The Giants purchased Kensuke Tanaka's contract from Triple-A and recalled left-handed pitcher Mike Kickham Tuesday afternoon. To make space on the roster, the Giants designated Cole Gillespie for assignment and placed Hector Sanchez on the 15-day disabled list with a strained right shoulder.
Tenaka, who will wear No. 37 and is expected to play left field, is batting .330 in 78 games with the Fresno Grizzlies this year. The 32-year-old rookie has drawn 29 walks to 25 strikeouts and has 20 stolen bases in 27 attempts.
According to Major League Rule 11(b)(1), a player who is optioned to the minors cannot be recalled until 10 days after he reports to the farm club. But the Giants can circumvent the rule with Kickham, who was optioned on Sunday, in order to fill the space vacated by the injured Sanchez. Kickham, 24, was moved to the bullpen after he lost his third consecutive start for the Giants on July 1 in Cincinnati. He is 0-3 with a 12.15 ERA in four outings this year.
Sanchez, 23, hasn't started a game since June 26 in Los Angeles. He's batting .231 in 26 games for the Giants this season.
Gillespie, 29, appeared in three games for the Giants, going 0-for-7 at the plate.
