Mariners Claim Andrew Moore, Designate Nick Rumbelow

By Steve Adams | May 17, 2019 at 1:06pm CDT

The Mariners announced that they’ve claimed right-hander Andrew Moore off waivers from the Giants and designated right-hander Nick Rumbelow for assignment in order to open space on the 40-man roster.

Moore, 24, returns to the organization that selected him in the second round of the 2015 draft. He’d been traded to Tampa Bay as part of last season’s Denard Span/Alex Colome deal, but the Rays designated him for assignment last month after some considerable early-season struggles. The Giants claimed him two weeks ago but were apparently hoping to pass him through waivers in order to retain him without committing a 40-man roster spot.

Moore made just one appearance in the Giants organization and was torched for five runs in 1 2/3 innings for the club’s Double-A affiliate — a continuation of a disastrous start to the year in the Rays organization. With Tampa Bay, Moore served up 25 runs on 29 hits (none homers) and 10 walks in just 17 1/3 innings of work. His season ERA at the moment is 14.21, and he’s walked nearly as many batters (11) as he’s managed to strike out.

That said, Moore isn’t far removed from being a reasonably interesting pitching prospect. Prior to his arrival at the MLB level in 2017, he’d been touted as a potential fourth or fifth starter who relied on plus control and an above-average-to-plus changeup to compensate for his rather average fastball velocity. He turned in a 3.04 ERA with 8.1 K/9 and 1.8 BB/9 in a combined 109 2/3 innings between Double-A and Triple-A with the Mariners during that 2017 season as well.

The 27-year-old Rumbelow has allowed 16 runs in 15 2/3 Triple-A frames this season and another four runs in 1 1/3 innings at the MLB level. He showed some promise in the Mariners’ minor league ranks last year, notching a 1.83 ERA and a 26-to-8 K/BB ratio in 19 2/3 innings, but he’s yet to find any success in the Majors to this point in his career.

    He will probably replace Swanson in the rotation pretty soon.

      Perhaps, but I would think we have at least 1 more guy ahead of Moore on the depth chart.
      None are that great, except for maybe Sheffield. Jon niese maybe??

      No way that happens. Moore is trying to save his career. He’s starting in AA to try to get back on track. Swanson needs to go back to AAA but I’d expect its Milone that takes his spot as Sheffield is only other option on 40 man.

        Completely agree. Tommy Millone is the only SP that has been decent in AAA. Hopefully, Ljay Newsome keeps balling out in AA
