Organization soon could have up to 10 second-generation players.
In the fifth inning of a spring training game against the Chicago White Sox in Glendale, Ariz., the Dodgers hit for the cycle as a team.
But this was not just any cycle: All four players were the sons of former big leaguers.
Tony Gwynn Jr. singled, Sellers doubled, Ivan DeJesus tripled and Scott Van Slyke homered.
"Oh, wow," Sellers said. "That is very unique."
Almost as amazing is the fact that the Dodgers have three other second-generation major league players in their organization: Dee Gordon, Matt Wallach and Jerry Hairston Jr. (Hairston is actually a third-generation player; his grandfather, Sam, spent most of his career in the Negro leagues before playing five games for the White Sox in 1951.)
The Dodgers haven't stopped there. In three days earlier this month they managed to draft three more sons of major-leaguers: shortstop Jesmuel Valentin (son of Jose Valentin), pitcher Jordan Hershiser (Orel) and shortstop Jose Vizcaino Jr. (Jose Sr.).
It has become common practice in recent years for major league teams to track and draft prospects with baseball in their genes, though not all make it this far.
Preston Mattingly, for example, was a first-round draft pick by the Dodgers in 2006 who was never invited to the team's major league camp. He signed a minor league contract with his father's former team, the New York Yankees, in January.
Considering that only 214 sons have followed their dads into the big leagues, it's no small feat that the Dodgers can count seven second-generation players in their organization.
Dodgers manager Don Mattingly said those seven have an advantage.
"To me, the biggest advantage is being around the clubhouse. They understand that guys are just regular guys," he said. "For me, growing up in Indiana, not really being around a major league city or major league teams, trying to go into a locker room with Goose Gossage, Graig Nettles, names like that - you kind of have this awe."
Some of those players can recall getting the awe out of the way early. Some can't. Here are their experiences:
Ivan DeJesus Jr.
The 24-year-old infielder, who made his major league debut with the Dodgers last April, is the only member of the seven who doesn't remember his father playing in the major leagues. That's because DeJesus was only 1 when Ivan DeJesus Sr. played his final major-league game as a Detroit Tiger.
But DeJesus Sr. went on to coach with the Houston Astros, and his son tagged along during summers, befriending the likes of Jeff Bagwell, Craig Biggio and Lance Berkman.
"I saw (Berkman) last year when I played against him in L.A., he was in St. Louis," the younger DeJesus said. "He said, `I'm getting old. I saw you when you were little.' I said no, everyone's getting old."
When your father, uncle, grandfather and brother were all professional baseball players, what's the plan if you don't ever reach the big leagues?
"That's a good question. I really don't know," he said. "Everyone says I can be argumentative at times ... maybe I'd make a pretty good lawyer."
Jerry Hairston Jr.
Hairston has carved out a pretty good career as a baseball journeyman; the Dodgers are his ninth team in 15 seasons. Last season with Milwaukee, he played five defensive positions and hit .274 with one home run in 124 at-bats.
At 35, Hairston is old enough to have played with Harold Baines (as a rookie in 1998 with the Orioles) and to have been an 8-year-old milling around the Chicago White Sox clubhouse when Baines was in his heyday.
"I knew that it was a big deal," he said, "but at the same time it's something that my dad did. When you came to the ballpark, it was something I always wanted to do."
Tom Gordon's 21-year major league pitching career ended in 2009, the same year his son was turning heads with the Dodgers' Single-A club.
This year, Dee Gordon is trying to make the leap from prized prospect to everyday shortstop and leadoff hitter.
More than a decade before he first set foot in the Dodgers' clubhouse, Gordon followed his dad into the clubhouse at Fenway Park. Back then, he was anything but nervous.
"I didn't grasp it then," Gordon said. "I was too busy playing basketball, running around. I was not in tune with baseball at that time."
That changed over time, of course, and Gordon brought plenty of butterflies to his first major league camp a year ago.
"Why wouldn't I be (nervous)? If I weren't, something would be wrong," he said.
Tony Gwynn Jr.
Tony Gwynn Sr., whose 3,141 hits rank 18th all-time, waited until his namesake son was 9 years old before bringing him to work one day, at Riverfront Stadium in Cincinnati.
"I knew none of my friends got to do that kind of stuff," the younger Gwynn said. "I was very aware of my surroundings, what I was doing. That's probably the reason why my dad allowed me to start going with him."
Taken in the second round of the 2003 draft by the Brewers, Gwynn Jr. debuted with Milwaukee three years later but didn't become an everyday player until 2009 with the Padres.
Though he felt comfortable from the outset, there was one thing Gwynn Jr.'s dad didn't teach him.
"I came here and ate what I wanted to, didn't have to think about it - not realizing my dad had to pay for both mouths in the clubhouse," he said.
Sellers, a 26-year-old infielder, played 36 games for the Dodgers in 2011 and made the big league roster out of camp. A bulging disk in his back has sidelined him since May 23.
His father, Jeff, is a Compton native and Paramount High alum who pitched for the Red Sox over parts of four seasons (1985-88).
"I remember talking to Jim Rice, I remember talking to Mike Greenwell," Justin Sellers said. "I was nervous. Those memories carry on to today. I never forget that stuff."
Those early experiences couldn't prepare him for his first major league game in Dodger Stadium last Aug. 12 - especially, he said, having grown up in Southern California. Sellers starred for Huntington Beach Marina before moving on to Cal State Fullerton.
"To really soak that up, words really can't explain the feeling that was running through my body the first time I got called up," Sellers said.
Scott Van Slyke
The Pittsburgh Pirates staged an annual father-son game when Andy Van Slyke was roaming the outfield, and Scott was a regular participant beginning at age 4.
Having toiled seven years in the Dodgers' system, the 25-year-old outfielder was called up to the big club May 10 after hitting .338 with eight homers and 25 RBIs at Triple-A Albuquerque. His first major league home run came 11 days later, and it was memorable - a decisive pinch-hit, three-run shot against another one of his father's old teams, the St. Louis Cardinals.
Perseverance alone might not have gotten Van Slyke - who was optioned to Albuquerque earlier this month - to the majors, but it has at least taught him a lesson.
"It's definitely your own experience," he said. "Coming here, being yourself is different. You know that you've worked hard, put in your years in the system."
Invited to spring camp as a non-roster player, Wallach was able to hang out with his dad in a major league clubhouse. Tim Wallach, a third baseman for three teams over 17 seasons, is now the Dodgers' third-base coach.
Matt Wallach was on the field for father-son games in Montreal at an early age, but it took a while for him to grasp their significance.
"Definitely when he was in L.A. (from 1993-96) when I was 8, 9, 10, you go and see you're around guys that you watch on TV," said Wallach, a catcher who is on the Dodgers' Double-A team in Chattanooga.
"Just being able to meet them and hang out with them was pretty awesome."
