The Tigers opened a three-game series in Baltimore on Monday night with a 4-1 win. Rick Porcello, now 6-and-1, has won five straight starts. Two of Porcello's six wins this year have come against the O's. Ian Kinsler went 2-for-3 with two runs scored and two RBIs, including his fourth home run of the year. Baltimore pitcher Bud Norris was ejected in the eighth inning after hitting Tori Hunter with a pitch. The two exchanged words on Hunter's way to first base, which drew both benches and bullpens to clear. No punches were thrown. The Tigers are 5 1/2 games ahead of the Royals for first place in the division. Drew Smyly on the mound tonight against Baltimore.
