Rick Porcello's start to the season, the best opening month and a half of his career, began against the Orioles.
Baltimore will get another crack at the Detroit right-hander on Monday at Camden Yards for the start of a three-game set. The Orioles dropped two of three to the Tigers when they met at Comerica Park in the second series of the season.
Just like the April 5 meeting, Porcello will be opposed by Bud Norris, who would rather forget that game. Norris allowed nine hits and five runs in five innings of work.
"Everyone knows what this team can do," Norris said after the loss. "You make a mistake against those guys, and you pay for it."
Porcello has been instrumental in the Detroit rotation's status as the best in the American League. He's tied with reigning AL Cy Young Award winner Max Scherzer for the team lead with five wins. Porcello will have his hands full, though, with Baltimore slugger Chris Davis.
Davis returned to the lineup Sunday after a strained left oblique sidelined him for 15 days.
"I don't have any pain or discomfort," Davis said Sunday. "I don't have any stiffness, which I was kind of wondering whether I was going to be tight or stiff or anything like that."
Davis said the team's performance made it easier for him to be away for a couple of weeks. Both the Tigers and the Orioles enter the series in first place in their respective divisions.
Tigers: Rotation key to recent success
Manager Brad Ausmus had to think long and hard about when the last time one of his starting pitchers didn't do, at the very least, an adequate job.
And his answer showed just how strong the rotation has been over this recent stretch.
"The last bad start was when Anibal Sanchez had to come out of the game in the third [because of an injury]," Ausmus said before Sunday's game, referring to Sanchez's injury on April 26.
Detroit starters lead the AL with a 2.81 ERA entering play Sunday. Opponents were hitting just .227 against the rotation.
Orioles: Wieters heads to DL
The Orioles got a boost of good news in the return of Davis on Sunday, but they lost All-Star catcher Matt Wieters to the disabled list with no certainty on his return.
Wieters has been limited to designated hitter duty due to right elbow discomfort, and he will now get a few weeks of rest before the club re-evaluates and determines the next step.
"We'll take a two or three week period to see if we can get it managed and then see if he can catch the rest of the year. Or if he's still having problems with it at the six-week mark we will have to think about something else," manager Buck Showalter said of Wieters, who had his elbow examined by Dr. James Andrews on Wednesday. "That's as frank as I can be about it. That's where we are with it."
The organization is still hoping Wieters can avoid surgery with rest, with both the team's doctors and Andrews concurring that surgery isn't inevitable but is a possibility if the discomfort can't be managed with rest and treatment.
