VIERA, Fla. -- The Nationals put first baseman Josh Whitesell on waivers on Monday, and he was claimed by the Diamondbacks on Friday.
Last year was arguably Whitesell's best season in the Nationals' organization. He hit .284 with a career-high 21 home runs and a .425 on-base percentage for Double-A Harrisburg.
Going into that season, Whitesell, 25, had a reputation of being a mediocre first baseman, but he cut down on his errors and was named the Eastern League's best defensive first baseman in a survey conducted by Baseball America.
Whitesell was the Expos' sixth-round pick in the 2003 First-Year Player Draft.
