COLLEGE STATION, Texas — USC’s Andrew Lamb is too young to remember his father Mike’s five postseason home runs in the majors. Yet, his dad has shown them to him more than a few times over the years.

With his dad at Blue Bell Park after taking a red-eye flight from Los Angeles, Andrew delivered a 421-foot blast that his dad and the USC Trojans won’t soon forget.

Lamb’s majestic, three-run blast helped USC rout Lamar 19-6 to keep the Trojans alive at the College Station Regional.

“Off the bat, it was crushed,” USC center fielder Walter Urbon, who finished a triple shy of the cycle, said of Lamb’s homer. “We were like, ‘It was so far gone.’ Then … you’re yelling and screaming and just enjoying the energy in the moment and cheering for him and everything. It was beautiful.”

The Trojans (44-16) had plenty to celebrate after scoring a season high for runs. Lamar (34-27) had never given up more than 16 runs in 39 previous NCAA regional games.

Lamb finished two for four with a walk and four RBIs. Adrian Lopez, who opened the scoring with a two-run home run, also finished a triple shy of the cycle.

USC coach Andy Stankiewicz pulled some of his starters as the Trojans pulled away, but he let Lopez and Urbon chase the cycle.

“We talked about it,” Urbon said of the cycle. “I think after my third hit somebody said it to me, and I had no clue. It was in the back of my head for my next at-bat until I got back in the box, and then I forgot about it.

“That would have been cool. We were making jokes about theoretical possibilities and whatever hit, like keep running or fall. Just get to third.”

The Trojans, who lost their opener Friday night to fall into the losers’ bracket, advanced to play Sunday at 1 p.m. They’ll face Texas State, which lost to Texas A&M 17-2 on Saturday.

The Trojans jumped to a 16-0 lead before Lamar scored five runs in the bottom of the fifth. USC scored five in the first and two in the second. Urbon’s grand slam highlighted a five-run rally in the fourth. Needing a triple to complete the cycle, Urbon capped a four-run rally in the top of the fifth with a sacrifice fly.

Without a doubt, the most impressive blast was the one Lamb hit in the first.

“It’s always good, a proud dad moment for sure,” Mike Lamb said of his son’s 11th home run of the season. “I know what it feels like to be in the box and just to hit a ball like that and the relief that it’s going to be a base hit.

“And then for it to be a home run, it’s a great feeling running around the bases. I haven’t forgotten what that feels like. So for him to feel it, it’s pretty cool.”

After watching his daughter Brooklyn win a CIF softball title with JSerra on Friday night, former Astro Mike Lamb caught a red-eye to see his son Andrew play for USC in the College Station Regional.

Mike Lamb hit 69 home runs over parts of 10 seasons in the majors. He added five more in the playoffs. He hit his first MLB postseason home run in Game 1 of the 2004 National League Championship Series for the Astros three days before Andrew was born. Andrew was only 4 days old when his dad hit his second home run of the 2004 NLCS.

Andrew had barely celebrated his first birthday six days before Mike homered in the 2005 World Series.

“I don’t know if I was old enough to remember being there, but yeah I’ve seen them a couple of times,” Andrew Lamb said. “He likes to show off a little bit, but rightfully so. The guy made it. I respect him for it. It’s good to follow him along the same path.”

Mike Lamb had a good excuse for missing the Trojans’ loss Friday night. He was in California watching his youngest of three kids, Brooklyn, win a CIF softball title with JSerra.

The elder Lamb then boarded a red-eye for Houston. He arrived in Houston at 6 a.m., rented a car and drove down to College Station.

“He’s been there every step of the way,” Andrew Lamb said of his dad. “He’s helped me out mentally, physically, training, everything. It’s my dad. It’s great to have him, but with him always in the stands it always gives me an extra confidence boost. For him to fly out like that is pretty special.”

Mike Lamb definitely liked what he saw.

“I always tell [Andrew] that he’s better than me at the same age,” Mike Lamb said. “It’s starting to even out now that he’s 21, but yeah, I don’t know that I hit too many balls like that ever. So he’s doing well. I’m very proud of him.”
