"It was awesome," the Arizona native said prior to Tuesday's game. "Especially when they announced us. When they said, 'And your visitors, the Seattle Mariners,' and everybody was booing, I was like, 'Oh, OK. There you go.' Once they were calling their guys out, just the roar of the crowd and 40,000-plus people, it just kind of hits you right there. Especially being down on the field, everything comes toward you.
"That was a big moment, especially all the theatrical stuff, the fireworks, the fire coming out of the rocks. But after that, I was fine. I just wanted to soak it all in. I was getting ready in the sixth or seventh inning in case I needed to pinch-hit. I was ready. The nerves started to settle down. Tonight, I feel like I'll be a little nervous, but after that first pitch, that first fly ball, that first hit, then it'll just be normal after that."
Romero, a standout at Oregon State in 2009-10, said he found comfort in finding his parents, aunt and uncle and girlfriend in the sellout crowd of 44,152 on Opening Day.
"That kind of calmed me down a little because they were all at my Spring Training games," said Romero, who went 0-for-4 in the Mariners' 8-3 win over the Angels. "So to see them there gave me a sense of comfort."
