Cahill will take the mound for the final time this season Tuesday night as the visiting Athletics look to even a series with the Seattle Mariners.
Cahill (11-14, 4.31 ERA) emerged as Oakland’s ace last season, going a career-best 18-8 with a 2.97 ERA. He got off to a hot start this year, opening 6-0 with a 1.72 ERA while allowing either one run or none in seven of his first eight starts.
The right-hander then lost five straight decisions and is 5-14 with a 5.22 ERA since May 15. He didn’t get a decision in a 4-3 win over Texas on Thursday after allowing three runs and 10 hits in 6 2-3 innings.
“He threw a lot more strikes than balls, he got ahead in the count and gave up some hits, but when you’re working with strike one and ahead of the count, it gives you that much more confidence as a pitcher,” manager Bob Melvin told the A’s official website.
Cahill is 2-1 with a 3.71 ERA in five starts against the Mariners this year. The loss came Aug. 1 at Safeco Field, when he yielded seven runs and a season-high 12 hits in four innings of an 8-4 defeat.
The 22-year-old rookie right-hander is 2-0 with a 2.11 ERA in his last three starts. After home wins over Kansas City and Texas, Beavan didn’t get a decision in Seattle’s 3-2 loss to Minnesota on Thursday. He allowed two runs through seven innings.
Beavan (5-5, 3.82) yielded four runs and seven hits in five innings of the Mariners’ 8-5 loss Sept. 4 at Oakland.
Seattle (67-93) snapped a four-game skid with a 4-2 win in Monday’s series opener. Justin Smoak(notes) hit a three-run homer and Miguel Olivo(notes) added a solo shot for the Mariners, who improved to 10-7 against Oakland to clinch the season series.
Smoak is hitting .318 with four home runs and 14 RBI since coming off the disabled list Sept. 2 due to a broken nose. The first baseman has also missed time this year with groin and thumb injuries, but has still played in a career-high 121 games.
“It’s been a lot of ups and downs, too much watching games and not playing. It’s been a learning experience and I know what I need to do this offseason to get prepared for a full big-league season,” said Smoak, 3 for 14 with six strikeouts in his brief career against Cahill.
Hideki Matsui(notes) and Josh Willingham(notes) knocked in the only runs Monday for Oakland (72-88), which fell to 2-2 on a season-closing six-game road trip. Matsui ended a personal 13-game drought without an RBI - the longest stretch in his nine-year career.
Matsui is 3 for 5 against Beavan.
