The Chicago Cubs on Monday night traded left-handed pitcher Paul Maholm and outfielder Reed Johnson for two players from the Atlanta Braves.
Coming to Chicago are right-handed pitchers Arodys Vizcaino and Jaye Chapman.
Vizcaino, 21, is a top prospect who had season-ending Tommy John surgery in April. He will miss the 2012 season, but is expected to be ready for 2013 spring training.
Chapman, 25, has struck out 60 batters and allowed only three home runs in 53.2 innings.
Earlier, fans saw catcher Geovany Soto and Johnson hugging teammates in the dugout after being pulled from Monday night's game, fueling speculation they had been traded.
Cubs manager Dale Sveum said he'd been told to take them out, but offered no other details. Johnson's trade was later confirmed.
Soto is reportedly heading for the Texas Rangers. In turn, Texas' Jacob Brigham will come to Chicago, according to several reports.
Tuesday afternoon is the deadline for teams to make trades without waivers. Cubs ace Ryan Dempster has attracted interest from several clubs.
