A big reason for the maintained success -- the A's are tied with the Orioles for the second Wild Card spot -- is contributions from newcomers.
"We've gotten lifts from any number of guys over the course of the season from our system," manager Bob Melvin said. "Going out and getting a Brandon Inge, Stephen Drew, the front office has been pretty spot-on on targeting people at the right times. Whether it's Chris Carter at that particular time, whether it was Brandon Moss before him -- the Player of the Week at Colorado -- we've gotten a lot of contributions from probably a 30-plus-man pool within our system and going out and implementing a couple of guys from some other teams, too.
"The front office has been very, very good to this point. You bring up Chris Carter, hitting in the middle of the order, from the day he got here he was getting big hits for us. He's been a big pick-me-up."
The Indians, on the other hand, are far enough back that the playoffs are all but out of sight. Personnel wise, though, there are still opportunities for the Tribe as the season nears an end.
"We've got to get better," Jason Kipnis said. "Winning games right now, as far back as we are, as much as it stinks to say, it's not going to change too much. I don't see us making up 16 games in the last month.
"What is important is I think we need to get better in all aspects. Not just as a team, but all of us players need to get better. I need to get better. We need to take something out of this."
A's: Hottest team in Majors since July
At 70-57, the A's are more than 12 games over .500 for the first time since they finished the 2006 season 93-69. Additionally, Oakland's 32-15 record is the best in the Majors since the start of July.
Brett Anderson threw seven scoreless innings on Monday and has given up just one run in 14 innings (two starts) since being reinstated from the disabled list. Anderson was on the 60-day DL after undergoing Tommy John surgery.
Tommy Milone takes his 10-9 record and 3.87 ERA to the mound on Tuesday to face the Indians. The lefty starter is fresh off a win that snapped his career-high losing streak of three games.
Indians: McAllister gets the start
Right-hander Zach McAllister gets the start on Tuesday with an extra day of rest. McAllister has no-decisions in his last two appearances. McAllister is 5-4 with a 3.50 ERA this season in 15 starts.
Indians starter Roberto Hernandez left Monday's game in the third inning with a sprained right ankle. Hernandez is day to day, according to the Indians.
With a win in the series opener on Monday, the A's guaranteed themselves a split, at the very least, in the season series with the Indians. The A's are 5-2 against the Indians, with the two teams facing off three more times in 2012.
