The first baseman job had a big question mark surrounding it even after the Miami Marlins signed Garrett Jones in the offseason. Jones is a left-handed batter who barely touches balls thrown to him by lefty pitchers. The Marlins knew they would need a platoon at first and in some aspects it has helped.
Even with the platoon at some points during the season, Jones has still managed to play in 89 games for the Marlins. Jones is hitting .253/.321/.423 with 10 home runs and 37 RBIs. He is on pace to have a better season than he did with the Pittsburgh Pirates in 2013 and already proving that he can become the full-time starter at first for Miami.
The problem with Jones is his aforementioned struggles against left-handed pitching. Jones is batting .190/.242/.224 with 11 hits and two RBIs in 62 plate appearances. It is not helping Jones at all that he struggles, but he is going to have ample opportunity to get it down pat.
Aside from Justin Bour, the Marlins do not have a true first baseman in the farm system to replace Jones. The team’s best bet is Jeff Baker, but even he is having his struggles this year. Jones needs to start getting better against lefties or start really hitting lights out against right-handed pitchers. The remainder of the season awaits for Jones, so hopefully he can improve even more.
