2004 season

After being called up from the Triple-A Nashville Sounds to replace Raúl Mondesí, Ward got off to a torrid start. On May 26, 2004, Ward, recalled from the Triple-A Nashville Sounds two weeks before, hit for the cycle and tied his career high with six RBI in the Pirates' 11–8 victory over the St. Louis Cardinals. Ward hit a two-run double in the first, an RBI triple in the fourth, golfed a three-run homer in the fifth and singled in the ninth. He was the first Pittsburgh player to hit for the cycle since Jason Kendall on May 19, 2000, against the Cardinals. Ward joined his father, Gary, to become the first father-son combination in major league history to hit for the cycle. The elder Ward accomplished the feat on September 18, 1980, for the Minnesota Twins. (They were later joined by Craig and Cavan Biggio on September 17, 2019 as the only 2 father and son duos to hit for the cycle in MLB history.) Ward slumped later in the season, slowed down by a wrist injury, and finished hitting .249 with 15 home runs and 57 RBI, with a .306 OBP and .474 SLG. Ward, along with Valerio de los Santos, signed a deal to play with the Nationals.

2006 season

On August 31, 2006, Ward was traded to the Atlanta Braves for minor-league pitcher Luis Atilano.

2007 season

Ward was signed on December 7, 2006 by the Chicago Cubs to a one-year deal worth $1.05 million after hitting .308 with a .380 OBP in 2006 for Washington and Atlanta in 150 combined plate appearances. He replaced John Mabry as a backup at 1st base to Derrek Lee. On May 6, Ward hit a game-winning single against his former team, the Washington Nationals. He was also called to replace Derrek Lee on May 13, after Lee left the game with neck spasms. Ward also saw time as a pinch hitter in close game situations. On August 18 Ward hit a grand slam in the third inning off of St. Louis Cardinals pitcher Anthony Reyes, the third of his career and his first home run as a member of the Cubs. Ward finished the season with a career-high .327 batting average in 110 at-bats.

2008 season

On August 15, Ward launched a three-run pinch-hit homer with one out in the ninth inning to lift the Cubs to a 6–5 victory over the Florida Marlins for their ninth straight road win. The Cubs had lost their last 10 games at that stadium. He became a free agent at the end of the season. Ward finished the season with a .216 batting average, the second lowest of his career.
