The A's made another addition to their starting rotation Wednesday morning, acquiring veteran right-hander Tanner Roark and cash considerations from the Reds in exchange for minor league outfield prospect Jameson Hannah.

The trade was first reported by The Athletic's Ken Rosenthal, with MLB Network's Jon Heyman first to report that Hannah was heading to Cincinnati. The A's confirmed the deal later Wednesday afternoon.

Roark, 32, is 6-7 with a 4.24 ERA and 1.42 WHIP in 21 starts this season. In seven major league seasons, he is 70-61 with a 3.66 ERA and 1.23 WHIP.

Roark is earning $10 million this year and will be an unrestricted free agent at the end of the season. The San Francisco Chronicle's Susan Slusser reports that Cincinnati will pay the majority of his remaining salary, which is a little over $3 million.

Roark should slot in as Oakland's number two or three starter, joining Mike Fiers, Brett Anderson, Chris Bassitt, and Homer Bailey, with Daniel Mengden likely the odd man out. Bailey came over from Kansas City earlier this month in exchange for infield prospect Kevin Merrell.


Roark features a fastball, slider, curveball, and changeup, with an occasional cutter as well. He pitches well to contact and doesn't walk many hitters, which should benefit him in Oakland, especially with the A's strong defense behind him.

Hannah was ranked as the A's No. 8 prospect by MLB Pipeline. The 21-year-old is slashing .283/.341/.381 with two home runs, 25 doubles, 31 RBI and six stolen bases this season at High-A Stockton. He was Oakland's second-round draft pick in 2018 out of Dallas Baptist University.

While Hannah is a solid average hitter, he doesn't have great power, and the A's feature plenty of outfield depth, both in the majors and minors. Ultimately, that made him expendable.

This appears to be a beneficial trade for both teams.
