The Houston Astros faced the San Francisco Giants in a game that saw two firsts for the defending champions. For the first time this year, the roof at Minute Maid Park was open. Unfortunately for the hosts, they were shut out by the Giants, with the visitors winning by a 2-0 score.San Francisco managed to hand Houston its first blanking of the season, although it could have been worse as they stranded 10 runners on base, while the Astros escaped three bases-loaded jams in the game.It was not a good night for the Astros. Their pitchers handed out nine walks, including a career-high five from starter Hunter Brown, who lasted just 4-1/3 innings after throwing 96 pitches and allowing two earned runs on four hits.San Francisco's starting pitcher Anthony DeSclafani was excellent. He allowed just three hits over eight innings, which was Houston's lowest hit count in a game this season. Camilo Doval then tossed a clean ninth for his fourth save.htxrob@htxmma@astros We need to wake up boys24@astros We need to wake up boysdonflacco@El_Drago20@astros Just broke my tv goodnight@astros Just broke my tv goodnight https://t.co/veSg0922rrCozy Ŧ 🌵@sad_cozy@astros Pitiful2@astros PitifulDespite their frustration at the loss, Astros fans were also upset with the umpiring crew, particularly regarding three mound visits by the Giants in the bottom of the ninth inning.However, not all fans were willing to blame the umpires for the loss.MALDONADO SUCKS@MousePad05@astros I’m confused as to why the Giants got 3 mound visits in the 9th when they had 2 remaining. Yordan should’ve probably gotten an automatic ball which would’ve put him on but whatever. Go out and win tomorrow.6@astros I’m confused as to why the Giants got 3 mound visits in the 9th when they had 2 remaining.
