National League West Nuggets to Know

Arizona Diamondbacks

They struck out a major-league record 1,529 times in 2010. However, two players no longer with the team -- Mark Reynolds and Adam LaRoche -- accounted for 25 percent of those strikeouts (383 of 1,529).

Gerardo Parra was second among all leftfielders in 2010 with a +/- rating of +19. (Parra turned 19 more batted balls into outs than the average left fielder would have.) The only left fielder with a better +/- than Parra last season was Carl Crawford.

Colorado Rockies

The Rockies hit .298 at home in 2010, but just .226 on the road. The 72-point differential in their home-road batting average was the worst in baseball.

Carlos Gonzalez was one of 15 players who hit 30 home runs and had 100 RBI last season. Of those 15 players, Gonzalez drew the fewest walks (40).

Los Angeles Dodgers

Once again, the Dodgers will have a big question mark in left field. (Currently, Jay Gibbons and Marcus Thames are the leading candidates for the starting position.) In 2010, the Dodgers' leftfielders combined to hit .261, with a .322 on-base percentage and .392 slugging percentage. Those numbers were the lowest for Los Angeles' leftfielders in all three categories since 2005.

Despite playing 162 games for the first time in his career, Matt Kemp saw his batting average, OBP and slugging percentage all drop at least 40 points from 2009 to 2010. He also struck out 31 more times, from 139 to a career-high 170.

San Diego Padres

There's no replacing Adrian Gonzalez's offensive production, one reason why their offseason moves might have revolved around improving defensively. New second baseman Orlando Hudson was a major-league best +23 among second basemen last season. New shortstop Jason Bartlett ranked ninth at his position, +6.

The core of their bullpen, the best in the majors last season, returns in 2011. The Padres’ relief corps ranked first or second in ERA, opponents’ batting average, strikeouts per 9 IP and strikeout-to-walk ratio, and fourth in home runs per 9 IP. Their strikeout-to-walk ratio was 18 percent higher than the next-best team.

San Francisco Giants

Barring injury, Tim Lincecum likely will become the eighth pitcher in the modern era (since 1900) with 1,000 strikeouts in his first five seasons. The seven pitchers who reached this milestone: Tom Seaver (1,155), Bert Blyleven (1,094), Dwight Gooden (1,067), Kerry Wood (1,065), Grover Cleveland Alexander (1,036), Hideo Nomo (1,031) and Mark Langston (1,018). In four seasons, Lincecum has 907 career strikeouts.

The Giants finished the season on a tear thanks to their pitchers, who put together one of the best calendar months in the live ball era (since 1920). The Giants posted a 1.78 ERA in September, the fifth-lowest in a month since 1920, and their .182 opponents’ batting average was the second-best for a single month in that span.
