He was traded from the Padres to the Chicago White Sox in 2005 at the trade deadline. He went on to hit a big homer for the Sox in a World Series game against the Astros, earning a World Series ring.
"Well, it was interesting just because I didn't expect it," Blum said. "I was miserable. I didn't want to leave. The triplets just got out of the hospital, and I was here with a ballclub I enjoyed. It was pretty tough."
Blum had to leave his wife with four small children the very next day for the White Sox.
"I think it was the last trade we did, too, totally unexpected," Blum said.
Blum has been dealt three times in his career. And it never gets easy.
"Just the anticipation every year; you never know who it's going to be," Blum said. "It kind of takes over a little bit when the clubhouse guys start talking and everybody with their conspiracy theories.
"But some of those things are out of our control, unless you have a no-trade clause in your contract. So, we just kind of sit back and wait and see what happens and deal with it when it does happen."
Outfielder Jose Cruz Jr. was traded at the trade deadline in 1997 from the first team he broke into the big leagues with, the Seattle Mariners.
Cruz went to the Toronto Blue Jays that year. Cruz was traded a few more times, until he signed with the Padres in 2006 as a free agent.
"It's weird," Cruz said of the process. "You want to stay somewhere and stay put and be a part of something great, and you get yanked out of your comfort and go somewhere else. Sometimes it works out great, and sometimes it's not as good.
"It's definitely a hassle, it's not easy. I've been traded now quite a few times. The first time I got traded I didn't have kids, and the other times I have."
This year's trade deadline brought a few new faces into the clubhouse. But it also sent a couple beloved players, such as reliever Scott Linebrink and infielder-outfielder Russell Branyan out to make room. Linebrink went to the Milwaukee Brewers, while Branyan was released.
"You know it's tough," starting pitcher Jake Peavy said. "We're family in here. It's tough when one of your family members, so to speak, gets traded. You're not going to be around him and see him much.
"But like I said, it's a business, and you've got to take it for what it is and realize, you can be the next guy out of the door. It's tough to do, but we do it the best we can."
As Blum said, "'Tis the season."
Hairston facing old team: Outfielder Scott Hairson was acquired by the Padres last Friday from the Arizona Diamondbacks. It was just days ago that he was on their roster, and now he's facing them at PETCO Park.
"It's quicker than I thought it would be," Hairston said of the immediate encounter. "Hey, I get to see some of my old friends. My attitude toward playing is going to be the same. No matter what team I play for, I have a job to do. At the same time, I would love to win, and I'm a Padre now."
Hairston, who is batting .219, has yet to record his first hit with the Padres. Although he is one of the new guys in the clubhouse, he does know a few players already: Mike Cameron, Cruz and Adrian Gonzalez. Although this was Hairston's first Major League trade, he isn't complaining about the outcome. He actually smiled when they told him where he was headed.
"I felt if it was going to happen, it was going to happen that week, last week, and it did," Hairston said. "I don't think I was shocked. I was surprised.
"Well, I think out of any team to choose from, this would be it -- great group of guys, great franchise, a winning franchise and a beautiful city too. I get a chance to play here and make this my home."
So how does he feel about taking on his old teammates?
"I want to sweep them," Hairston said.
Stauffer back: Padres starting pitcher Tim Stauffer made his first appearance for 2007 on Sunday against the Houston Astros.
Stauffer, who was recalled from Triple-A Portland to fill in for an injured Chris Young, tossed 3 2/3 innings for a no-decision.
He allowed seven runs on just four hits.
"Obviously, not thrilled with it," Stauffer said of his performance on the mound. "Felt pretty good going into it, but ran out of gas a little quicker than I was hoping. I guess the big thing was that we won, but the offense really picked us up that day."
Stauffer also contributed to the offensive outburst in an 18-11 win by adding a two-run single.
It is uncertain how long Stauffer will be with the Padres.
"No idea," Stauffer said. "I just know I'm here right now and I'm just playing it by ear."
On deck: The Padres play the second game of a three-game series against the Arizona Diamondbacks at 7:05 p.m. PT on Wednesday at PETCO Park. David Wells (5-7, 5.02 ERA) gets the start for San Diego. The D-backs will counter with Micah Owings (5-5, 5.13).
