Quick Hits: Padres, Wainwright, Posey, Theriot

Cubs starting pitcher and extension candidate Jeff Samardzija struggled on the hill at times tonight, but showed a new way to add value by launching his second long ball of the spring and adding another base hit (along with a sacrifice bunt). Indeed, Samardzija's work on offense was so impressive that he was allowed to take his final plate appearance before being lifted for a reliever in the bottom of the inning.

• With the first four spots in the Padres rotation all but locked down by Edinson Volquez, Clayton Richard, Jason Marquis, and Eric Stults, the club could be eyeing outside options for starter number five, writes Corey Brock of MLB.com. Brock notes that in-house options include Tyson Ross, Andrew Cashner, Tim Stauffer, and Freddy Garcia. San Diego was also recently linked to the Tigers' Rick Porcello. GM Josh Byrnes was not shy in acknowledging his interest: "Our scouts are out there, and we're talking to a few clubs." 
• Extension discussions between the Cardinals and starter Adam Wainwright still appear to be moving in a positive direction, reports Jon Heyman of CBSSports.com. Said Wainwright: "I think both sides feel confident something could get done." We learned earlier today that talks were progressing.  
• An extension agreement between the Giants and star catcher Buster Posey could take many forms, which serves to complicate negotiations, according to Henry Schulman of the San Francisco Chronicle. The Giants and Posey will likely discuss "a three-year deal that buys out arbitration, a different mid-range deal that cuts into free agency and the so-called 'megadeal' that locks Posey into San Francisco for a decade."
• Infielder Ryan Theriot remains unsigned after playing last year with the world-champion Giants, and San Francisco GM Brian Sabean says that the club has "lost contact" with the 33-year-old, reports Schulman. Theriot remains interested in playing, but so far has not received an offer that is "exactly what I'm looking for playing-time-wise." If the right opportunity does not come along, the easy-going Theriot seems to be at peace with moving on from the game to spend time with his young family.
