The Diamondbacks and Rockies continue their four-game series Saturday night at Coors Field.
With nine wins in its last 14 games, Arizona (75-75) is 4 1/2 games behind St. Louis for the second wild card. Milwaukee, the Los Angeles Dodgers and Philadelphia are also in front of the Diamondbacks.
Trying to keep pace, Arizona won 15-5 Friday to improve to 7-5 in the season series against Colorado, which it will face six more times. The Diamondbacks, who have averaged 6.1 runs in the 12 games, have won five of the last six meetings.
“We haven’t had one of these in a while, so it felt good,” manager Kirk Gibson said. “Contributions from everybody.”
Eaton’s home run was his second in as many days. He’s hitting .273 with 13 runs scored and 11 walks in 14 games since being called up earlier this month.
He’ll try to help Arizona continue to take advantage of its matchups against Colorado (58-92), which has lost seven straight and 14 of 16. The Rockies have allowed at least 12 hits in four straight games and have a 7.87 ERA over their last 10.
Trying to stabilize things, Colorado will hand the ball to Jhoulys Chacin (2-5, 4.58 ERA), who has a 2.37 ERA in six starts since returning from the disabled list last month.
Chacin allowed one run over five innings of a 2-1 loss to San Francisco on Monday.
“I just want to keep feeling good, be healthy and finish the season strong,” said Chacin, who spent three-plus months on the disabled list with right shoulder inflammation.
The right-hander is 3-2 with a 2.76 ERA in eight appearances - seven starts - versus Arizona, striking out 44 in 42 1-3 innings.
Patrick Corbin (6-7, 4.02) will counter for the Diamondbacks as he looks to build on one of his best outings of the season.
Corbin gave up two runs over a season-high eight innings of a 10-2 win against the Giants on Sunday.
The rookie left-hander had never pitched longer than seven innings, had an RBI or had an extra-base hit, but accomplished all three - driving in four - in the victory.
“As you guys remember, he’s had games where he has had low pitch counts and then as soon as he hit the seventh inning he was done,” Gibson told the Diamondbacks’ official website. “It’s good to see him get additional innings and make a step forward.”
Corbin had a much rougher outing in Denver on May 14. He surrendered six runs and nine hits over six innings of a 6-1 loss.
