What we’re watching: Giants aim for critical sweep

- Last night’s brawl will probably go down as an isolated incident, but there is the chance that some bad blood will spill over when the Blue Jays and Yankees face off again tonight. The pitching change makes it a little more likely. This was supposed to be a matchup of lefties Brian Tallet and Andy Pettitte, but Pettitte was scratched due to a shoulder issue and will be replaced by wild righty Chad Gaudin. Starting against the Jays 13 days ago, Gaudin hit two batters and walked three in 3 2/3 innings. - Maybe it’s time for the Rangers to start rooting for Boston? If the Red Sox can beat the Angels again, they’d have the better record of the two clubs, and the Rangers still have six games left against the Angels that they could potentially use to make up ground. The Red Sox will be going for their seventh straight win tonight with Paul Byrd on the mound. He’s 1-1 with a 6.08 ERA in three starts since joining the rotation. The Angels will turn to Joe Saunders, who has won four straight since coming off the DL. He’s 4-1 with a 3.25 ERA in seven career starts against Boston. Game of the Night Colorado vs. San Francisco - One more time, it’s Rockies vs. Giants for the game of the night. The Giants won the first two games of the series by a combined 19-3 score to pull within 2 1/2 games in the wild-card chase. Now the pressure is on Colorado to avoid the sweep with 14-game winner Jorge De La Rosa on the mound. De La Rosa has won both of his starts against the Giants this season, even though he allowed six runs in one of them, and is 5-0 with a 3.35 ERA against San Francisco in his career. Giants starter Matt Cain is 2-1 with a 3.60 ERA against the Rockies this season. Due to poor run support, he’s picked up a victory in just one of his last nine starts.
