Ahead of Sunday's first day of Major League Baseball's international signing period, the Red Sox acquired bonus pool space from the Reds in exchange for one of their top prospects, Nick Longhi.
Ranked the club's No. 9 prospect, per MLBPipeline.com, Longhi was batting .262 with 15 doubles, six homers and 33 RBIs in 62 games for Double-A Portland, where he's spent the entire season.
Drafted in the 30th round in 2013, Longhi participated this spring in big league camp. Over 347 Minor League games, the 21-year-old has hit .278 with 16 homers and a .738 OPS, mostly starting at first with occasional stints at the corner-outfield spots.
Red Sox deal Minor Leaguers to Cards
The Cardinals announced Sunday they've traded international cap space to the Red Sox in exchange for Minor League infielders Stanley Espinal and Imeldo Diaz.
Espinal, 20, was signed in February 2015 as an amateur free agent out of the Dominican Republic. In 132 career games, he's batted .251 with eight homers and 82 RBIs. At 6-foot-2, 190 pounds, the right-handed hitter has played primarily at third base, and led the Dominican Summer League in RBIs in 2015, with 59.
Diaz, 19, has compiled a .222 clip in 123 Minor League games, and was signed by Boston on this day three years ago out of Venezuela.
