The Houston Astros have acquired David Paulino from the Detroit Tigers as the player to be named later in the July trade involving Jose Veras.

Paulino, 19, made four starts for Detroit's Rookie-level Gulf Coast League affiliate this season and was impressive.

The Dominican native allowed six runs in 20 innings for a 2.70 ERA with an impressive 22-to-2 K/BB ratio.

The Yankees have acquired infielder Brendan Ryan from the Mariners for a player to be named later, according to an ESPN.com report late Tuesday night.

The move could mean the Yankees feel Derek Jeter may not return to the lineup anytime soon.

Ryan, a superior fielder with a weak bat, hit just .192 in 87 games for the Mariners this season, with three home runs and 21 RBIs.

The Philadelphia Phillies acquired Rob Rasmussen from the Los Angeles Dodgers in exchange for Michael Young over the weekend.

The left-hander was a second round pick of the Miami Marlins back in 2010. The Phillies also sent cash to the Dodgers in the trade.

"Rasmussen is a smaller lefty with a big arm," Ruben Amaro said. "He's starting now, but he could be a guy later on who could pitch in the bullpen. Lefthanders are always valuable. He's viewed as a really strong makeup kid with a big arm."

The player to be named later in the trade that sent Justin Morneau to the Pittsburgh Pirates will be Duke Welker, according to a source.

The Minnesota Twins also received outfielder Alex Presley in the deal.

Welker, 27, made just two appearances for Pittsburgh this season (1.1 innings).

The Dodgers acquired veteran infielder Michael Young from the Phillies in exchange for a minor-league pitcher, the teams announced Saturday night.

The Dodgers plan on using Young as a bench player who can spell third baseman Juan Uribe and first baseman Adrian Gonzalez, as well as pinch hit.
