The Giants are one of several teams "showing strong interest" in Cuban second baseman Hector Olivera, according to MLB.com.

Olivera held a workout in the Dominican Republic last week and over 200 scouts were in attendance, according to the same report.

The 29-year-old Cuban has been linked to the A's throughout the offseason.

According to the latest report, in addition to the Giants, the Padres, Rangers, Braves and Yankees are interested in Olivera.

Olivera, listed at 6-foot-2 and 195 pounds, has not yet been cleared to sign with an MLB team. He left Cuba last September but still needs to clear a few hurdles before he can be declared a free agent.

There are some health concerns for Olivera, who reportedly missed the entire 2012-13 season with thrombosis in his left biceeps -- a potentially serious condition that blocks blood flow.

He returned last year and hit .316 with a .412 on-base percentage in 273 plate appearances with seven home runs, 38 walks and 25 strikeouts for Santiago De Cuba in Serie Nacional, though he spent the majority of his games as the designated hitter.
