"I'm happy to find a home, especially with the Reds, a great organization with a lot of history," Ross said after arriving at RFK Stadium in time to take batting practice before Cincinnati's game at the Washington Nationals. "It's an exciting time for me now."
Womack hadn't started since April 14 and was relegated to pinch-hitting occasionally after general manager Wayne Krivsky traded for second baseman Brandon Phillips on April 7.
"We just felt with the way the team's set up right now, his playing time is obviously not going to be what he thought it might be," Krivsky said. "We thought it best to do it now."
If the Reds can't trade Womack, he could become a free agent.
The Reds also put left-hander Eric Milton on the 15-day disabled list and called up right-handed starter Elizardo Ramirez from Triple-A Louisville to face Washington on Monday. Milton had surgery Monday to repair torn cartilage in his left knee. He's expected to be sidelined for three to four weeks.
Ross started two games for Los Angeles. He hit a grand slam and a three-run homer during a 13-5 victory over Pittsburgh on April 16 and was designated for assignment the next day.
"I talked to [manager Jerry Narron], and he just told me he's happy to have me and just to go out there and play hard. He didn't really tell me what my role's going to be. Whenever he calls my name, I'll say, 'All right, I'm ready to go,'" Ross said.
"Anytime you get on a new team, it's like a fresh start," he said.
Womack was one of the Reds' main offseason acquisitions under former general manager Dan O'Brien, who traded a pair of prospects to the Yankees for the second baseman/outfielder. The Yankees also sent the Reds $900,000 to cover part of Womack's $2 million salary this season, the last on his contract.
O'Brien then gave Ryan Freel a two-year, $3 million contract and brought Rich Aurilia back on a one-year deal, leaving the Reds with three second basemen. When Krivsky got Phillips from Cleveland in a trade, Womack's role was even more limited.
Phillips started all seven games last week and hit .452 with three homers and a league-high 17 RBI. He was honored as NL player of the week on Monday.
