Catchers (2): Cameron Rupp will be the Opening Day catcher, and Andrew Knapp is the early leader for the backup job. But non-roster invitees Ryan Hanigan and Bryan Holaday will make things interesting because of their experience. Manager Pete Mackanin has said a few times he would like a veteran backup catcher.
Second base (1): Cesar Hernandez. Can Hernandez replicate the success he had this past season, when he ranked 22nd in baseball with a .371 on-base percentage?
Third base (1): Maikel Franco. It's time for Franco to shine. He has All-Star potential, and he needs to show it.
Shortstop (1): Freddy Galvis. His 20 homers were nice, but his .274 on-base percentage ranked last in baseball. If that does not improve and J.P. Crawford plays well early in Triple-A, Galvis' job will be in jeopardy.
Utility infielders (2): Andres Blanco is a no-brainer, but the final bench job is tough to figure out. Brock Stassi, who is a non-roster invitee, is the early choice because he is a stellar defensive first baseman, hits left-handed, knows how to get on base and has some pop. He could be a bench player in the mold of Greg Dobbs and Ross Gload.
Bullpen (7): Left-handers Sean Burnett and Joely Rodriguez and right-handers Joaquin Benoit, Jeanmar Gomez, Hector Neris, Pat Neshek and Edubray Ramos. The five right-handers are safe bets, if healthy. The lefties? Not so much. Burnett has had two Tommy John surgeries, but if he shows enough promise in spring, he makes a lot of sense for a team without many left-handed options. Mackanin knows him and likes him. But left-hander Adam Morgan could earn the final spot in the bullpen over Rodriguez, because he would be another lefty -- and he could be the long man. Mackanin said in January that Morgan could move to the bullpen.
