CLEVELAND (AP) -- All Ubaldo Jimenez could do to try and shake off his slow start to the season was keep throwing strikes. It paid off against the Seattle Mariners .
The right-hander pitched six innings and the Cleveland Indians pounded out a season-best five doubles to beat the Mariners and ace Felix Hernandez 9-3 Wednesday night.
"This is the best Ubaldo has thrown the ball this year," manager Manny Acta said of the former All-Star, who has been wildly erratic since being acquired from Colorado for four players at the July trading deadline a year ago.
Hernandez (3-3) gave up 10 hits and six earned runs in only 3 2-3 innings. He and Jimenez combined for a 34-minute, 59-pitch first inning that ended with Cleveland ahead 4-1.
"Felix just had an off-day," Mariners manager Eric Wedge said of the 2010 AL Cy Young winner. "He's human. I think sometimes we forget about that."
Jimenez (4-3) gave up five hits and three runs over six innings. He threw 107 pitches - 27 in a long first inning - walked two and struck out four.
"I was able to attack the strike zone better," said Jimenez, who bounced back from giving up seven runs and walking five in only 4 1-3 innings in a loss five days ago in Boston.
"It's good to come back from a bad outing," Jimenez said. "It gives me more confidence."
Jimenez has worked with pitching coach Scott Radinsky to regain his form of early 2010, when he pitched a no-hitter and opened the year 15-1 for the Rockies. He has gone 18-23 since.
"It's all about mechanics and we've been working on it every single day," Jimenez said.
Travis Hafner hit his fifth homer and drove in three runs, while Shin-Soo Choo had three hits in Cleveland's third straight win.
Dustin Ackley had three hits, including a two-run homer, to extend his hitting streak to 12 games for Seattle, which dropped to 1-5 on a 10-game trip. The Mariners are 1-11 away from home since April 28.
Jimenez opened the game by yielding singles to Ackley and Michael Saunders , then uncorked a wild pitch that put runners at second and third. Ackley scored when Ichiro Suzuki grounded out.
"He did a very good job of getting out of that inning," Acta said. "He was in command the whole time, even after those first two guys got on. He threw 16 of 24 first-pitch strikes and looked relaxed."
Catcher Carlos Santana said he visited the mound early to make sure Jimenez did not tighten up.
"I told him something to make him laugh, then said keep the ball down and concentrate," Santana said. "He did."
Hernandez also gave up singles to the first two men he faced, Choo and Jason Kipnis . He then hit Asdrubal Cabrera with a pitch to load the bases.
Choo scored on a passed ball by catcher Jesus Montero , and Kipnis came home on Hafner's hard-hit ball that Ackley turned into a groundout with a diving stop and throw to first.
After Santana walked, he took off for second with two outs and Cabrera on third. Montero threw wildly past third, trying to get Cabrera leading off the bag. Cabrera scored and when left fielder Chone Figgins threw the ball back past Montero for another error, Santana also scored to make it 4-1.
The Mariners had gone 10 straight errorless games, one shy of the club record set Aug. 9-21, 1993.
Ackley's two-run homer, his third, got Seattle within 4-3 in the third.
Kipnis, Hafner and Santana all had RBI doubles in the fourth. Michael Brantley singled home Santana to make it 8-3.
It was the second consecutive rocky outing for Hernandez, who on April 19 struck out a season-high 12 in eight scoreless innings against Cleveland. On Friday, he allowed four runs and a season-high 11 hits over 6 2-3 innings in a 6-2 loss to the New York Yankees after giving up only four runs in his previous five starts combined.
