Bartolo Colon will look to give Oakland's bullpen some more rest against his former team on Saturday afternoon at Yankee Stadium, one day after A.J. Griffin tossed seven-plus shutout innings in a 2-0 A's win. Before Griffin's outing, Oakland starters managed to go just 6-11 with a 5.87 ERA over their prior 22 games.
"[The starters] don't take any satisfaction in knowing we're having to cover four innings a game sometimes with the bullpen," A's manager Bob Melvin said. "They have the ability to be better, and they will be."
Colon took a no-decision in his last start, against the Orioles on Sunday, allowing five runs on nine hits in six innings of work. Walking just one batter over his first five starts, Colon leads the Majors with the fewest walks per nine innings (0.28) and the highest strikeout-to-walk ratio (20.0).
However, Colon is 4-6 with a 6.23 ERA in 15 career appearances against the Yankees, his highest ERA against any American League team.
Facing Colon will be Yankees right-hander Phil Hughes, who is still looking for his first win of the season.
In his last start, against the Blue Jays on Sunday, Hughes took a no-decision, allowing just two runs on seven hits in six innings of work. It marked his third straight quality start since beginning the season with two straight losses.
The right-hander walked just one in the game and also struck out a season-high nine batters. Six of those strikeouts came in the first 12 batters he faced.
It marked another strong start for Hughes at Yankee Stadium, as the righty is 7-2 with a 3.20 ERA in his last 12 starts in the Bronx.
A's: Rosales bats in the leadoff spot
With Coco Crisp on the disabled list, Melvin had to shuffle his lineup for Friday's game against the Yankees. That meant giving Adam Rosales his first career start in the leadoff spot.
That proved to be the right move, with Rosales sending the first pitch he saw from CC Sabathia over the left-field wall for his first home run of the season. He finished the game going 2-for-5.
"Someone had to hit there," Melvin said before the game. "He's excited about it. We'll see where we go. That just shows you what we miss when Coco's not there. That's one of the no-brainers, as far as the lineup goes, when Coco is there, that he will lead off. At this point, we're just trying to mix and match on a particular day."
Yankees: Robertson works with Wounded Warriors
The Yankees announced on Friday that reliever David Robertson will be the team spokesperson for the Wounded Warrior Project, representing the organization in outreach efforts and participating in visits to Yankee Stadium.
"It's such a great cause. It's such a worthy thing to do," Robertson said. "These guys are out there on the front lines risking their lives.
"You can bring them hope, but the best thing is that you can spread the word. You can put the word out there that these guys are here and they need help getting eased back into their lives."
On Friday, the Yankees hosted approximately 25 members of the organization, all of whom were wounded while serving in the armed forces.
• The A's have a Major League-leading 142 walks this season.
• When leading after seven innings, the A's are a perfect 14-0 this season.
• The Yankees are 16-7 since April 7, after starting the season 1-4.
