"We'll have to bring him out a few more times," utility man Willie Bloomquist said.
On Wednesday, Speck, an 11-year-old patient at Phoenix Children's Hospital, his mother Lisa and 11-year-old friend Max Siegel were the guests of Bloomquist. Before the game, Speck asked Bloomquist if he would point to him in the stands if he hit a home run.
"I said, 'I doubt I'm going to hit a home run. I don't hit very many home runs, but if I do, yeah, absolutely,'" Bloomquist said.
"And he goes, 'No, you're going to hit one out tonight, so when you do, will you point to me?'"
Speck said the prediction was simply a product of his observation skills.
"I saw him hitting in batting practice and he looked pretty comfortable," Speck said. "It just kind of came to me that he was going to hit the home run."
In the third inning, Bloomquist did hit the home run, to left field off Giants left-hander Madison Bumgarner.
"Rounding second, it was kind of an emotional thing for me," Bloomquist said. "These kids that I have out are dealing with a lot of stuff and for a kid to make a statement like, 'Hey, you're going to hit a home run,' it's like, 'Wishful thinking, kid,' but for it to actually happen?
"He was probably going crazy, so that's a cool thing."
Abe's mother Lisa said as much.
"They were jumping up like crazy nuts," she said.
As Bloomquist rounded the bases, Speck turned to his friend Max and asked if he thought he would point to them.
And when Bloomquist crossed home plate, he pointed at Speck and his guests, seated behind the D-backs dugout in Section 129.
"It was cool," Speck said.
"It was special," Bloomquist said.
And it was something the 33-year-old veteran thinks might have been out of his power.
"I really couldn't believe that it happened," Bloomquist said. "It was obviously a little help from the powers above to give the kid a good night like that."
Bloomquist usually brings out one kid each homestand and said he decided to reach out when he signed with the D-backs.
"It's something I do for the kids," he said. "I've been blessed to have had the opportunity to play in my hometown, and if I can make a night for one kid where he doesn't have to think about being sick, it means that much more to me."
