Answer by taking a quote from the following article:

Ryan James Howard (born November 19, 1979) is an American professional baseball first baseman who is currently a free agent. Howard previously played for the Philadelphia Phillies of Major League Baseball (MLB) from 2004 to 2016. Howard stands 6 feet 4 inches (193 cm) and weighs 240 pounds (110 kg). He bats and throws left-handed.

On May 15, Howard recorded his first three-hit game, going 3-for-4 with a double, two singles, and a run-scored in a 4-3 win over the Cincinnati Reds. On July 3, Howard recorded his first three-RBI game against the Atlanta Braves. On August 23, he recorded his first four-hit game, going 4-for-5 with a double, a home run, two singles, three RBI and three runs-scored in a 10-2 win over the San Francisco Giants. On July 1, Howard became the Phillies' everyday first baseman when Thome was sidelined for the season with an elbow injury.  Howard was named National League (NL) Rookie of the Month in September. He batted .278 with 10 home runs and 22 runs batted in. In honor of winning the award, he received a specially-designed trophy.  Howard led all major league rookies with 22 home runs and posted a .288 average and 63 RBI in just 312 at-bats and 88 games. He hit 11 home runs and 27 RBI in September and October. Howard finished his rookie season with 17 doubles, two triples, 52 runs scored, and 100 strikeouts and 63 runs batted in as the Phillies battled the Houston Astros for the NL wild card until getting eliminated on the last day of the season. Howard was rewarded for his effort by being named NL Rookie of the Year, the fourth Phillie to win the award. He was also voted the Baseball Prospectus Internet Baseball Awards NL Rookie of the Year and received the NLBM Larry Doby Legacy Award (NL Rookie of the Year).  After the 2005 season, the Phillies faced a dilemma involving Thome and Howard. Both were very talented and proven power hitters; Thome was the biggest free agent player the Phillies signed prior to the 2003 season, but Howard was the reigning Rookie of the Year and a promising young player. Before the 2006 season, the Phillies traded Thome for outfielder Aaron Rowand and minor league pitching prospects Gio Gonzalez and Daniel Haigwood in order to make room for Howard.

What team did Thome then play for?
