The infielder played for seven teams -- the Astros, Rays, Dodgers, Red Sox, Cardinals, Orioles and Braves -- but he was most known for his time in Boston.

After signing a four-year, $36 million contract with the Sox in 2006 -- he went on to help the team win the 2007 World Series.

Lugo logged 1,279 hits in his career ... and finished with 198 steals and a batting average of .269.

The death is the second tragic one in the MLB in less than two weeks ... former Mets reliever Pedro Feliciano also passed away at age 45 just 8 days ago.

RIP.
