The Diamondbacks appear to have gotten the better of the deal.
Hudson will try to extend his surge Friday night as Arizona opens a three-game weekend set against Jackson and the White Sox in Phoenix.
Arizona had the second-worst record in the NL last year when they shipped Jackson, who threw a no-hitter earlier in the season, to Chicago for Hudson, who had a 4.72 ERA in nine games over two seasons.
Since the deal, Hudson has gone 14-6 with a 2.83 ERA in 25 starts with Arizona going 16-9. Jackson has posted an 8-7 record with a 3.83 ERA as Chicago has split his 24 starts. Hudson (7-5, 3.82 ERA) also is averaging 8.2 strikeouts per nine innings compared to Jackson’s 7.9.
After getting off to an 0-4 start in 2011 for Arizona, Hudson has turned things around by going 7-1 with a 3.06 ERA in 10 games. He gave up one run and eight hits in six innings of the Diamondbacks’ 5-1 win over Florida on Sunday.
Jackson (4-5, 4.39) opened with back-to-back victories this year, but success has been limited after that. Over his last three starts, the right-hander has no record and an ERA approaching 5.00.
Against Oakland last Friday, he surrendered two runs in six innings before the White Sox allowed four in the ninth and lost 7-5.
Manager Ozzie Guillen told the White Sox’s official website that a big challenge awaits his team at Chase Field.
“We’re going for business - tough business - the Diamondbacks are playing very well. They have a good ballclub, and we have to be aware of that,” he said.
Arizona (38-32) drew within 1 1/2 games of NL West-best San Francisco with a 3-2 win in 10 innings over the Giants on Thursday. Chris Young hit a two-run shot in the fourth inning before Justin Upton’s(notes) first career walk-off homer capped a three-hit night.
“It’s awesome,” Upton said. “The fact that we’d just dropped two games and to be able to win in that fashion. It’s hopefully a little bit of a boost for the team.”
Young and Upton have been Arizona’s hottest players this month. In 15 games, Young is hitting .345 with five homers and eight RBIs while Upton is batting .379 with a homer and seven RBIs.
The Diamondbacks have homered in eight straight games, and lead the NL with 82. The White Sox, meanwhile, are tied for eighth in the AL with 58 homers allowed.
Chicago (33-37), which fell 1-0 to Minnesota on Thursday, managed one run and hit into six double plays while being swept in the rain-shortened two-game series.
“Obviously he’s not a Gold Glover, but he’s going out there and he knows what to do,” Guillen said of 6-foot-6, 287-pound Dunn, who played 44 games with Arizona following a trade from Cincinnati in 2008.
The White Sox have not visited the Diamondbacks since June 3-5, 2003. Arizona has won four of six all-time meetings.
