On 11 July, Gerrard made his debut for the club in a mid-season friendly match against Club América, playing the first 45 minutes of the match in which the Galaxy won 2–1. Three days later, Gerrard made his competitive debut for LA, coming on at half time for Ignacio Maganto in a 1–0 loss at Real Salt Lake in the US Open Cup quarter-finals. He made his MLS debut on 17 July, scoring once, while assisting one goal of his former Liverpool teammate Robbie Keane's hat-trick, during a 5–2 defeat of fellow Californians the San Jose Earthquakes at the StubHub Center. That month, Gerrard was one of the 22 players to be named to the 2015 MLS All-Star Game roster. He made 13 appearances across the regular season, scoring one more goal, the team's last of a 3–2 home win over FC Dallas on 27 September.
