The Diamondbacks have removed Zach Duke from the starting rotation.

Barry Enright will be called up from the minors to take his spot next Tuesday against the Brewers. Duke, 28, has an ugly 5.47 ERA over nine starts with the D-Backs this season. Not exactly what Kevin Towers was hoping for when he signed him this winter to a one-year, $4.25 million contract with an option for 2012.

Zach Duke allowed four runs on nine hits in six innings of work on Sunday, falling to 2-4 in Arizona's 4-2 loss to the Cardinals.

He struck out one and walked one, with his biggest mistake coming in the third, where he served up a two-run homer to David Freese. Through nine starts and 51 innings, Duke is the owner of a 5.47 ERA and 1.63 WHIP. That's no way to stay in a rotation long term.

Zach Duke didn't have it on Monday evening, getting battered for 13 hits and seven runs in just 4 2/3 innings of Arizona's 12-9 win over the Marlins.

His only real highlight came in the third inning, where he tagged Florida's Ricky Nolasco for a two-run homer, his second of the season. Coming into this evening, Duke had thrown up a 2.37 ERA and 1.21 WHIP in 19 innings over his first three starts. He is now the not-so-proud owner of a 4.56 ERA and 1.56 WHIP.

Zach Duke scattered nine hits and one run over seven innings of work against the Pirates on Wednesday evening, but got stuck with a no-decision against his former team, as Arizona would lose 3-2 in 12 innings.

Duke struck out one and walked zero, throwing 95 pitches in his seven frames. Through three starts and 19 innings, he is now 1-1 with a 2.37 ERA, 1.21 WHIP and 11/1 K/BB ratio. He'll get the Marlins in Florida his next time out.

Zach Duke lost after giving up four runs in five innings against the Nationals on Thursday.

That's a lot closer to what should be expected from Duke, who threw seven scoreless innings against the Astros in his season debut Saturday. He struck out six and walked none tonight, but the Nationals got to him for 10 hits.

Diamondbacks activated LHP Zach Duke from the 15-day disabled list.

Duke missed nearly the first two months of the season while recovering from a broken hand that he suffered in spring training. He was knocked around in his last rehab start for Triple-A Reno, but the D'Backs have decided that he's ready to go. He'll get the ball Saturday against the Astros.

Zach Duke (hand) is all set to make his Diamondbacks' debut Saturday.

Duke's season debut was delayed due to a broken hand suffered in spring training. He wasn't too effective in his most recent rehab start with Triple-A Reno, but the D'Backs evidently saw enough that they think the lefty is ready. He's got a nice matchup against the Astros, but we wouldn't recommend fantasy owners starting him right away.

Zach Duke (hand) allowed five runs over five innings Monday in a minor league rehab start with Triple-A Reno.

Duke gave up seven hits -- including two home runs -- while walking one and striking out two. Assuming the D-Backs were pleased with the outing, he could make his season debut Saturday against the Astros. The southpaw has been sidelined since the early part of spring training with a broken hand.

Zach Duke (hand) tossed five innings of one-run ball Wednesday in a rehab start at Single-A Visalia.

Duke also struck out four batters without issuing a walk. He's making a slow but steady recovery from a broken pitching hand and could return by the end of May.

Zach Duke will make his second rehab start Saturday since breaking his pitching hand on March 12.

Duke is essentially going through his spring training right now. He'll likely need at least two more rehab starts after today before getting back with the Diamondbacks.

Zach Duke (hand) will throw a simulated game Wednesday.

Duke broke his left hand when he was hit by a comebacker during spring training. He's making nice progress, but will likely need at least three minor league rehab starts before being activated from the disabled list. He only has an outside chance of pitching for the D-Backs this month.

Zach Duke (hand) threw a 30-pitch bullpen session Tuesday.

Duke broke his left hand when he was hit by a comebacker during spring training. He's scheduled to throw another bullpen session Thursday, but there's no clear timetable for his return. We're probably looking at a return by the end of May.

Zach Duke has begun playing catch for the first time since breaking his left hand in mid-March.

Duke will undergo an X-ray on his hand Sunday, at which point he'll have a better idea of a timetable for return. The D'Backs had said previously that he would likely miss 6-8 weeks, so a return sometime in May seems likely.

Diamondbacks placed LHP Zach Duke on the 15-day disabled list, retroactive to March 22, with a broken left hand.

Duke suffered the injury when he was struck by a comebacker earlier this month. He's expected to miss at least the first month of the season.

Diamondbacks general manager Kevin Towers said Zach Duke will likely miss 6-8 weeks with a broken left hand.

On Saturday, Duke was struck on the left hand by a line drive. He broke two bones in his pitching hand and won't throw for four weeks. Without Duke, there are two rotation spots to fight for between Armando Galarraga, Barry Enright and Aaron Heilman. Duke was acquired from the Pirates in November after going 8-15 with a 5.72 ERA and 1.65 WHIP over 29 starts last season.

Zach Duke is "very optimistic" that X-rays on his pitching hand will show that he didn't break anything when he was struck by a line drive Saturday.

"I can move my fingers," he said. "Obviously, there's discomfort. But I feel pretty good about it... They did some tests, some trainers' tests where they pushed on my knuckles and everything. I didn't have any sharp, shooting pains or anything. I'm very optimistic at this point." It sounds like he's probably avoided a serious injury, but we'll wait to see what the X-ray says.

Zach Duke left Saturday night's game against the Rockies after being hit on the left hand by a line drive.

He'll surely be taken in for X-rays. If it turns out that Duke has a break, then there'd be two rotation spots open for Armando Galarraga, Barry Enright and Aaron Heilman.

Zach Duke gave up three solo home runs in just three innings of work against the White Sox on Monday.

Not what Arizona wanted to see from a man that gave up 25 gopher balls in 29 starts last season. He's unlikely to have any fantasy value outside of very deep NL-only leagues.

Zack Duke allowed seven hits and three earned runs in a two-inning outing Wednesday against the Giants.

Duke walked one and didn't strike out anybody in his second outing of the spring. He allowed five hits and a run in a two-inning stint last week. Not a great first impression for the new Arizona starter.

Zach Duke reported to spring training on time after his wife gave birth to the couple's first child last week.

Diamondbacks general manager Kevin Towers previously thought Duke could be delayed, but the left-hander was right there with the rest of the pitchers and catchers. Duke was acquired from the Pirates in November after going 8-15 with a 5.72 ERA and 1.65 WHIP over 29 starts last season.
