With his club falling further out of playoff contention by the day, Giants General Manager Brian Sabean started making sweeping changes Wednesday.
Outfielder Aaron Rowand and infielder Miguel Tejada were designated for assignment by the defending World Series champions, who began the day trailing first-place Arizona by a season-high six games in the NL West race.
"We're at a spot in the season where we have to do some damage control with the roster. ... If this stays ugly, we've got to turn the page, look at some other people and get ready for next year," Sabean said.
Sabean said he was working to try to move both players to other clubs within the day so they could "continue their careers." The Giants have 10 days to trade or release each player, but would have to trade them to a contender before Thursday for them to be eligible for another team's post-season roster.

Mets, Nationals to remember 9/11
To commemorate the 10th anniversary of the terrorist attacks on New York and Washington in 2001 and honor the memory of the victims, the Mets will wear the hats of first responders and service agencies for their game against the Cubs on Sept. 11. Former Mets pitcher John Franco, a New York native, will throw out a ceremonial first pitch to Mike Piazza, whose memorable homer provided the decisive runs in the first baseball game played in New York after the attacks.
Braves bring back Diaz
Matt Diaz returned to the Braves in a trade with Pittsburgh and started in right field against the Nationals on Wednesday night. The NL wild card-leading Braves acquired Diaz for a player to be named and cash considerations on Wednesday. The deal was completed in time for 33-year-old Diaz to be eligible for the post-season roster.
Diaz left the Braves after the 2010 season to sign a two-year, $4.25 million deal with the Pirates. He hit .259 with 12 doubles and 19 RBI in 100 games with Pittsburgh.
■ The AL West-leading Rangers made a pair of trades to strengthen their roster for the stretch run, acquiring reliever Mike Gonzalez and bringing back catcher Matt Treanor. The Rangers got Treanor from the Royals for a player to be named or cash.
Gonzalez was 2-2 with a 4.27 ERA in 49 relief appearances for Baltimore, which traded him to Texas for a player to be named.
■ Indians designated hitter Travis Hafner received "encouraging" news from doctors about his foot injury and could soon return for the playoff chase.

■ The Phillies acquired right fielder John Bowker from the Pirates on Wednesday for a player to be named or cash, adding a left-handed hitter to their bench. The 28-year-old Bowker batted .306 for Triple-A Indianapolis with 15 homers and 76 RBI.
