After an idea from their daughter-in-law and help from the Angels, each parent wore a shirt that had half of Jeff's Dodgers jersey and half of Jered's Angels jersey sewn together.
"It was very emotional," Gail said after the Dodgers beat the Angels, 6-4. "There was no downtime, so before you know it, the next one is coming out and you are rooting for him. So, it was exciting."
While Jered Weaver pitched 5 1/3 innings, giving up 10 hits and six earned runs to get the loss, brother Jeff picked up the win in five-plus innings of work, giving up six hits and two earned runs.
"It is not a comfortable feeling," Gail said. "You want them both to do well because they are doing the best that they can, and we are just rooting for both of them.
"We were hoping somehow that they can both get a win, but we know that isn't possible, so you just keep rooting for them, and whatever happens happens."
Although the entire Weaver clan was not at the game, the outpouring of support from the entire family has been something Gail will not soon forget.
To celebrate the unique occasion, the family decided to a have a get-together with family and friends after the game to take in the moment for what it was.
"I am going to remember all the support we have received from family and friends and to see my sons out there being able to share this together," Gail said. "It is a unique situation and I know they enjoyed it, so we are, too."
Understanding how demanding the past few days have been on both of her sons, Gail could not have been more proud of how each handled themselves.
"They both deserve this because they work very hard. It isn't an easy situation," Gail said. "I wish they both could have got a win. It just doesn't work that way."
