GOODYEAR, Ariz. -- The Indians' Spring Training roster is down to 34 after a couple of roster moves Thursday morning.

Looking for added bullpen depth, the Tribe claimed right-hander Jae Kuk Ryu off waivers from the Padres and optioned him to Triple-A Columbus. Ryu will go directly to Minor League camp.

To make room for Ryu, Jake Westbrook, recovering from Tommy John right elbow ligament replacement surgery, was placed on the 60-day disabled list. Westbrook isn't expected back until late June, at the earliest.

Ryu, a 25-year-old native of South Korea, is also trying to work his way back to the Majors after right elbow surgery. He had an arthroscopic procedure performed last July. As a result, Ryu appeared in just six games in the Rays' organization last year. He made five starts for Triple-A Durham and went 1-2 with a 4.38 ERA. He allowed 12 runs on 26 hits with 19 strikeouts in 24 2/3 innings. He also made one relief appearance for the Rays, working 1 1/3 scoreless innings.

The Padres had claimed Ryu off waivers in January and gave him a shot to make their bullpen. He proceeded to go 0-1 with a 10.61 ERA in eight appearances this spring, surrendering 12 runs (11 earned) on 16 hits in 9 1/3 innings. Eight of those runs came in one-third of an inning in an appearance against the Giants on Sunday.

In addition to claiming Ryu, the Indians also reassigned infielder Andy Cannizaro to Minor League camp. Cannizaro, 30, was in camp as a non-roster invitee. He's likely headed for Columbus, where he'll bounce around the infield. He's a lifetime .274 hitter in 734 Minor League games, and he's played 14 games in the Majors with the Yankees and Rays.

In 16 Cactus League games, Cannizaro made two starts at shortstop and 16 appearances overall, batting .227 (5-for-22) with a homer, two walks and two strikeouts.
