San Francisco Giants right fielder Lee Jung-hoo hits as single in the seventh inning of the MLB game between the San Francisco Giants and the Milwaukee Brewers at American Family Field in Milwaukee, Wisconsin, June 4. UPI-Yonhap

Lee Jung-hoo of the San Francisco Giants is on a heater.

The Korean outfielder batted 4-for-5 with an RBI and scored three times, as the Giants defeated the Milwaukee Brewers 12-9 at American Family Field in Milwaukee, Wisconsin, on Thursday (local time).

With the four-hit effort, Lee set a new career high with his 12-game hitting streak. This was his fourth game of the season in which he recorded at least four hits, and three of those games have come in the past seven days.

Since returning from the 10-day injured list last Friday, Lee has batted 19-for-29 to raise his batting average from .268 to .322. With evening games still to be played across Major League Baseball (MLB), Lee ranked fourth overall in the big leagues in batting average.
