OAKLAND -- The loss of Bartolo Colon for the rest of the season will resonate throughout the organization, general manager Billy Beane said.
"Travis [Blackley] had to throw a lot of innings Monday, and that has an effect today and tomorrow," Beane said on Wednesday. "We have this game today, and we have to think about tomorrow. Those decisions have a ripple effect through to Triple-A and the entire organization."
Blackley would have been the logical choice to start Thursday's game against Tampa Bay, but the left-hander threw 5 2/3 innings in Oakland's 7-2 loss to Minnesota on Monday night. He saved the bullpen that day but made himself unavailable for Thursday.
Tyson Ross, who had been scheduled to pitch on Wednesday night in Sacramento against the Salt Lake City Bees, was recalled to make the start instead.
Ross joined the team in Oakland in time to make the trip.
"I've been in Sacramento the past 2 1/2 months getting a chance to work a few things out," Ross said. "I feel like I've gone in the right direction."
Ross is 5-2 with a 2.74 ERA with the River Cats and has allowed two runs on six hits over his last 10 2/3 innings.
• Infielder Eric Sogard was 2-for-2 in a rehab start with Sacramento on Monday night. He did not play Tuesday.
• Infielder Jemile Weeks, optioned to the River Cats on Tuesday, can still take up to 48 hours to report.
•The A's rank last in the Majors with a .232 batting average. The lowest average in Oakland history is .236 in 1982. The lowest average in franchise history is .223 in 1908.
• Yoenis Cespedes hit a two-run single in the third inning and extended his hitting streak to eight games.
