Things are trending downward for the Oakland A's. They have lost a season-high four straight games, and Bartolo Colon who looked like a steal after starting the season 3-1, has gone 1-4 since. The A's struggles couldn't come at a worse time. The Yankees' 9-2 victory means they have won 12 of their last 13 games at the Oakland Coliseum. "I am just pitching the same way I did at the beginning of the season," Colon said. "The difference is that I throw a lot of strikes and sometimes they take advantage of that."Colon, allowed six earned runs in six innings of work. He gave up nine hits, two of which were home runs. He was out-dueled by another former Cy Young Award winner in C.C. Sabathia, who allowed two runs over seven innings of work. "I think different lineups are a lot more difficult to navigate through," Melvin said. "And this one is one of them." Saturday's game played out a lot like Friday's game. In both contests a defensive lapse prolonged an inning that ended up resulting in a big hit by Mark Teixeira. On Saturday, Teixeira's big hit came in the form of a two-out, two-RBI single in the fifth inning.Teixeira never would have stepped to the plate that inning if it wasn't for a Derek Jeter bunt attempt that was botched by the A's. When Jeter bunted, both Colon and first baseman Adam Rosales went for the ball. Colon fielded the ball cleanly, but no one was at first base to take the throw. Instead of being out at first, Jeter recorded his 3,154th hit, which tied him with George Brett for 14th on Major League Baseball's all-time hit list."Adam Rosales probably breaks a little early," Melvin said. "You have got to have a little bit of a read. In his defense, he hasn't played that much first base." Rosales has only played in eight games in the past two seasons for the A's. Later in the inning, Alex Rodriguez hit a sacrifice fly that would have been the third out of the inning. Next, Robinson Cano doubled and Mark Teixeira hit the aforementioned two-run single.Much like Friday's game, Reddick hit a solo homer. It was his 13th of the season, and he has nine home runs in the Month of May -- the best month by an Athletic since Frank Thomas hit 10 in September of 2006. Unfortunately for the A's offense, Reddick seems to be the only hitter providing consistent production at the plate."Everybody would like to have guys on base, but I wouldn't say frustrating is the word," Reddick said. "I am happy I am swinging the bat the way I am. It's just unfortunate we're not winning the games. So hopefully I can stay consistent like this until these guys get fired up, and we can do some damage."Help could be on the way for the A's offense. Brandon Inge, Yoenis Cespedes, and Manny Ramirez could all join the team on the upcoming road road trip. Before they hit the road the A's will have to try and find away to beat the Yankees at the Coliseum in the series finale. Something they haven't been able to do since 2010. NOTES: In the eighth inning, Monday's probable starting pitcher Graham Godfrey entered the game in relief. He pitched two innings, allowing three runs, two of which were earned. Godfrey plunked Derek Jeter in the shoulder with the bases loaded, and gave up a two-run homer to Mark Teixeira, who also hit a home run in the fourth inning. Godfrey injured the middle finger of his pitching hand prior to his last start. He threw a bullpen session before the game.After the game, Bob Melvin announced that left-handed pitcher Travis Blackley will start the game on Monday against the Twins.
