Some of the Giants' final roster moves showed just how much they're trying to improve the depth of their offense, which ranked last in the Majors in runs scored a year ago. One sign is that they went to great lengths -- trading Chris Stewart to the Yankees and sending Eli Whiteside to the Minors -- to get 22-year-old catcher Hector Sanchez on the Opening Day roster. He'll be the backup to Buster Posey to start the season after elevating from Class A ball last year to prominence in the Giants' plans. "He's done a good job. He's earned this," Bochy said of Sanchez, who hit .383 with four homers while working with all the pitchers this spring. More evidence that the Giants want to have a little more offensive depth is how they kept Brett Pill on the roster as a bench player, giving the team an added boost in reserve from the right side of the plate. As the season begins, it's apparent Aubrey Huff will be the primary left fielder for the Giants. The domino effect of that, with newcomers Melky Cabrera in right and Angel Cabrera in center, is that Nate Schierholtz will begin the season looking for playing time. "I talked to Nate, and he knows this is how we're starting out," Bochy said. D-backs: Bullpen making late adjustments
With Takashi Saito's calf injury late in Spring Training, the D-backs made some alterations to their original plans and wound up holding on to Wade Miley as a long reliever to take Saito's spot, at least until the veteran reliever is eligible to return from the disabled list April 15. "Right now your starters aren't stretched out as much, so you tend to rely more on your bullpen," Arizona manager Kirk Gibson said. "I would rather do that than push the [starters] early in the season." After a 2011 season in which he hit career highs with 39 doubles, 31 homers and 88 RBIs, 24-year-old right fielder Justin Upton knows there's room for improvement heading into 2012. "I think as well as I hit last year, I wasn't as consistent as I could have been," Upton said. "I still hit those long slumps. I think being a good hitter is about being able to get out of those a little quicker and still producing when you're not feeling great. That's something that comes with time and being able to take a step back and play the game." Worth noting
The two teams have been in the NL West together since the D-backs entered the league in 1998, but this is the first time the D-backs have opened a season against the Giants. Entering their 15th season, this will mark the ninth time in franchise history the D-backs have opened at home. Overall, the Giants hold a 137-103 advantage over the D-backs, but the two teams split their 18 meetings in 2011. Pitching matchups for the remainder of the series: Lefty Madison Bumgarner will meet Arizona's Hudson on Saturday, and Cain will take on right-hander Josh Collmenter in the Sunday finale.
