Giants shift Adrian Houser to bullpen after 6-3 loss to Marlins

The San Francisco Giants fell 6-3 to the Miami Marlins, committing four errors and seeing starter Trevor McDonald endure a short three‑inning outing that included three walks, three hit batters and five runs allowed. Manager Tony Vitello responded by moving right‑hander Adrian Houser out of the rotation and into the bullpen; Houser had posted a 5.73 ERA in 14 starts and expressed disappointment at the role change. The move also clears a spot for the imminent return of recently injured starter Tyler Mahle. Miami’s Max Meyer earned his eighth consecutive win, improving to 8‑0 with a two‑run, five‑inning performance that set a new franchise record for consecutive opening‑season victories. Giants outfielder Lee Jung‑hoo continued his surge in the National League batting race, collecting two doubles to raise his average to .331, while the team’s offense was hampered by defensive miscues. The series highlights ongoing challenges for the Giants’ pitching staff and the front office’s consideration of further roster adjustments.
