But there's no need to look any farther than the bullpen, where Travis Blackley has pitched from most recently. The left-hander has also started 10 games this season, appearing in relief six times.
"We've been looking for a way to try to give Parker and Milone a little bit of a break," Melvin said. "We are very cognizant of the workload of our younger pitchers, and we feel like this is a good time to be able to give them a little bit of a break, refresh them going forward for the rest of the season."
Blackley is in his first season with the A's after starting the season across the bay with the Giants. The lefty is 3-3 with a 3.62 ERA in his 10 starts, his last one coming on July 29 at Baltimore.
Blackley and the A's will be looking to cut into the deficit between themselves and the White Sox after losing to them in the series opener on Friday. The White Sox enter Saturday with a one-game lead over the Tigers in the American League Central, but are also 1 1/2 games ahead of the A's in the Wild Card hunt if Detroit overtakes them in the division.
That being said, Chicago manager Robin Ventura will not be looking at the standings or scoreboard any time soon.
"Again, we've got more than a month," Ventura said. "With two weeks left, you probably look at that a little bit more. You know, if you don't win games now it's not going to matter anyway. So continue to play, continue to just focus on what you're doing."
A's: McCarthy posts solid outing in return
Brandon McCarthy pitched six innings of three-run ball on Friday in his return to the field. McCarthy had been on the disabled list with a strained right shoulder since June 24. The right-hander received a no-decision, but gave up three home runs for the first time since May 13, 2009.
White Sox: Viciedo breaks out of slump
Dayan Viciedo is in the midst of a slump at the plate, hitting just 6-for-36 with two RBIs in his last 13 games. But the outfielder delivered on Friday, hitting a game-tying solo home run in the seventh inning.
Francisco Liriano will make his third start for the White Sox since joining the team via a trade on July 28. In his home debut on Aug. 5, Liriano received a no-decision after leaving the game after five innings because of a left quad contusion after being hit by a line drive.
The White Sox have won 10 of their last 13 one-run games after a 4-3 walk-off win over Oakland on Friday.
Blackley has never faced the White Sox, while Liriano has gone 3-4 with a 3.69 ERA in 13 games against the A's.
