But the theme in the Padres' clubhouse on Monday night was that -- no matter the score and no matter the occasion -- it was simply one defeat in a long season.
"They didn't win the series today, they didn't win the month today -- they won one game today," said Padres manager Andy Green. "I think we try to diminish the impact of one loss. It's not really that big in the course of 162."
Managing his first big league game, Green didn't see any reason to address his team after the loss. In his eyes, there was no need to re-hash what was already in the past.
Still, Green conceded that "it probably does sting more than normal," coming on Day 1.
"Opening Day is special," Green said. "It'll always be special. Nobody wants to come out and lay an egg on Opening Day and get beat, 15-0. Nobody in baseball wants to do that. It still is one of 162."
Padres first baseman Wil Myers, who had one of the club's four hits on the night, said he'd already moved past the defeat.
"It'd be harder more so late in the year," Myers said. "It's one of those things: That's probably going to be our worst loss of the year, and we got it out of the way. It's not something we dwell on, we sit there and we talk about. It's just one of those things that happens."
Said right fielder Matt Kemp: "We play every single day. After this game is over, you just turn the page. It's just one of those games where it's going to happen. It just so happened to happen on Opening Day."
That refrain may ring hollow to some, but Monday's game did have a bit of a lose-the-battle feel to it. Trailing, 8-0, with a lights-out Clayton Kershaw on the hill for Los Angeles, Green gave 22-year-old right-hander Luis Perdomo, the club's No. 12 prospect, a baptism by fire.
In front of a packed house at Petco Park, Perdomo, a Rule 5 Draft pick who had never pitched above Class A Advanced, made his debut and was hit hard for six runs in one-plus innings. Right-hander Colin Rea, who will start on Friday in Colorado, followed Perdomo by making his first career relief appearance, preserving the 'pen for Tuesday and beyond.
After the most lopsided season-opening loss in franchise history, Tuesday and beyond are exactly where the Padres are looking.
"In the grand scheme of things, it's one loss out of 162 games," said starting pitcher Tyson Ross, who took full responsibility for his performance -- eight runs (seven earned) and nine hits over 5 1/3 innings. "Lopsided score, all the bad things that happened today -- at the end of the day, it's still one loss.
"Tomorrow, we've got James [Shields] on the mound. We've got a chance to come out and even the series and eventually win it. It wasn't the best showing today. But I think tomorrow's going to be a better day for us."
