The Arizona Diamondbacks have exercised Paul Goldschmidt's $14.5 million option for next season.

Goldschmidt signed an extension in March 2013 and 2019 is the final option year.

He posted a .290/.389/.533 slash with 33 home runs in 2018.

The San Francisco Giants have exercised Madison Bumgarner's $12 million option for 2019.

They also exercised Pablo Sandoval's option for the $555,000 minimum.

Bumgarner signed a six-year, $35.56 million deal in April 2012 that included $12 million club options for the 2018 and '19 seasons.

Sandoval, the 2012 World Series MVP, is recovering from right hamstring surgery and didn't play after July 29.

The Tampa Bay Rays have agreed to a $2.61 million signing bonus with 16-year-old Cuban pitching prospect Sandy Gaston.

The deal is pending a physical.

A hard-throwing right-hander, Gaston is considered one of the top international free-agent prospects and received attention from several teams, including the Miami Marlins and Baltimore Orioles.

The Arizona Diamondbacks announced they have agreed to terms on a three-year deal with infielder Eduardo Escobar that runs through the 2021 season.

Financial details weren't released by the club, but the contract is worth $21 million, according to MLB.com.
