CHICAGO -- The Red Sox will face Michael Kopech, the fireballer they traded with three other players for Chris Sale, on Friday at Guaranteed Rate Field.

Nathan Eovaldi will start for Boston opposite Kopech who is 1-0 with a 1.13 ERA, (8 innings, one earned run) and 1.25 WHIP in two major league starts.

Kopech's debut was shortened to 2 innings because of rain. He hasn't allowed a walk and has struck out eight. He has thrown 70 percent strikes.

Kopech has thrown 96 four-seam fastballs, 33 sliders and nine changeups. So he has used his fastball 69.6 percent of the time, the slider 23.9 percent of the time and the changeup just 6.5 percent, per Baseball Savant. That said, he primarily is a fastball-slider pitcher at this point of his career.

His fastball has averaged 95.9 mph and topped out at 98.5 mph. He topped out at 98.5 mph in both starts.

Moncada has .695 OPS

Yoan Moncada, the other big-name prospect sent to Chicago in the Sale trade, is slashing .220/.302/.393/.695 with 16 homers, 23 doubles, six triples and 53 RBIs in 123 games (539 plate appearances).

He leads all major leaguers with 184 strikeouts. He has a disappointing .196/ .288/.359/.647 line in August.

Basabe and Diaz updates

The Red Sox also traded Luis Alexander Basabe and Victor Diaz to the White Sox.

Basabe, a 22-year-old center fielder from Venezuela, has a .258/.343/.406/.748 line with six homers, eight doubles, three triples and 26 RBIs in 57 games (253 plate appearances) at Double-A Birmingham.

The 24-year-old Diaz, a righty from the Dominican Republic, hasn't pitched in any minor league games this year because of a shoulder issue. He allowed 19 earned runs in 12 innings at Low A and High A last year.
