"The first one, just for mom, would be in the ribs," Moyer joked. "And I know what his response would be: 'It wouldn't hurt.'"
The Moyers are a baseball family. They have been for years. The Chicago Cubs drafted Moyer, 47, in the sixth round of the 1984 First-Year Player Draft. The southpaw has been in the big leagues since 1986, and is 6-5 with a 3.98 ERA in 11 starts this season. But he learned Tuesday that the Twins drafted Dillon, 18, in the 22nd round of the First-Year Player Draft.
Dillon, who is a shortstop, has a college commitment to University of California-Irvine, but could sign with the Twins.
It is a proud moment for Moyer, whose family has only known a father who has played professional baseball.
"I thought it was pretty cool when Ken Griffey Jr. and Ken Griffey Sr. were on the same team," Moyer said. "You see the Hairston brothers are playing together. That's pretty unique. That's pretty cool. But a father-son thing? I think that's got to be pretty cool, whether you're playing together or opposing each other. I think if you're opposing each other, somebody's going to have some bragging rights."
Moyer has never actually pitched to Dillon. He has thrown to him, but he has never really, truly pitched.
"It's tough during the season," Moyer said. "I went back [home] at one point early in the season and I had to throw. I threw to one of their catchers. I said, 'When I retire, I'm going to come out in the fall. I'd love to throw to you guys.' I think that would be fun for me. I think that would be fun for them, competitively speaking."
Moyer said it is rewarding to see Dillon grow up into a successful athlete.
"Dillon has worked hard to get to where he is," Moyer said. "I'm sure his goal is to play professional baseball. This is all he knows. His younger brother, Hutton, who will be a junior, [also has] aspirations to play. But we also try to hit home that school is very important. We know the reality. It's not easy to get to this level. If you get to this level, it's difficult to stay here. Having an education, something to fall back on, I think is very important. I think Dillon understands that."
"It was pretty cool, but I'm not there yet," Dillon added. "It's going to be tough [to make a decision]. But either way, it's a win-win situation."
Phillies manager Charlie Manuel is impressed with the baseball talents of Moyer's three sons: Dillon, Hutton, who is 17, and McCabe, who is 6.
"Mac's got the best arm of a 6-year-old kid I've ever seen," Manuel said. "Have you seen him? This kid is off the charts. He's got a better fastball than Jamie. He could be another Joe Nuxhall."
