Chris Waters (1-0, 4.50) vs. 
Nate Robertson (7-8, 5.84)
With their newly shuffled lineup, the Tigers welcome another below-.500 team to Comerica Park for a three-game weekend series. Detroit's post-All-Star break schedule got off to a disappointing start when they split a four-game series with the Orioles, and that probably should've given us an indication about how the rest of this season might go.
Chris Waters makes just his third start of the season for Baltimore, and this might be sort of a rubber match for him. In his first outing, Waters was outstanding against the Angels in Anaheim, giving up just one hit over eight innings. Next time out, however, he was shelled for six runs and seven hits by the Indians in just four innings at home. So what will we see tonight from him?
For that matter, which Nate Robertson will the Tigers get this evening? Against Oakland last Sunday, he was pretty close to great, allowing just one run and five hits over 7 2/3 innings. But that was against the Oakland A's. About a month ago in Baltimore, Robertson got rocked for seven runs in just 2 1/3 innings, arguably his worst game of the season. At home, however, he has a winning record and his ERA is about three-and-a-half runs better.
