New York manager Joe Girardi said Monday that Capuano will go the bullpen when Tanaka rejoins the rotation for the season finale against Seattle on Wednesday.
Capuano is 0-3 with a 6.39 ERA in his three starts. Opponents are hitting .310 against the lefty and he gave up six hits and three earned runs in a season-high 5 1/3 innings last Friday in a loss to Oakland.
Girardi said the decision with Capuano also is an indication of how right-hander Adam Warren has pitched. Warren has made 10 starts and is 3-4 with a 3.75 ERA, with opponents hitting just .239. Warren has lost three of his last four decisions but pitched at least six innings in each start and allowed three earned runs or fewer.
