2. RP MATT BARNES

There was an interesting trade between the Miami Marlins and the Boston Red Sox earlier during the off-season. It wasn't as historic as another trade between these two teams... The Miami Marlins acquired relief pitcher Matt Barnes. Matt Barnes is a high risk high reward reliever who can either be the next Miami Marlins closer or a frustrating reliever who you're wondering why he's pitching in late innings at all.

Matt Barnes is a high risk high reward relief pitcher for the Miami Marlins.

Matt Barnes is 32 years old and is a right-handed relief pitcher. Barnes debuted in the Major Leagues in 2014 with the Boston Red Sox.

It's clear that the strikeout rate and FIP are impressive, but the walk rate and ERA are not. He currently has a 4.91 ERA in Spring Training. I'm concerned that he will blow leads and do more harm than good if he can't get his walks under con
