored the Giants, 37-19 during their seven meetings this season. Although, the past two meetings have been decided by one run each. Arizona’s win snapped a three-game losing streak and makes them 4-6 over the past 10 games. In June, Arizona’s offense has scored the third-fewest runs (91) while hitting .222 (27th) to go along with a pitching staff that owns a 5.02 ERA (26th).
San Francisco is 4-6 in the past 10 as well and middle of the pack across the board in June. In the last 10 games, the Giants have surrendered three or less runs six times, but they have only scored four or more runs three times in that span. The Giants are hitting .261 (10th) as a team with a 4.30 ERA (17th) and .245 OBA (T-15th) across the month. One random statistical highlight for the Giants in June has been the pitching staff allowing the second-fewest home runs (22) so far.
