Duke, Borchering power Rawhide

After losing five of their last six games, the Visalia Rawhide got a little big league help on Wednesday afternoon. It turned out that they didn't need it.

Major League veteran Zach Duke pitched five solid frames, first baseman Bobby Borchering drove in a career-high five runs and outfielder Adam Eaton fell a double shy of the cycle as the Rawhide ripped the visiting Rancho Cucamonga Quakes, 10-2.

Duke, who went 45-70 with a 4.54 ERA over six seasons with the Pittsburgh Pirates, suffered a broken pitching hand when he was struck by a comebacker in a Spring Training game March 12. Wednesday's outing for the Class A Advanced affiliate was his first official game in the Diamondbacks organization since being acquired in a trade in November.

The left-hander got off to a rocky start at Rancho Cucamonga, yielding singles to the first three batters he faced. Duke induced a double-play ball from Quakes cleanup hitter Tony Delmonico, allowing a run to score, then fanned Blake Smith to escape serious damage.

Duke (1-0) allowed a one-out single in the second and a one-out double in the fifth before giving way to the Rawhide bullpen. He was charged with one run on five hits, striking out four and without walking a batter, over five innings.

The 28-year-old departed with a comfortable 5-1 lead with the help of Eaton, who went 4-for-5 with a homer, a triple, three runs scored and two RBIs. The 22-year-old outfielder raised his batting average to .395, second-best in the Cal League. He leads the circuit with a .500 on-base percentage.

Eaton, a 19th-round pick in the 2010 Draft, opened the scoring with a two-out blast in the first. He singled in the third, tripled and scored in the fifth, grounded out in the seventh and singled again in the ninth.

After an RBI single in the third, Borchering struck the biggest blow of the game in the ninth, blasting a one-out grand slam to cap a five-run frame. A first-round pick in 2009, the switch-hitter had never driven in more than three runs in a game before.

Catcher Mark Reed singled four times in five at-bats and is 6-for-10 in his last two games after going 0-for-14 in his previous four.

The Quakes collected 11 hits, but did not notch an RBI. Catcher Gorman Erickson tripled and scored on a wild pitch in the seventh inning.

Rancho Cucamonga starter Ethan Martin fell to 3-2 after allowing five runs -- three earned -- on eight hits over six frames.
