SEATTLE -- New Mariners general manager Jerry Dipoto made his first roster move on Monday, claiming right-handed pitcher Cody Martin off waivers from the Athletics.
There will certainly be more significant changes coming when free agency begins and the trade season heats up after the end of the World Series, but Dipoto has vowed to upgrade the Mariners' roster through every avenue available, and his first addition is this 26-year-old, who pitched in 25 games for the Braves and A's last year.
To make room on the 40-man roster, veteran right-hander Logan Kensing was released.
Martin went 2-3 with a 5.40 ERA in 21 games in relief for the Braves last year, then was acquired by Oakland in a July 2 trade. He appeared in four games for the A's, including two starts, going 0-2 with a 14.00 ERA.
Martin, a seventh-round Draft pick by the Braves in 2011, is 31-29 with a 3.24 ERA in 118 Minor League games. He was 1-3 with a 2.10 ERA in seven games (six starts) with Triple-A Gwinnett in the Braves' system and 4-4 with a 5.10 ERA in 11 starts for Triple-A Nashville in the A's organization this past year.
The Gonzaga University product provides a little depth for a Mariners system that was shy on Triple-A starters last season. He posted a 3.66 ERA in 58 games, including 54 starts, in Triple-A over the past three seasons.
Kensing, 33, went 2-1 with a 5.87 ERA in 19 relief appearances with Seattle after being recalled in late August. He also appeared in 19 games in his second season with Triple-A Tacoma, going 2-0 with one save and a 2.23 ERA after signing a Minor League contract with the Mariners on May 13.
