NEW YORK -- The Yankees acquired 29-year-old first baseman Travis Ishikawa off waivers from the Orioles, the team announced on Twitter.
Ishikawa was designated for assignment on June 29. Ishikawa played in just six games with the Orioles this year, hitting .118 with one RBI. For his career, which also included time with the Giants and Brewers, Ishikawa is a .260 hitter.
The Yankees could use a backup first baseman as Lyle Overbay is the only true first baseman on the roster. Outfielder Vernon Wells has been taking grounders at first but has never played the position in his major league career.
To place Ishikawa on the 40-man roster, the Yankees transferred third baseman Kevin Youkilis to the 60-day disabled list. The Yankees said they will make a corresponding move for the 25-man roster when Ishikawa reports.
