CLEVELAND - Max Scherzer didn't care that his record stayed spotless. All that mattered to him was that Detroit's improved.
Scherzer remained unbeaten and Victor Martinez hit a two-run double in the 10th inning as the Tigers extended their lead in the AL Central with a 4-2 win over the second-place Cleveland Indians on Monday night.
Martinez doubled off Matt Albers (2-1) as the Tigers won three of four in the series and moved 3 1/2 games ahead in the division.
Scherzer, attempting to become the first pitcher since Roger Clemens in 1986 to open a season 14-0, finished with a no-decision. He allowed two runs and seven hits in seven innings.
The presumed AL starter in next week's All-Star game will take his unblemished mark into a start on Saturday against Texas.
"I don't want to focus much on that (being 13-0)," he said. "This was our best win of the year, and I was proud to be a part of it. The Indians battled so hard tonight and brought their 'A' game, and we did, too.
"It was just a great team win, our best of the year."
Drew Smyly (4-0) worked out of a jam in the ninth and Joaquin Benoit pitched the 10th for his seventh save, striking out Mike Aviles with runners at first and third to end the game.
Matt Tuiasosopo homered for the Tigers, now 9-3 against the Indians.
Cleveland's Scott Kazmir went pitch for pitch with Scherzer, allowing just two runs and four hits in 5 2-3 innings.
Detroit was able to widen its lead over Cleveland by two games on this visit, but manager Jim Leyland knows champions aren't crowned in July.
"We came in and had a very good series against a very good team, but I'm not really concerned about the standings," Leyland said. "Of course, I'd rather leave here up 3 1/2 games than up 1 1/2 games. But trust me, the Indians are not going anywhere, and we're not going anywhere, I don't think."
