The Boston Red Sox acquired Chris Sale, one of the game's most dominant left-handed pitchers, from the Chicago White Sox for Yoan Moncada and three other prospects.

The White Sox also got minor league right-handed pitchers Michael Kopech and Victor Diaz and outfielder Luis Alexander Basabe.

The blockbuster marks a turn toward rebuilding for the White Sox, who deal their left-handed ace whose combination of dominance and cost-effectiveness made him the top prize on the trade market this winter.

The Chris Sale effect: How his trade impacts the Red Sox, White Sox and others

As for the Red Sox, they land Sale, 27, for three years at the low cost of $51.5 million if they exercise a club option for 2019. And suddenly, they boast a deadly left-right-left combo of David Price, Cy Young Award winner Rick Porcello and Sale, who went 17-10 with a 3.34 ERA and 233 strikeouts in 226 2/3 innings last season.

The cost was significant, as club President Dave Dombrowski sent power-hitting Cuban infielder Moncada to the White Sox, along with right-handed starter Michael Kopech, outfielder Luis Basabe and right-hander Victor Diaz.

Top prospects carry most fantasy intrigue in Chris Sale trade

Moncada, 21, produced a .918 OPS in 106 games at high-A and Class AA last season, and then had a 19-at-bat stint in Boston at the end of the year. He was the top-ranked prospect by Baseball America at midseason.

Kopech, 20, was ranked No. 93 on that list, but was limited by hand and calf injuries in 2016. The 33rd overall pick in 2014, Kopech has struck out 172 batters in 134 2/3 career minor league innings.

Dombrowski proved, as he did in helming the Detroit Tigers, that he's not afraid to boldly deal prospects to win now. The Red Sox committed $63 million in February 2015 to sign Moncada - a $31.5 million signing bonus and an overage tax for the portion of their bonus that exceeded their $1.8 million international bonus pool at the time.
