Quick Hits: Guillen, Diamondbacks, Nava

White Sox executive Kenny Williams says baseball needs personalities like that of former manager Ozzie Guillen, Doug Padilla of ESPN Chicago writes. “I think it misses personality and characters and a guy who has had as much success as he has and has much baseball knowledge as he has and has a desire to be in uniform and should be in uniform somewhere,” says Williams. “Hopefully he gets another chance to show it.” Williams and Guillen had their differences when Guillen was with the White Sox, of course. The White Sox allowed Guillen to depart for Miami, where his tenure as manager of the Marlins was brief and unfortunate. He hasn’t managed since, although he’s expressed interest in returning. He now is an analyst for ESPN and ESPN Deportes. Here are more quick notes from around the Majors.

• Diamondbacks GM Dave Stewart sees pitching as the key to improving the franchise’s fortune, the New York Times writes. “Everything depends on pitching,” says Stewart. “So as quickly as our young pitchers can mature is going to determine whether we contend or don’t. I know we’re going to hit and catch the ball. Those things are givens.” The Diamondbacks’ emergence will thus depend on young pitchers like Jeremy Hellickson, Rubby De La Rosa, and Archie Bradley, who makes his big-league debut today.
• The Red Sox received inquiries about outfielder Daniel Nava this spring, Alex Speier of the Boston Globe tweets. The team declined to trade Nava despite a surplus in their outfield, however, feeling that Nava was more valuable in a Red Sox uniform than on the trade market.
