The Tigers scored one run in both the eighth and ninth innings on two-out doubles against the Orioles bullpen, and Tigers closer Fernando Rodney pitched a scoreless ninth for his 10th save.
"We'll take those kinds of outings from our starters all the time," Orioles manager Dave Trembley said. Berken "pitched very well. Just so happened that Jackson pitched a little bit better."
Jackson, 25, entered the afternoon with a 2.58 ERA on the season but an 8.31 mark against the Orioles in five previous games - all with the Rays. In those outings, Jackson allowed 16 earned runs and a staggering 36 base runners in 17 1/3 innings.
Sunday, he didn't give up a hit until Nick Markakis' fourth-inning single. In the sixth, he hit Robert Andino with a pitch, but Andino was promptly thrown out attempting to steal second.
Ty Wigginton led off the eighth with a double but was stranded when Jackson induced a lineout and two groundouts.
It ended the Orioles' hopes of winning a second consecutive series. But it didn't dampen their positive vibes about the past week - and, potentially, the future.
"A lot of progress, very good enthusiasm on the club and with our fans," Trembley said summing up the week. "Up-tempo-type games, much cleaner-type games and a whole lot more fun to play. A whole lot more fun."
