With Jansen entrenched as the Dodgers' closer, Vazquez would likely provide added support at the back end of the bullpen should L.A. acquire him.
The 27-year-old left-hander has converted 19-of-20 saves this season for Pittsburgh while posting a 1.91 ERA and 13.9 K/9.
Vasquez has been one of baseball's elite finishers since 2017 and isn't scheduled to become a free agent until at least 2022; his contract has team options for 2022 and 2023 at $10 million apiece.
Vazquez's stats, 2017-19
The Dodgers' bullpen, considered one of the National League's best entering 2019, owns the fifth-lowest combined ERA (4.23) in the NL. But it ranks near the bottom of the league in K/9 (8.93) and LOB percentage (67.5 percent), according to FanGraphs, and Vazquez is among the NL's best in both categories.
