Matt Stairs ties a major league mark when he homers for his eleventh team in San Diego’s 2-1 inter-league victory in Seattle. The Padres designated hitter’s fourth-inning homer off Ian Snell ties Todd Zeile’s record, who accomplished the feat by going deep in an Expo uniform in 2003.

After setting the mark in his previous game, Mike Redmond’s major league record errorless-streak behind the plate comes to an end when his throw to second base, trying to thwart a would-be base stealer, skips past Mark Grudzielanek. The Indians catcher’s streak started on July 22, 2004, and covered a span of 253 games.

Gio Gonzalez of the Athletics has the best outing of his career so far, tossing 8 shutout innings in beating San Francisco, 1 – 0. He retires the final 20 batters he faces before manager Bob Geren gives the ball to Andrew Bailey to pitch the 9th. However, the news is not all good for Oakland: they place long-time 3B Eric Chavez on the disabled list with two bulging disks in his neck; Chavez, who has been bothered by injuries continually since 2007, hints that his career may be over. He is hitting .234 with one homer in 33 games and has been used almost exclusively as a designated hitter. He won’t play for Oakland again, but will make a successful comeback as a back-up with the Yankees next season.

Daisuke Matsuzaka and Daniel Bard combine on a one-hitter as Boston defeats Philadelphia, 5 – 0. The Phils’ only hit comes with two out in the 8th, when Juan Castro drops a pop-up just beyond the reach of shortstop Marco Scutaro.

The Blue Jays blast six home runs against the Arizona Diamondbacks, but they’re all solo shots. They lose, 8 – 6, wasting a three-homer effort by Edwin Encarnacion; Fred Lewis also leads off the contest with a long ball, to no avail. Since 1920, only one other team has scored six runs, all on solo homers, in a game: the Athletics in 1991.

Houston Astros ace Roy Oswalt vents his frustration about pitching in front of the worst offense in the major leagues, saying he is willing to waive his no-trade clause. With the team headed for a third straight losing season, Oswalt has a sparkling 2.66 ERA but is only 2-6 because of the lack of support. In today’s game, Houston scores only two runs, but still tops the major league-leading Tampa Bay Rays, 2 – 1, thanks to a stellar start by Brett Myers. Oswalt will be traded to Philadelphia later this season.

Cardinals pitcher Brad Penny makes his mark with the bat, connecting for a grand slam in the 3rd inning, but then has to leave the game shortly afterwards with a back injury. The Cardinals beat the Angels, 9 – 5, as reliever Jason Motte picks up the win.

Trailing the Reds 9-3 starting the bottom of the ninth, Brooks Conrad’s pinch-hit grand slam gives the Braves an amazing 10-9 walk-off victory at Turner Field. The seven-run frame’s big blow by the 30 year-old journeyman barely clears the fence, with the ball deflecting off Laynce Nix’s glove when the left fielder reaches over the top of the wall at the 380-foot sign.

The Braves score a 9th-inning touchdown to overtake the Reds, after trailing 8 – 0 earlier and being down by 6 when the fateful inning starts. After another good start by rookie Mike Leake, reliever Mike Lincoln gives up four consecutive singles to start the 9th, scoring two runs. He is replaced by Nick Masset, who walks Cody Ross to load the bases; Martin Prado follows with a apparent double play grounder, but 3B Miguel Cairo fails to get the ball out of his glove and the score is now 9 – 6. Arthur Rhodes strikes out Jason Heyward for the first out and Francisco Cordero comes out to face pinch-hitter Brooks Conrad. Conrad hits a drive to deep left field which deflects off the glove of Laynce Nix and falls in the stands for a walk-off grand slam. It is only the second time in major league history that a pinch-hit grand slam overcomes a three-run deficit to end a game; the first was on July 8, 1950, by Jack Phillips of the Pirates. Joey Votto also hit a grand slam earlier in the game for the Reds, and Craig Kimbrel earns his first big league win.
