OAKLAND, Calif. (AP) -- Two of the American League's top teams have struggling closers who are accustomed to being among the best in baseball.
Joe Nathan held on through another rocky ninth inning for his 13th save a day after blowing one, and the Detroit Tigers beat the Oakland Athletics 5-4 on Thursday for a split of the four-game series between division leaders.
''If Joe's on you're going to have quick outs. He's been one of the best closers, he had an unbelievable year last year,'' Tigers manager Brad Ausmus said. ''If he's on, he'll get quick outs. It just wasn't today.''
On the other side, Oakland's Jim Johnson - the 2013 AL saves leader - walked off the mound to boos from the home crowd after allowing two runs in the seventh. He is pitching in lower-pressure situations for now.
''What am I supposed to do?'' he said of the crowd treatment. ''I don't know what to tell you. Balls are finding holes. I'm throwing pretty good pitches, I just feel like I'm in a little bit of bad luck. I don't think it's as bad as it really seems. I think everybody else thinks that way.''
Miguel Cabrera hit a go-ahead sacrifice fly in the fifth to back Rick Porcello's eighth victory.
Porcello (8-2) overcame a career-high six walks, three shy of his season total coming into Thursday's start. Nathan allowed Josh Donaldson's leadoff double, an RBI infield single by Yoenis Cespedes and Josh Reddick's run-scoring double before pinch-hitter Jed Lowrie grounded out to end the game.
It was Nathan's first outing since he surrendered Donaldson's game-ending three-run homer in Wednesday's 3-1 loss for his fourth blown save opportunity.
''You guys can get the guys that did their part. You can write whatever you want,'' Nathan said.
Victor Martinez doubled home two runs in the seventh and Cabrera also had an RBI groundout for the Tigers, who head to Seattle for the weekend before returning home.
Nick Punto hit a two-run homer in the fourth for Oakland, which wasted chances all game to lose for only the seventh time in 20 games.
Porcello moved into second place in the American League for wins behind Toronto's Mark Buehrle.
He did just enough this time, coming off his second loss of the year Saturday against Texas in which he was tagged for eight runs and 12 hits in 5 1-3 innings.
''It's no secret I was all over the place,'' Porcello said. ''I was fortunate to get out of some of the innings.''
Porcello improved to 5-1 on the road. He allowed five hits and two runs with four strikeouts in 5 2-3 innings.
Oakland starter Jesse Chavez (4-3) lost consecutive starts for the first time this season following a two-game winning streak.
His pitch count went up in a hurry. The right-hander walked two of his first three batters but escaped a rough first inning unscathed.
After Ian Kinsler lined out to start the game, Chavez walked the next two and received a mound visit from pitching coach Curt Young after going to 2-0 on cleanup hitter Victor Martinez. Martinez then singled and J.D. Martinez grounded into an inning-ending double play.
The A's left the bases loaded in the second and sixth innings, and also squandered scoring chances in the first, fifth and seventh. They had the tying run on second and go-ahead run on first to end the game, leaving 14 on base in all.
''We had plenty of opportunities,'' manager Bob Melvin said. ''We had some situational at-bats where we didn't come through.''
AL Central-leading Detroit, which eliminated the two-time defending AL West champion A's in a five-game division series each of the past two Octobers, won for just the third time in 11 games following a six-game winning streak.
