OAKLAND -- Tommy Milone has allowed two grand slams this season. The A's ended up winning both of those games. It's not exactly the most sound strategy but it apparently works. After falling behind 4-0 after Shelley Duncan's fourth-inning grand slam, the A's battled back eventually winning the game 6-4. The heroics came an inning too early for pie though, as they rallied for two runs in the eighth to take the lead.Milone was pitching on extra rest and looked a lot sharper than the statistics indicate. He struck out six batters and allowed four earned runs over five innings of work. "Overall it went alright, I felt good out there," Milone said. "Obviously the rest helped. I think just that one pitch was the only mistake I made all game." Immediately after the Indians put the crooked number on the scoreboard in the fourth inning the A's rallied for three runs of their own. Their first run scored on a Josh Donaldson RBI double. The go-ahead run scored on a Donaldson RBI single. The young fill-in third baseman getting hits ended up being the theme of the evening. He went a career-high 4 for 4 with two RBIs. "I think it's awesome, that's a good thing for me," Donaldson said. "But just being around the team winning that's the most important thing. As long as I can contribute any way I can.""It's big with Brandon Inge being down," A's manager Bob Melvin said. "We're getting some production on the offensive side from third. We're feeling pretty good about it." Donaldson is just the latest success story to emerge from Triple-A Sacramento. Chris Carter, Brandon Moss, and Derek Norris are all becoming mainstays in Oakland. Donaldson could be next on the list if he keeps swinging the bat like he is. "There's not one at-bat in Sacramento where I'm tight, there's not one at-bat there where I'm like 'oh I've got to get a hit here,'" Donaldson said. "Being able to allow that to transfer over to the big leagues is just a big thing for me."Oakland also got key contributions from Cliff Pennington. He drove in two runs and snapped out of an 0 for 12 slump. "That's key, he's a guy that we need," Melvin said. "He expected to have a better offensive year."After Milone exited the game the A's bullpen held the Indians scoreless for four innings. Grant Balfour closed out the game for his 10th save by tossing a clean three up, three down inning. The A's have now won two games in a row. At 20-12 they still have the best record in Major League Baseball since the All-Star Break. The current A's were visited by the 2002 Moneyball A's that won a record 20-games in a row. They were also visited by Josh Reddick, who underwent another dental procedure before the game. He wasn't able to play but collected a pinch hit single to load the bases in the eighth inning.
