Mike Fiers allowed five runs over three innings in a loss to the Mariners on Wednesday.

Fiers didn’t have much trouble over the first two innings, but did he ever run into trouble in the third. He allowed an RBI single to Dee Gordon, and a few batters later, Domingo Santana unloaded on a fastball for an opposite-field grand slam to give the Mariners a 5-2 lead. Fiers mostly pitched well for the A’s after coming over from the Tigers last year, but Wednesday morning was an example of what happens when he doesn’t have his best command. He’ll likely make his next start next Thursday in the homer opener against the Angels.

Mike Fiers allowed five runs over 3 1/3 innings in a Cactus League start against the Cubs on Wednesday.

Fiers surrendered eight hits, including three homers, and recorded only two strikeouts. The 33-year-old right-hander has given up six runs on 11 hits with seven strikeouts and one walk in 6 1/3 innings this spring. Despite the rocky outing, Fiers is an intriguing streaming candidate in deeper formats against the Mariners on Opening Day in Japan next week.

Mike Fiers will start for the Athletics on Opening Day against the Mariners in Tokyo, Japan.

Fiers will square off against Marco Gonzales of the Mariners. Marco Estrada will start the second game of the series against Yusei Kikuchi. Fiers split last season between the Tigers and Athletics, going 12-8 with a 3.56 ERA in 30 starts and one relief appearance.
