CLEVELAND — An earthquake shook the upper levels at Progressive Field on Tuesday, but the Indians stood still.

Despite winning the first game of a doubleheader against the Mariners in dramatic fashion, 7-5, the Indians wound up breaking even on the day, dropping the nightcap, 12-7.

“It was a long day just to get a split,” said Cleveland manager Manny Acta, whose club has dropped five of its last six games. “It’s disappointing.”

Cleveland did move a bit in the Central Division standings — the wrong way — falling six games behind the first-place Tigers, who won at Tampa Bay. It is the largest deficit of the season for the Indians, who with a White Sox victory at Los Angeles on Tuesday night, would begin today in third place.

“I’m not counting myself,” Acta said of the deficit. “I’m just trying to win games. Wake me up when we’re mathematically eliminated, if we’re not in first place.”

The Indians were unable to ride the momentum from a fantastic finish in Game 1, which they won on a three-run walk-off home run from Shin-Soo Choo.

They needed the heroics from Choo thanks to another rough outing from closer Chris Perez, who blew the save a night after taking the loss in another shoddy ninth-inning effort.

Choo also saved Justin Masterson from another tough-luck loss. Masterson owned a one-run lead as he took the mound for the ninth inning and a complete-game bid.

He got an out but put two on for Perez, who had little time to warm in the bullpen before allowing the tying and go-ahead runs to cross the plate on a double from Trayvon Robinson — the first batter he faced.

“It’s not the easiest situation, but that’s my job,” Perez said. “I felt fine. If I wasn’t ready, I would have told them I wasn’t ready.”

Masterson wasn’t as good as he has been for much of the year, allowing five runs on on 10 hits, while striking out seven over 8 1/3 innings. But he gave the Indians a chance to win, as he has done nearly every time he has taken the mound this year.

“He hasn’t had a rough spot the whole year,” Acta said. “He’s been so dominant. We feel at the end of the game that he’s earned the right to finish it.”

Conversely, Perez has hit another rough patch as of late.

“He’s getting himself into hitter’s counts,” Acta said.

Ironically enough, Choo’s double in the third inning arrived at the same time as the quake that swayed the press box and could be felt in the upper deck. Little if any of the players on the field were aware that it hit.

For all practical purposes, the nightcap was over much faster.

The Indians took a 1-0 lead in the first on an RBI double from Kosuke Fukudome, then watched the Mariners steamroll starting pitcher Zach McAllister, who was called up from Triple-A Columbus to make his second spot start of the season on the big league level.

After working two scoreless innings, McAllister unraveled, allowing five runs apiece in the third and fourth, with Seattle building an insurmountable 10-2 lead after 3 1/2 innings.

“The kid couldn’t pitch ahead,” Acta said. “He couldn’t make quality pitches and his secondary stuff didn’t show up and they hit him around.”

Cleveland showed its mettle, fighting back with five runs before the final inning, but could not overcome the big deficit.

“The guys swung the bat well, but we were in too big of a hole,” Acta said.

Acta said after the game that the team would option McAllister back to Columbus and recall Cord Phelps for his second stint with the Indians.

The Indians split a doubleheader against the Mariners at Progressive Field on Tuesday, winning the opening game 7-5 before dropping the nightcap, 12-7.

Shin-Soo Choo won Game 1 with a walk-off three-run home run after closer Chris Perez blew a save in the ninth.

The Mariners scored 10 times in 3 1/3 innings off Cleveland starter Zach McAllister to take control in the second game.

CLEVELAND — Another injury-plagued season could be over for Travis Hafner.

Hafner, who was placed on the disabled list Monday with a strained tendon in the bottom of his right foot, is expected to miss at least the next two weeks.

According to head trainer Lonnie Soloff, season-ending surgery is an option for Hafner. Soloff said the Indians would make a decision on the surgery over the next few days.

Hafner injured the foot earlier in the year and missed a handful of games without landing on the injured list. He aggravated the injury Sunday while running to second base.

“He was adamant about his desire to continue to play and support the team,” Soloff said. “Then he injured it again Sunday.”

Hafner, who is batting .281 with 11 home runs and 49 RBIs in 82 games, also spent time on the DL this season with a strained oblique muscle. If he does undergo year-ending surgery, he will have played in an average of 88 games in each of the last four seasons.

The Indians had plenty of other injury news:

**A lingering wrist ailment will sideline outfielder Michael Brantley until at least Friday. He missed both games of the doubleheader Tuesday.

“Michael can’t swing the bat,” Manager Manny Acta said. “Unfortunately, he’s not getting any better.”

Brantley will be examined Friday and if he is not ready to play, he will likely be placed on the DL.

**Grady Sizemore tested his injured right knee Tuesday with increased running and agility drills. He said Monday that he expects to begin playing in minor-league rehab games next week, but Soloff didn’t sound as certain.

“I trust Grady’s self-evaluation, but that’s not outlined as of yet,” Soloff said. “We have a lot of hurdles to get over.”

**General manager Chris Antonetti said Monday that he was optimistic that second baseman Jason Kipnis (hamstring) would return before the season is complete. The GM is hopeful that Kipnis will be activated around the time he is eligible to come off the DL, which is Monday.

**Soloff said right-hander Carlos Carrasco (right elbow inflammation) would not be able to pitch again until Sept. 1. If and when Carrasco is activated from the DL, he will still have to serve a six-game suspension.

Comings and goings

As was expected, Shelley Duncan rejoined the Indians from the family emergency list, with reliever Josh Judy optioned back to Triple-A Columbus to clear room on the roster for Duncan.

Right-hander Zach McAllister was officially recalled from Columbus to start the second game of the doubleheader. Infielder Luis Valbuena was sent back to the Clippers to clear room for McAllister.

Big league Choo

It was an eventful 24-plus hours for right fielder Shin-Soo Choo to say the least.

Choo was out of the lineup Monday for his wife’s birth of the couple’s first daughter, which occurred at 12:05 p.m.

He was still at the hospital Tuesday morning, arriving at the park at around 11 a.m. before hitting the game-winning home run in the first game of a doubleheader with the Mariners.

“I feel a lot of drama, like a movie,” Choo said. “I’m not an emotional guy, but running the bases, I was really thinking of my family. It’s the best present for my daughter, right?”

Choo was questionable for Tuesday’s first game. He said he received a call from the Indians at the hospital, then after clearing it with his wife, called them back and said he wanted to play.

“We didn’t even know if he was going to make it,” Acta said. “I’m glad he came.”

Minor details

Right fielder Travis Buck went 3-for-5 with a double and an RBI Monday in Columbus’ 6-4 loss to Buffalo. Buck, who has spent the majority of the season with the Indians, entered Tuesday batting .258 with three homers and 22 RBIs in 29 games for the Clippers. … Shortstop Juan Diaz had two of Double-A Akron’s three hits Monday in a 9-1 loss at Bowie. Diaz, who was acquired last year along with Ezequiel Carrera in a trade with Seattle for Russell Branyan, entered Tuesday hitting .255 with eight homers and 54 RBIs in 122 games for the Aeros.

COLUMBUS — Office buildings swayed near the Statehouse and the press box shook at a Cleveland Indians game Tuesday when a 5.9-magnitude earthquake in Virginia reached Ohio.

Tremors were felt in the state’s Appalachian region and stretched as far west as Dayton and to the north along Lake Erie.

No damages or injuries were reported in the first minutes after the quake in central Ohio or statewide, said Kelly Blackwell, spokeswoman for the Ohio Emergency Management Agency.

In Cincinnati, the National Underground Railroad Freedom Center, along the Ohio River, was briefly evacuated after tremors were felt.

Spokeswoman Stephanie Creech said a small group of elderly people from a nursing home were among the some 50 museum visitors and staff who moved outside for 20 to 25 minutes after the building’s floors shook.

“It was felt. Things moved on people’s desks,” she said. Among them: a bobblehead of Cincinnati Reds manager Dusty Baker, which began nodding vigorously.

“We took everybody out as a precaution. We’re very safety-conscious.”

She said she didn’t believe any of the museum’s artwork and photos fell from walls and there appeared to be no damage to other artifacts in the building, which shows the history of the network that helped Civil War era slaves escape.

The quake was felt sporadically in Columbus. Some visitors to the nearby Statehouse didn’t feel a thing, and nor did residents in the city’s northwestern suburbs a few miles from downtown. But southeast of the city, in Lancaster, people temporarily evacuated Fairfield County Municipal Court house.

A few dozen office workers were evacuated from a 13-story downtown Columbus building, but most were back inside in a few minutes. Some on the upper floors reported windows popping and ceiling tiles cracking.

One of the workers, banking assistant Amy Gentry, was going through email when she felt the quake, describing it as if “like a bulldozer might have hit it or something might have hit the building.”

“Nothing scary, just something out of the ordinary,” added Gentry, 25, who is from Columbus but hadn’t felt a quake before.

“It just doesn’t happen here,” she said.

In Sandusky in northwest Ohio, office employees at Cedar Point amusement park felt the quake, but none of the rides had to be shut down, said Robin Innes, a spokesman for the park along Lake Erie in Sandusky.

In Cleveland, the Indians and Seattle Mariners were in the first game of a double header when the press box above home plate and the third-base line moved left and right and some fans headed toward the exits. Play was not interrupted at Progressive Field, and the Indians reported no structural damage.

“I thought it was the wind. I know the stadium is made to move, but I didn’t know what was moving it,” said fan
