DETROIT – On another team, he might be an ace.

For the Detroit Tigers, Anibal Sanchez is the No. 3 starter — at least in this AL division series against Oakland.

Sanchez takes the mound Monday for Game 3 between the Tigers and Athletics after the teams split a pair of pulsating one-run games in Oakland. The A’s evened the series Saturday night despite a brilliant performance by Detroit right-hander Justin Verlander, and now the Tigers will call on Sanchez, another standout from what’s become an exceptional rotation.

“We just came back from playing two playoff games, and we’re pitching a guy that led the league in earned run average,” Detroit Manager Jim Leyland said. “That’s pretty good.”

Sanchez’s 2.57 ERA this season indeed paced the American League, and he’s been exactly what Detroit hoped for when the Tigers acquired him from the Miami Marlins last season. Sanchez, Verlander and right-hander Max Scherzer have been so good over the last couple years, it wasn’t clear how Leyland would order them for this series.

“This year, I just tried to keep to the level of those guys,” Sanchez said. “For me, I’ve got my job, and every five days, I try at that point, to throw a really good game.”

Scherzer won Game 1 against Oakland, and Verlander held the A’s scoreless for seven innings in Game 2. Oakland finally scored in the ninth off the Detroit bullpen to win 1-0, but now the Tigers can send Sanchez out Monday. Doug Fister will take the mound in Game 4 after going 14-9 with a 3.67 ERA during the regular season.

“They’re lucky enough to have three guys — and really Fister at times can be just as tough as any of them,” Oakland Manager Bob Melvin said. “If you put any of those four guys on a different team ... you’re looking at top-of-the-rotation guys.”

The A’s can run four solid starters too. Sonny Gray made an impression in his postseason debut Saturday, when he went toe to toe with Verlander. Oakland righty Jarrod Parker will pitch Game 3.

Detroit’s terrific rotation began coming together last year, when Scherzer shook off a poor start to become one of the AL’s best pitchers. The Tigers also traded for Sanchez, who looked like a solid, middle-of-the-rotation right-hander.

“We knew we were getting a guy that was going to keep you in the game, but he’s definitely been much better than I think anybody thought, as far as his consistency,” Detroit catcher Alex Avila said.

It’s been a tense, riveting start to this series — with a lot less scoring than the four-game set these teams played in Detroit in late August. The A’s scored 34 runs in that series and won three of four.

“Against these guys, you wouldn’t have expected that,” Melvin said. “But we just had a lot of momentum once we scored a bunch of runs the first game. We were getting pitch counts up, getting into the bullpen — a little different dynamic than what we’re looking at right now.”
