In Wednesday afternoon MLB action, the Chicago Cubs and the Miami Marlins will wrap up their series from loanDepot Park. Be ready for the baseball season with all of our MLB predictions. The Cubs (29-20) have won seven of their last ten games and hold a 1.5 game lead over St. Louis for the top spot in the NL Central Division. Last night, OF Seiya Suzuki collected three of Chicago’s 21 hits and drove in four runs during a 14-1 road triumph. 

Rookie right-hander Cade Horton (2-0 6.00 ERA) will make his second career major league start for the Cubs. In his first start, Horton (5 IP) gave up seven hits and three runs during a 13-3 home victory versus the White Sox. 

The Miami Marlins are a game below .500 at home and are trying to climb out of the NL East Division cellar. During Tuesday’s home loss, Miami’s only run came on a third-inning solo shot from C Nick Fortes. SP RP Calvin Faucher (2-2) surrendered six runs and failed to record an out in a losing effort for the Marlins, who fell to 19-28 overall.
