The Baltimore Orioles broke out with their most productive inning at the plate this season to end their losing streak, though they could have a difficult time building on that effort against one of baseball's hottest pitchers.
Adam Jones ended a 1-for-18 slump with three hits and Manny Machado stayed hot with two and two RBIs as Baltimore (66-56) scored seven runs in the third inning and snapped its four-game skid with an 8-4 victory Saturday.
"I think people panic a little more outside the clubhouse than we do inside the clubhouse,'' said Brian Roberts, who had a two-run double in the third. "We all still feel like we are in pretty good shape.''
Although Machado has gone 7 for 15 in his last three games, the Orioles had hit .226 during their longest losing streak since June 21-24.
They aren't likely to have it easy as they face the red-hot Chacin (11-6, 3.18 ERA). The right-hander is 8-3 in his last 12 starts, with his 2.05 ERA over that span ranking among the lowest in the majors.
He'll try to help Colorado (58-66) win an interleague series on the road for the first time since taking two of three in Cleveland from June 20-22, 2011. The Rockies have dropped 13 of 18 in those contests since that set.
After getting a total of 13 runs from his offense over his previous six starts, Chacin received a career-best 14 from the Rockies in a 14-2 win over San Diego on Monday. He struck out six while giving up one run and five hits over eight innings.
"I think the key is I'm throwing my sinker for a strike, getting down and have to make them swing the bat," Chacin told the league's official website. "So that's what I'm pretty much doing, just throw my fastball for a strike, and then trying to mix in my breaking balls and my changeups."
Chacin has been especially tough on the road, where he's 4-3 with a 1.87 ERA in nine starts. He hasn't yielded a home run in his last eight away from home.
Chacin might not have to deal with J.J. Hardy after the Orioles shortstop was a late scratch Saturday with back spasms.
Baltimore hopes to win for the third time in eight games as it counters with Scott Feldman (2-3, 5.18), who has gone 0-2 with a 6.00 ERA in his last three starts - all Oriole losses.
Feldman, though, showed some improvement in his last outing, fanning eight and allowing two runs - one earned - over 5 1-3 innings before Arizona rallied late for a 7-6 victory Monday.
Feldman has been knocked around at Camden Yards since joining the Orioles, going 1-3 with a 7.66 ERA in four starts. He hasn't faced the Rockies since making two relief appearances against them in 2006.
Former Twin Michael Cuddyer has fared well against the right-hander, going 7 for 13 with two homers and three doubles in this matchup. He's also hitting .336 in 33 career games at Camden Yards.
Teammate Wilin Rosario went 2 for 5 Saturday and is batting .385 with 11 RBIs during a nine-game hitting streak, while Dexter Fowler is 9 for 20 with six RBIs over his last five games.
The Rockies have been on a roll offensively, averaging 6.5 runs and hitting .316 over their last eight contests.
