BALTIMORE (AP) It didn't matter to the Colorado Rockies that Chris Tillman was unbeatable at Camden Yards, where the Baltimore Orioles rarely lose regardless of who's on the mound.
On Tuesday night, the Rockies emphatically spoiled Tillman's bid to become the first 15-game winner in the majors.
Carlos Gonzalez and Trevor Story had two RBIs apiece in a four-run third inning, and the Rockies ended Baltimore's five-game winning streak with a 6-3 victory Tuesday night.
Tillman (14-3) gave up six runs and nine hits in five innings. The right-hander retired six of the first seven batters but needed 89 pitches to get 15 outs.
''We were patient,'' Gonzalez said. ''We had some really good at-bats against him. We know what kind of pitcher he is. He is having a tremendous year, especially here at his park.''
Tillman was 8-0 at home this season, and Baltimore was unbeaten in his 12 starts at Camden Yards. He permitted a combined four runs over 28 innings in his previous four starts, but in this outing Tillman tied a season high for runs allowed.
So what made this start so much different?
''I think the ball just fell where we weren't,'' he said.
After Colorado loaded the bases with one out in the third, Tillman retired Nolan Arenado on a foul popup and was within a strike of getting out of the jam when Gonzalez lined a double into the left-field corner. Story followed with a two-run single for a 4-0 lead.
''We had the two big at-bats with Cargo and Story. Both with two outs and two strikes,'' manager Walt Weiss said. ''Those two at-bats were crucial in the game.''
Arenado picked up his 78th RBI with a double in the fifth and came home on a wild pitch.
Adam Jones hit his 18th homer for Baltimore in the bottom half.
The Orioles still own baseball's best home record at 37-15, including 21-4 since the beginning of June.
Chad Bettis (9-6) won his third straight start, allowing two runs, four hits and three walks in six innings. Colorado is 8-1 in his last nine outings.
''They have a lot of guys who can slug it,'' the right-hander said. ''You just have to try to work in and out effectively. If you leave the ball up, stuff like the Jones' home run happens.''
Rookie Carlos Estevez got three outs for his ninth save.
The surging Rockies have won five of six and are 8-4 since the All-Star break.
''I've been telling the club all year I felt we were going to get better and better as the year goes on,'' Weiss said. ''That hasn't been our history the last few years.''
Orioles first baseman Chris Davis went 0 for 3 with two strikeouts and is 0 for 24 with four walks and one RBI since July 17.
''He's going through a period where he's not - stating the obvious - doing what he's capable of,'' manager Buck Showalter said. ''He'll get it going.''
Rockies rookie David Dahl finally got his luggage Tuesday, one day after making a cross-country journey to make his major league debut. He went 1 for 4 Monday night while wearing a glove provided by Mark Reynolds, swinging a bat donated by Daniel Descalso and running in cleats loaned by Story. Dahl started again Tuesday and went 1 for 4.
