CHICAGO -- General manager Mark Shapiro said earlier this week he hated the thought of losing right-handed reliever Kaz Tadano.
"I think Kaz is a big leaguer," Shapiro said. "If we lose him, I'll feel bad about it. If we trade him, we won't get value that I think is [enough] value for him."
But any value is better than no value, of course. So the Indians shipped Tadano off to the A's on Tuesday in exchange for outfielder Ramon Alvarado.
Tadano, a 25-year-old native of Japan, was designated for assignment Saturday when the Indians set their Opening Day roster.
In three seasons with the organization, Tadano made 15 big-league appearances, including four starts, and compiled a 1-1 record and 4.47 ERA. He spent the majority of his time in the Minors with Triple-A Buffalo, and his Minor League record was 13-11 with a 3.42 ERA in 82 games.
In parting with Tadano, the Indians are gaining one of the more promising and explosive bats in the A's Minor League system.
The 20-year-old Alvarado is a product of Oakland's Dominican Baseball Academy. He spent his first three professional seasons in the Dominican Summer League before playing rookie ball last year.
With Oakland's rookie club in Arizona, Alvarado hit .296 (50-for-169) with six homers and 32 RBIs in 48 games. He also stole nine bases, scored 37 runs and finished fourth in the Arizona Rookie League in total bases (84), slugging percentage (.497) and extra-base hits (19). His six homers ranked second in the league.
The Indians have no further word on the status of infielder Brandon Phillips, who is also on the trading block after being designated for assignment Saturday. A deal is expected to be worked out sometime in the next few days.
