Odds & Ends: Bumgarner, Tracy, Oswalt, Atkins

Links for Friday night, as Edwin Jackson tosses a 149-pitch no-hitter against his former team….

• Madison Bumgarner was scratched from tonight's Triple-A start, fueling speculation that the Giants would call him up to start tomorrow's game. However, Henry Schulman of the San Francisco Chronicle tweets that the team still plans to start Joe Martinez tomorrow, with Bumgarner as the backup option.
• In his weekly appearance on WEEI's Big Show, Peter Gammons discusses the Red Sox' bullpen issues and the best one-year signing of this past offseason.
• Bill Ladson of MLB.com wonders if the Nationals will be interested in the recently DFA'd Chad Tracy, given Tracy's connection to Nats GM Mike Rizzo.
• Although it looks as if the Rangers won't be able to afford Roy Oswalt, you can add Texas to the list of teams the pitcher would be willing to play for, according to the Dallas Morning News. Oswalt has previously said he'd accept a trade to anywhere he could contend.
• Garrett Atkins tells MLB.com's Brittany Ghiroli (Twitter link) that being released by the Orioles would be a "welcome opportunity." It appears as though Atkins will soon be designated for assignment.
• Following a blow-up during today's game, Carlos Zambrano has been suspended indefinitely by the Cubs, according to Paul Sullivan of the Chicago Tribune. When Zambrano returned to the Cubs' rotation, we discussed Tom Gorzelanny as a trade chip, but as long as Zambrano remains suspended, that possibility looks less likely.
• The Astros signed their second-round pick, right-hander Vincent Velasquez, per a team release.
• Dusty Baker says Gary Matthews Jr. "has got to get his act together" before the outfielder earns a shot at the Reds' big league lineup, writes MLB.com's Mark Sheldon.
