​One of the biggest parts of the rebuild that took the ​Houston Astros from the doldrums of the American League West to the top of the sport was the acquisition of ​Marwin Gonzalez

Gonzalez was selected in the 2011 Rule 5 Draft by the Boston Red Sox and was then traded to the Houston Astros. Gonzalez experienced plenty of losing at the start of his career with Houston but eventually became a super-utility player on one of the best teams in baseball.

Teammate Jose Altuve is a big fan of his teammate's contributions to the club and has high praise for Gonzalez as he enters free agency. 

​​Gonzalez had his best season during the Astros' World Series run of 2017, hitting .303 with 23 home runs and 90 RBI. Last year, Gonzalez was not quite as productive on the surface, as his batting average fell to .247, but he still drove in 68 runs. 

Still, Gonzalez has the defensive versatility that teams crave nowadays and he played every position on the field except pitcher and catcher this season. This versatility is going to make him one of the hottest commodities on the open market. 

​​Having Gonzalez, or "Swiss G," as Scott Boras would rather you call him, has been a huge advantage for the Astros, masking holes and improving their ability to withstand injuries in a long regular season. 

If they are not willing to pay what could turn into a hefty price tag, then Houston may be left without the security blanket that they have so heavily relied on over the last couple of years.
