Michael Bourn went from the bottom of the NL Central in Houston to the top of the wild-card standings with Atlanta. Other players joining the pennant race included Rafael Furcal, Mike Adams and Eric Bedard.
On a topsy-turvy weekend, the surprising Cleveland Indians, Pittsburgh Pirates and Arizona Diamondbacks made some of the boldest moves at the trade deadline, shedding those seller tags and shopping for immediate help.
It was a relatively quiet deadline day as the non-waiver cutoff came and went Sunday.
The Indians completed their Saturday night deal for Rockies ace Ubaldo Jimenez about a half-hour before the 4 p.m. EDT deadline. Pittsburgh dealt for San Diego outfielder Ryan Ludwick and the Diamondbacks bolstered their bullpen, adding Oakland submariner Brad Ziegler as they chase the World Series champion Giants in the NL West.
Among those staying put after weeks of speculation: Padres closer Heath Bell, Tampa Bay outfielder B.J. Upton and Astros lefty Wandy Rodriguez.
And standing pat, the New York Yankees, content to try and catch Boston in the AL East with a rotation that has reclamation projects Bartolo Colon and Freddy Garcia at the back end.
The Red Sox picked up a much-needed starter after a deal for Rich Harden fell through late Saturday, landing Bedard from Seattle in a three-team, seven-player trade involving the Los Angeles Dodgers.
Teams still can make trades for the rest of the season, but it becomes more complicated. Players must first pass through waivers, meaning any club can get an opportunity to claim them before a deal is done.
Trades must be completed before Aug. 31 for a player to be eligible for the postseason with his new team.
