Dodgers acquire Josh Fields from Astros for Yordan Alvarez

LOS ANGELES -- The third and final deal for the Dodgers on the day of baseball's non-waiver trade deadline, acquiring relief pitcher Josh Fields from the Astros in exchange for minor league first baseman Yordan Alvarez.

Fields, who turns 31 on Aug. 19, has a 6.89 ERA in 15 relief appearances this season for Houston, but also has a 2.81 FIP thanks to 20 strikeouts and only three walks in 15⅔ innings.

He has been in the minors since mid-May, putting up a 1.65 ERA and 2.21 FIP in 23 games for Triple-A Fresno, with 32 strikeouts and seven walks in 27⅔ innings. Fields has a 29.2-percent strikeout rate between the majors and minors thie year.

Fields in 2015 had a 32-percent strikeout rate and a 3.55 ERA in 54 major league games.

He is making $900,000 this season, with roughly $304,918 remaining. He entered the 2016 with three years of service time, and is using his second option year this season. He will have one more option year remaining after 2016.

Alvarez, 19, was signed by the Dodgers out of Cuba on June 15, the final day of the 2015-2016 international signing period, for a reported $2 million, which also came with a $2 million overage penalty.

To make room for Fields on the 40-man roster, the Dodgers transferred Hyun-jin Ryu to the 60-day disabled list, with left elbow tendonitis. Technically, he cannot be activated before Sept. 6.
