Who’s msising from the grand‑slam narrative?

The report does not confirm whether any Cubs players contributed to the grand‑slam tally, leaving the Cubs’ offensive response unclear. Additionally, the exact number of grand slams the Giants have hit this season beyond the six‑in‑20‑days stretch remains unverified.

According to the source, the Giants also became only the third team since 1901 to hit a grand slam in every leg of a three‑city road trip, joining the 2023 Houston Astros and the 1983 California Angels. notably, new third‑base coach Gary Pettis was part of both historic teams, serving as a coach for the Astros and as a player for the Angels.
