Mulder improved to 7-0 with a 1.98 ERA in eight career starts against Kansas City after throwing a four-hitter against the Royals on Saturday night.
“It was a dominating performance,” A’s manager Ken Macha said. “The way he goes through the middle of (Kansas City’s) lineup is pretty impressive.”
He had a season-high seven strikeouts in his second straight complete game and 19th of his career in the Athletics’ 3-1 victory.
Oakland comes into this series having won five of six, including a 3-2 win over Detroit on Thursday.
The Royals’ Brian Anderson will be looking to snap a personal five-game losing streak as he opposes Mulder in the series opener. Anderson’s last start was a 6-2 defeat to the A’s on Sunday.
It’s the second time in his career the left-hander has dropped five straight starts, the last time coming Aug.-Sept. 1995.
Kansas City, which came into Thursday’s game against Texas looking for a three-game sweep against the Rangers, instead had to settle for just a series win after a 6-3 loss.
