White Sox have roster battles in bullpen

CHICAGO -- Luis Robert Jr. hit a game-winning grand slam. Eloy Jiménez homered in back-to-back March at-bats, including a two-run blast against the Cubs in Mesa, Ariz. Right-hander Michael Kopech reinforced the point of being close to Major League-ready.
But those top-ranked White Sox prospects are more part of the franchise's exciting future than the present, beginning this campaign in the Minors. Here's a look at how the White Sox 2018 Opening Day roster could shape up.

Catcher (2): Welington Castillo, Omar Narváez
Castillo has spent Spring Training learning about and working with the pitchers, entrenching himself as the No. 1 behind the plate. The backup spot remains a tossup between Narvaez and Kevan Smith, with the left-handed-hitting Narvaez still holding the edge.
First base (1): José Abreu
Here's something qualifying as less than a stunner. Abreu will start at first base for the White Sox and continue to perform as one of the game's steadier middle-of-the-order presences as well as a clubhouse leader.

Second base (1): Yoán Moncada
Moncada started Spring Training in a 1-for-16 funk, not that great Cactus League statistics portend a Hall of Fame career. But Moncada was 6-for-16 over his past five games entering Tuesday's off-day, and he seems to have settled atop the lineup.
Shortstop (1): Tim Anderson
Anderson looks to be enjoying pretty much every moment of Spring Training. That aspect is good to see for a player who dealt with a tough personal loss in 2017. He's also one season removed from his six-year, $25 million extension, and he now has the ability to settle in and play.

Third base (1): Yolmer Sánchez
Matt Davidson has produced stellar Cactus League results and will get a fair share of time at third base. Sanchez, the original life of the party in the White Sox clubhouse, had a breakout season in 2017 and figures to build on that in '18. The club is more than comfortable with this duo at third this season over any outside option.
Outfield (3): Nicky Delmonico, Adam Engel, Avisaíl García
Engel and Ryan Cordell turned in strong Cactus League performances, but Engel established himself as a Gold Glove Award-caliber defensive player at the big league level in 2017 and retained the starting center-field spot. Delmonico also figures to see time at DH, with Leury García available to play the outfield.

Utility/designated hitter (3): Davidson (DH), Leury García, Saladino
Matt Skole was reassigned to Minor League camp on Friday despite making his presence known with two homers, nine RBIs and a 1.054 OPS this spring. But Saladino and Leury Garcia provide more flexibility defensively.
Rotation (5):James Shields, Lucas Giolito, Reynaldo López, Miguel González, Carson Fulmer
Fulmer overcame a shaky Spring Training with four no-hit innings in his last outing. But it looks as though the White Sox aren't moving Fulmer from the starting five, although they have Héctor Santiago waiting in the bullpen in long relief.

Bullpen (8):Nate Jones, Joakim Soria, Luis Avilán, Santiago, Juan Minaya, Gregory Infante, Danny Farquhar, Aaron Bummer
Santiago, a southpaw, will play a valuable part on this staff. If the White Sox intend to go with three southpaw relievers, then Aaron Bummer has made the team, with left-handers Robbie Ross Jr. and Xavier Cedeño being reassigned Friday. Those moves leave right-handers Gregory Infante, Danny Farquhar, Jeanmar Gómez and Bruce Rondón competing for two spots.
