Sources: Olivera weighing 4- to 6-year offers

Cuban second baseman has piqued interest of at least six big league teams

Sources: Olivera weighing 4- to 6-year offers

Cuban second baseman Hector Olivera is considering several offers in the four- to six-year range, and the infielder could come to terms with a team this week, according to industry sources.

The Dodgers, Braves, Marlins, Padres, A's and Giants have all shown a strong interest in signing the 29-year-old, sources said.

Here's what we know: Scouts rave about Olivera's tools and international experience. He is also believed to be Major League-ready.

But Olivera, who will be 30 on April 5, is a complex case. Some front-office officials have expressed concerns about offering him a long-term deal because of his age, and others are wary of a blood disorder that sidelined him from play in Cuba's top league, Serie Nacional. The recent report by Yahoo! Sports claiming there is concern that Olivera has a damaged ulnar collateral ligament in his throwing arm also has some teams on alert.

For his part, Olivera claims to be completely healthy and denies any issues with his elbow. He has passed physical examinations in the Dominican Republic by four teams and continues to work out every day.

One of the most prolific offensive players in Cuba when healthy, Olivera wowed scouts in open showcases and private workouts in the Dominican Republic last month, underscoring the notion that he can hit at least 15 to 20 home runs and drive in 75 runs from the middle of a Major League lineup in what would be his rookie year. On defense, Olivera can play second and third base, which is also appealing to clubs.

On Monday, he dismissed his trainer and agent, and he's now being represented by Greg Genske of the Legacy Agency.
