Justin Masterson needed to make a great pitch. Nothing else would do.

The hottest team in baseball loaded the bases with two out in the first inning Monday night at Progressive Field. Jonny Gomes was at the plate with a 3-0 count and Masterson didn't have any idea where his pitches were going. Then, for whatever reason, Masterson's GPS locked in.

He threw three straight strikes and Gomes never took the bat off his shoulder. On the third and final called third strike, Gomes went to his knees in frustration and the Indians went on to beat Boston, 3-2, to end their seven-game winning streak.

"I got that strike out, going from 3-0 to 3-3, which was pretty nice," said Masterson. "Your confidence is at an all-time high after you're able to do something like that."

Asked what the pitch was, the Masterson couldn't help himself, "It was a reverse left-handed slider . . .No, it was a fastball. It almost seemed like it energized the guys. That in itself helped things out."

The Indians, propelled by Masterson's escape, scored early against John Lackey (6-4, 3.28) and hung on to stretch their winning streak to four games. Leadoff man Michael Bourn, who won Sunday's game with a walk-off two-run homer in the ninth, opened the first inning Monday with a walk and immediately stole second.

After Michael Brantley followed with a one-out walk, the runners advanced on Jason Kipnis' ground out to first. Lonnie Chisenhall blooped a single into left field for a 2-0 lead.

The Indians made it 3-0 in the third on Bourn's leadoff triple and Asdrubal Cabrera's single.
