Quick Hits: Cubs, Hudson, Hamilton

Cubs manager Dale Sveum is upset with his team's recent play and says that players who don't perform won't have big-league jobs, Gordon Wittenmyer of the Chicago Sun Times reports. That goes for top young players Starlin Castro and Anthony Rizzo. "I don’t think [anyone’s] invincible if you’re not performing," Sveum says regarding Castro and Rizzo. "It’s not about what we think can happen three or four years from now. It’s time to perform on a consistent basis."

Wittenmyer writes that Sveum's harsh words for Castro and Rizzo "threw a sudden dose of skepticism and doubt into the widespread assumptions about the Cubs’ core," but acknowledges that, in reality, Castro and Rizzo will be with the Cubs for the foreseeable future. Sveum is suggesting they might be demoted, but that seems extremely unlikely, and it's even less likely that either of them would be traded. The Cubs signed Castro to a seven-year, $60MM contract last August. Rizzo is not signed to a long-term deal. Both players have hit well this season despite occasional mistakes in the field. Here are more notes from around the majors.

• John Poloni — also known as the "fat scout" in Michael Lewis' Moneyball — lobbied for the Athletics to draft Tim Hudson in 1997, John Shea of the San Francisco Chronicle writes. Hudson wasn't regarded as a top draft prospect due to his size, but Poloni told the A's that Hudson had "the best sinker he'd ever seen." 16 years later, Hudson is nearing his 200th win in the big leagues. That doesn't mean Poloni is rushing to take credit, however. "He exceeded my expectations, too," Poloni says. "A lot of times, it's pure luck."
• Last offseason's big-ticket free agents haven't performed well so far, says the St. Louis Post-Dispatch's Rick Hummel. One of the highest-profile disappointments thus far has probably been Josh Hamilton of the Angels, although it's still early enough in the season that one big series could make any player's statistics look considerably better.
