Robertson (7-8, 5.84 ERA) lost his first career start against the Orioles on April 19, 2005, but is since 4-0 with a 3.32 ERA in seven starts against them. In his only start against them this season on July 19, however, he was tagged for seven runs in a season-low 2 1-3 innings in a 11-10 loss in 10 innings.
The southpaw won for the first time in eight starts Sunday by yielding one run over 7 2-3 innings in a 6-1 victory over Oakland. Robertson was 0-2 with an 8.42 ERA over his previous seven outings.
“There’s plenty of games that I pitched well,” Robertson said. “I just tried to go out and pitch well again. That’s it.”
Detroit (59-62) is 9 1/2 games behind the first-place Chicago White Sox in the AL Central after being expected to contend for the title. The Tigers have lost 10 of their last 14 games, but insist they will play hard for the rest of the season.
“We’ve got a lot of pride here. I just wanted to make sure we didn’t get lulled to sleep,” Tigers manager Jim Leyland said. “You can’t always have a good performance but you can come here and play hard.”
Edgar Renteria went 2-for-4 on Thursday when Detroit salvaged the finale of a four-game home series with Toronto with a 5-1 victory. Renteria is 9-for-21 (.429) in the first seven games of this 10-game homestand.
Detroit’s lineup will get its first look at Baltimore rookie Chris Waters (1-0, 4.50), who was spectacular in winning his debut before he was hit hard in his last outing. Waters allowed one hit in eight innings on Aug. 5 in a 3-0 victory over the Los Angeles Angels in his first major league appearance.
The left-hander had a much different outcome in his outing Sunday against Texas as he gave up six runs over four innings in a 15-7 loss.
“Waters was a different pitcher today. His location was up,” Orioles manager Dave Trembley said.
Baltimore (58-62) is making its only trip this season to Comerica Park, where it was swept in a three-game set in its lone visit in 2007. The Orioles and Tigers split four games at Camden Yards from July 17-20.
Nick Markakis went 9-for-17 with eight RBIs in the series for the Orioles, who have scored 55 runs in their last seven games.
