"Dex is grinding through some stuff now like a lot of our guys are," Weiss said. "The guys at the top of the order are paramount to an offense's success. Dex has always been an on-base guy, and he's unique in that he combines power with that ability to get on base. He's grinding through some things right now, but he's working hard. Our offense is too good to be down consistently. We've shown signs of life here over the last few days, but I just think it's too talented an offense to stay down too long."
• Marco Scutaro, the Rockies' 2012 Opening Day second baseman, returned as a member of the Giants on Thursday. Scutaro hit .362 in 61 games with the Giants after a midseason trade last year, and he paced them through the post season, winning NLCS MVP honors as he hit .500 (14-for-28) with six runs in seven games.
"I'm a big fan of Marco's, but don't tell him that," Weiss said. "I've always enjoyed the way he plays the game. He's well respected. The guys here know him and they have a lot of respect for him, and the league respects him because of the way he plays the game."
• Weiss said he was not opposed to the notion of increased use of instant replay in baseball, as long as it can be handled in a way that doesn't disrupt the flow of the game.
"I'm open to more conversation about getting it right," Weiss said. "There are plays that are difficult to see with the naked eye."
