Cincinnati Reds cut Kevin Quackenbush, activate Shackelford; could a Senzel move be coming?

The Reds shook up the roster a bit Tuesday. Out is right-hander Kevin Quackenbush. He was designated for assignment to make room on the roster for right-hander Kevin Shackelford.

But it could be a prelude to a bigger move. The 40-man roster is at 39, so there’s an opening if the Reds want to get top prospect Nick Senzel on the roster.

Quackenbush, 29, made the team out of spring training as a non-roster invitee. He appeared in 10 games and had an 11.00 ERA. He allowed six runs in the final game in St. Louis.

Shackelford, 28, has been on the disabled with a right forearm strain. Shackelford was 0-0 with 4.70 ERA in 30 games last year.

He came to the Reds in a trade for Jonathan Broxton on Aug. 31, 2014.

Senzel, 22, went into Tuesday hitting .259 overall for Triple-A Louisville. But he's come on lately. He was 11-for-33 since the slow start.
