NL West Notes: Theriot, Padres, Diamondbacks

Jamie Moyer pitched four perfect innings against the Giants last night, and the 49-year-old's teammates were impressed with his approach, even if the opposition wasn't intimidated by his 80mph offerings. "To be able to move and get on the field, much less compete, is amazing,'' Michael Cuddyer told Jon Heyman of CBSSports.com. Here are some more notes from the NL West…

• Ryan Theriot’s $1.25MM contract becomes guaranteed if the Giants don’t remove him from the roster by March 29th, Henry Schulman of the San Francisco Chronicle writes. If they cut the infielder within the week, they’ll only owe him $312.5K, but the decision’s about more than the bottom line. Freddy Sanchez may start the season on the disabled list, and the Giants may want to bench Brandon Crawford against tough lefties. In other words, having Theriot on the roster could prove useful.
• Tom Krasovic of Inside the Padres offers a Q&A about the Padres' leadership in light of Jeff Moorad's decision to step down as the club's CEO. Krasovic hears that the Padres "are headed to another owner" than Moorad or current owner John Moores.
• Yahoo's Tim Brown makes the case that the next Dodgers owner would do well to keep manager Don Mattingly in place.
• Manager Kirk Gibson says the Diamondbacks are "underdogs" entering the season, Mike Bauman of MLB.com writes. "That's just the kind of attitude you've got to take. You can't anything for granted," Gibson said. The Diamondbacks won the NL West with 94 regular season wins in 2011 and seem poised for another strong season.
• Rockies third base prospect Nolan Arenado should be at the Major League level before long, even though he probably won't be on the Opening Day roster Heyman tweets.
