OAKLAND, Calif. -- On a day when his fastball didnt have much bite and his breaking pitches were flat, Jesse Chavez finally got the victory that had eluded him through the first two weeks of the season. The 30-year-old starter also managed to carve a spot in the Athletics history books along the way. Chavez combined with three relievers on a five-hitter, and Josh Donaldson drove in three runs to help Oakland beat the Houston Astros 4-1 on Sunday to complete a series sweep. "Today was one of those days where I had to make pitches and see pretty much what I was made of as a starter," said Chavez after lowering his team-leading ERA to 1.38. "The only thing I had pretty much working today was my changeup. That was a good pitch that I needed." Chavez (1-0) allowed four hits over six innings and retired seven of the final eight batters he faced after giving up a solo home run to Marwin Gonzalez in the fourth. He struck out three, walked one and became the first pitcher in franchise history to be on the opening- day roster and allow one earned run or less in six innings during each of his first four starts. Not bad for a guy who was on the fringe of the As rotation until injuries sidelined Jarrod Parker and A.J. Griffin. "I think hell tell you he struggled with his command moreso today than any other day," Oakland manager Bob Melvin said. "Thats really the mark of a good pitcher, when you dont have your best stuff. Hes been focused and ready for that opportunity and continues to run with it." Josh Donaldson homered and doubled twice while Jed Lowrie and Eric Sogard added two hits apiece for the As, who have won 11 of 13. Oakland has the best record in the American League despite a shaky defence that committed its AL-leading 19th error. Gonzalez had two hits for the Astros. Houston has dropped seven straight. "We have an underperforming team right now, and when you underperform and make the mistakes that we make this is going to be the result," manager Bo Porter said. Donaldson hit a two-run homer off Houston starter Brad Peacock in the first and added an RBI double in the seventh. He also had a two-out double in the fifth. That helped offset an early miscue by Oaklands third baseman. Donaldson bobbled George Springers grounder in the third, extending the teams worst defensive stretch since 2011. Lowrie, the shortstop, also dropped a high popup by Springer in the eighth, marking four straight games in which the As have committed at least two errors. Overall, Oakland has made an error in nine consecutive games. "I dont like it," Melvin said. "You cant continually play defence like this and get away with it." Three of Houstons first four batters reached base before Oaklands young right-hander settled down. After catcher John Jaso threw out Jose Altuve trying to steal third, Chavez got Marc Krauss to fly out. The Astros also had two runners on with two outs in the third following Donaldsons fielding error but Chavez retired Krauss on a deep fly to right. Houston managed just one baserunner against Chavez after that, a one-out walk to Dexter Fowler in the fifth. Jim Johnson, still trying to win back the As closer spot, replaced Chavez to start the seventh and retired the first two batters before walking Altuve. After Fowler reached when his sharp comebacker deflected off Johnson, reliever Sean Doolittle came in and got Jason Castro to fly out to left. Luke Gregerson pitched the ninth for his third save. Donaldsons two-run home run off Peacock (0-2) in the first put the As up 2-0. Lowrie singled with one out before Donaldson hit the 3-1 pitch to left. Gonzalez, who singled off Chavez in the second, hit a two-out home run in the fourth to cut it to 2-1. Donaldson doubled in Coco Crisp in the seventh and Lowrie scored on a passed ball in the same inning. Peacock struck out four and walked three in his first start of the season. The former Oakland prospect, who began the year in Houstons bullpen, allowed five hits over five innings.

DETROIT -- The Kansas City Royals finally lost, but slugger Billy Butler hopes their impressive push in the AL Central will go on. "This doesnt end anything," he said. "Weve got 10-1 in our last 11 games, and were going home in first place. We just have to keep playing the way we are right now." Anibal Sanchez pitched seven sharp innings, and the Detroit Tigers snapped Kansas Citys 10-game winning streak with a 2-1 victory Thursday. J.D. Martinez hit a tiebreaking homer in the fourth for the Tigers, who avoided a four-game sweep and pulled within a half-game of the AL Central-leading Royals. Sanchez (4-2) allowed five hits and a walk, keeping the Kansas City offence quiet even though he failed to strike out a batter. Joba Chamberlain pitched the eighth, and struggling closer Joe Nathan struck out the side in the ninth for his 14th save in 18 chances. Danny Duffy (4-6) allowed two runs and three hits in seven innings. He walked one and struck out five. "We just had a great road trip, Danny Duffy just pitched a great game, and we lost a game to a great pitcher and a home run where I have no idea how J.D. Martinez hit the ball out of the park," Royals manager Ned Yost said. "All I can do is tip my cap to him, because he killed us all series." Butler gave the Royals a 1-0 lead with an RBI double in the first, but Miguel Cabrera drove in a run with a double of his own in the fourth. Cabrera was tagged out on a bizarre double play when right fielder Nori Aoki caught Victor Martinezs flyball and threw back to the infield, where Cabrera was nonchalantly returning to second. Shortstop Alcides Escobar caught the ball and made the tag. Cabrera was initially ruled safe, but the call was overturned on replay. J.D. Martinez followed with a solo homer to right, his sixth of the year. He now has a nine-game hitting streak, with a .412 averagge in that span, and he hopes this win will end a stretch in which so much has gone badly for the Tigers.dddddddddddd. Detroit won for only the 10th time in its last 30 games. "Its funny, even talking to the umpires, they even chime in and say it. Theyre like, Dude, everything thats going wrong just seems to be going wrong for you guys. You guys just got to grind through it," Martinez said. "You see the breaks that weve been getting. We hit the ball hard, it gets caught. We hit it soft, it gets caught. We get on base, the ball goes to the backstop, comes back, gets thrown out, were out of an inning. Its just kind of like, craziness." Sanchez went without a strikeout for the first time in his career, but his fielders helped him. Third baseman Nick Castellanos reached over the railing of the Detroit dugout to catch a foul popup in the sixth. Nathan, who signed with the Tigers in the off-season, brought a 6.57 ERA into the game. He struck out Butler to start the ninth -- the Kansas City designated hitter argued the called third strike -- and Salvador Perez went down swinging. With the crowd on its feet and anxious for a much-needed win, Nathan struck out Lorenzo Cain to end it. "That looked like the Joe Nathan Ive faced for years," Butler said. "All those times with the Twins and then with Texas -- the one with a few hundred saves and all those All-Star games. Hes had some tough moments in his career, but that looked like the same guy today." The Royals were without outfielder Alex Gordon, who sat out because of flu-like symptoms. Detroit outfielder Torii Hunter (hamstring) did not play either. NOTES: The Tigers play at Cleveland on Friday night. Detroit RHP Rick Porcello (8-4) faces Cleveland RHP Corey Kluber (6-4). ...
