Diamondbacks to announce Johnson trade today

PHOENIX -- Randy Johnson took his physical Monday, and the Arizona Diamondbacks scheduled a news conference for today as their deal to reacquire the Big Unit from the New York Yankees neared completion.

Not that he needs an introduction. The Big Unit's best years were in Arizona, where he was 103-49 in six seasons and won four Cy Young Awards before going to the Yankees in a trade he sought in 2005.

After two difficult seasons in New York, Johnson returns to the Diamondbacks with a two-year, $26 million contract. The 43-year-old left-hander, who is waiving his no-trade clause, is being acquired for right-handed reliever Luis Vizcaino and minor league right-handers Ross Ohlendorf and Steven Jackson, and shortstop Alberto Gonzalez.

New York also agreed to pay $2 million of Johnson's salary this year. Because of the cash involved, the deal is subject to approval by commissioner Bud Selig.

Although the Diamondbacks made no comment on the physical, the team scheduled a 2 p.m. news conference in the home clubhouse at Chase Field.
