Talking about the special baseballs that had to be put in play whenever Bonds came to bat, the left-hander deadpanned a facetious description.
"They just have a 'B' and number on them and a picture of Barry, too," Halsey said. "And if you look into his eye, he winks at you."
That doesn't sound like a guy unnerved whatsoever by what happened to him, and he showed it Saturday by pitching a solid 6 innings and allowing just two runs, the momentous home run to Bonds in the second inning and another to Mike Matheny in the seventh.
Bonds crushed a 1-1 Halsey fastball leading off the second for the home run that tied him for second on the all-time list with Babe Ruth. But Halsey struck Bonds out the next time the left-hander faced the Giants star an inning later.
"I made a bad pitch, I left a fastball over the middle of the plate ,and he punished me for it," Halsey said. "As soon as the pitch left my hand, I was thinking it was probably going to be bad news."
But Halsey said he shook it off very quickly and didn't obsess over the significance of it.
"Anytime you give up a home run, you're going to get upset about it. But if you let that home run determine how the rest of your game goes, you're doing yourself a disservice. So I just tried to shake it off and make good pitches to the next guy.
"Obviously, you guys think it's a pretty big deal. For me, it's a home run that I gave up, and I know it's a big deal for him. But for me, it's not who I am. It's just another day at the ballpark."
Of Bonds himself, Halsey said he was indifferent to all the allegations about steroid use against him.
"As far as all the controversies surrounding Barry Bonds using performance-enhancing supplements or whatever, he's a baseball player, and no matter what you use, you don't hit balls like that unless you're tremendously gifted," he said. "And he is."
MORE A'S ON BONDS: Jay Payton was in right field when Bonds no-doubt historic homer sailed into the bleachers.
"I was hoping the ball would come back on the field so I could get it and throw it in, but unfortunately it didn't," Payton said. "It's part of history so it's exciting for the players to be a part of it. Unfortunately, we came up on the short end."
Said A's manager Ken Macha, "I've got a lot of respect for him as a player. I think he's one of the greatest home run hitters of all-time, if not the greatest if he plays some more. It's quite an accomplishment."
ONE-HOPPERS: Despite a ninth-inning rally, the A's saw their five-game winning streak snapped. The pivotal play came with the score tied 2-2 in the bottom of the ninth when Jason Kendall lined into a double play at third base with two runners in scoring position. "We got a line drive to win the game, so that was kind of tough luck there," Macha said. ... The A's manager also said left-hander Joe Kennedy would have gotten the call against two left-handed hitters when the Giants scored two runs in top of the 10th if Kennedy had not been on the disabled list. ... Today's A's starter Joe Blanton was 1-0 with a 2.13 ERA in two starts against the Giants last year but has never faced Bonds.
