Nelson, 22, a 6-foot-7 left-hander, was 5-11 with a 4.87 earned-run average in 26 games with Detroit's single-A affiliate at Lakeland.
It was the first trade between the division foes in 10 years.
Second baseman Will Rhymes was sent to triple-A Toledo to make room on the roster for Young. Rhymes had been recalled Sunday.
RANGERS HONOUR LATE FAN
The Texas Rangers announced Monday plans for the creation of a statue that will honour Shannon Stone, a firefighter who fell to his death at a game last month.
The full-size bronze statue, tentatively to be named Rangers Fans, will depict Stone and his six-year-old son, Cooper, attending a Rangers game.
"We feel that this statue will be a most fitting tribute," Rangers CEO and president Nolan Ryan said. "It will not only serve to honour Mr. Stone's memory but also to recognize Rangers fans and baseball fans everywhere."
Stone fell from the stands July 7 during a game against Oakland. He was reaching for a foul ball thrown his way by Texas left fielder Josh Hamilton in the second inning.
The statue is expected to be in place by next season and likely will be located outside the home plate gate of Rangers Ballpark in Arlington.
"We continue to be appreciative of Nolan Ryan and the Texas Rangers as we deal with the loss of Shannon," Stone's widow, Jenny, said. "Shannon and Cooper had a special relationship, and we are touched and grateful that it will be memorialized at one of their favourite places.
"Our hope is that this statue will not be a symbol of our family tragedy but rather a reminder of the importance of a family's love -- love of each other, love of spending time together, and love of the game."
ASTROS LAND TEEN
The Houston Astros have acquired outfielder Domingo Santana from the Philadelphia Phillies to complete the July 30 trade for outfielder Hunter Pence.
Santana, 19 -- ranked as Philadelphia's No. 9 prospect by Baseball America -- was hitting .269 with seven homers in 96 games for single-A Lakewood this season. He will be assigned to Houston's affiliate in Lexington.
The Astros previously received outfielder Jonathan Singleton and pitchers Jarred Cosart and Josh Zeid in the deal. Singleton and Cosart had been considered the top prospects in the Phillies system.
PHILS BEAT THE BUSH
Former major-league starter Dave Bush has signed a minor-league deal with the Philadelphia Phillies.
Bush was 0-1 with a 5.79 earned-run average in 17 game with the Texas Rangers before being released July 6. He then signed a minor-league deal with the Chicago Cubs and made five starts for their triple-A affiliate in Iowa.
The 31-year-old right-hander has a career record of 56-69 with a 4.70 ERA in 210 games, including 187 starts, for Toronto, Milwaukee and Texas during his big-league career. He beat the Phillies in a 2008 NL division series while pitching for the Brewers.
Bush will report to Philadelphia's triple-A affiliate in Lehigh Valley.
NO RUBBER STAMP IN ASTROS SALE
The sale of the Astros to a group headed by Houston businessman Jim Crane will not get approval this week at owners meetings. The Houston Chronicle reports that MLB has concerns with Crane's past legal issues. The paper reported that in 1997 there were a series of Equal Employment Opportunity Commissioner complaints against one of Crane's companies, Eagle USA Airfreight, accusing it of discriminating against blacks and women.
There also have been charges of profiteering during the Iraq war. Crane's Eagle Global Logistics was sued four times by the Department of Justice, and in 2006, paid $4 million to settle a lawsuit brought by the Department of Justice accusing the company of inflating the costs of military shipments to Iraq.
Astros owner Drayton McLane reached an agreement to sell the club to Crane in May for a reported $680 million.
SOX RELEASE PITCHER
Pitcher Brian Bruney was released Monday by the Chicago White Sox.
The righty was designated for assignment Aug. 5 and had cleared waivers before rejecting an outright assignment to triple-A Charlotte.
He went 1-0 with a 6.86 earned-run average over 23 appearances out of the bullpen this season for Chicago.
Over eight seasons in the majors, he is 18-12 with a 4.70 ERA in 272 games with the Diamondbacks, Yankees, Nationals and White Sox.
