Romo was a part of the 2010 Giants team that won the World Series over the Texas Rangers. In 2012, he shared closer duties with Santiago Casilla during the regular season after Brian Wilson was injured early in the year, and picked up 15 saves. He was the closer in the postseason, and picked up saves in Games 2 and 3 of the 2012 World Series, both times completing 2-0 wins over the Detroit Tigers by pitching a scoreless 9th inning. He was again called upon in Game 4, after the Giants had taken a 4-3 lead in the top of the 10th. He dispatched the Tigers in brilliant fashion, fanning Austin Jackson, pinch-hitter Don Kelly and Miguel Cabrera in order to pick up his third save as the Giants completed a four-game sweep.
On January 1, 2013, he was involved in an incident in Las Vegas, NV, when he failed to produce appropriate identification to clear security at the city's airport. The incident degenerated, police intervened, and Romo was handcuffed, detained briefly, and issued a citation for violating airport rules. He issued a public apology two days later when the incident became public. He set a personal mark with 38 saves that season and was named to the All-Star team. In 2014, he was part of a third World series-winning team when he went 6-4, 3.72 with 23 saves during the regular season. The relatively high ERA resulted in his losing the closer's job to Casilla during the season. In the postseason, he went 1-1 with no saves in 9 appearances, giving up 1 earned run in 7 innings. That run was a walk-off homer by Kolten Wong of the St. Louis Cardinals that cost the Giants Game 2 of the NLCS on October 12th, but he was impeccable otherwise. In 2015, he was a set-up man for Casilla, going 0-5 but with a solid ERA of 2.98 and 34 holds in addition to 2 saves. He was then injured early in the 2016 season after making four appearances in early April and did not return until early July. The Giants had the best record in the majors at the All-Star break, but most of his 40 appearances came in the second half, when the team struggled badly and barely limped into the postseason as the NL's second wild card team. He was 1-0, 2.64 and saved 4 games, but even though Casilla struggled down the stretch, he was not given back his former role as closer. In the NLDS against the Chicago Cubs, he was part of a complete meltdown by the team's bullpen, giving up 3 runs in 2 innings over 2 appearances.
