OAKLAND — A look of despair ran across Tigers outfielder Akil Baddoo’s face as he watched a 96.2-mph sinker paint the inside corner for strike three to begin the third inning. That’s just the type of uncomfortable body language that Frankie Montas tends to produce from opposing hitters when he’s at his best.

In two of his three starts this season, Montas’ electric arm has caused plenty of hitters to squirm in the batter’s box. That includes his brilliant outing in Friday’s 3-0 A’s win over the Tigers, in which he tossed six scoreless innings of two-hit ball with seven strikeouts and one walk to help extend Oakland’s American League-best winning streak to six games.

A rough outing to start the year against the Dodgers has ballooned Montas’ ERA to 4.91. However, in his last two outings, the right-hander has allowed just one run with 12 strikeouts and two walks in 12 innings, looking more like the dominant arm that the A’s still believe he can morph into.
