You tinker with your fantasy squad's starting lineup, looking to have the best possible player at every position.
But did you know that your bench could make the difference between ultimate fantasy success or defeat? For those who have the reserve space, stashing premier prospects or injured big leaguers -- guys who can make a difference tomorrow, if not today -- makes a ton of sense. With that in mind, the 10 players below are worth hoarding for the time being.
Cesar Hernandez, second baseman, Phillies
Prior to landing on the disabled list with a left oblique strain, Hernandez had helped owners in many mixed formats by producing a .277 average and 40 runs scored across 259 plate appearances. Likely to return to the top of the Phillies' lineup in July, the speedy sparkplug can be stashed by those who expect to need a runs and steals boost down the stretch.

Yoan Moncada, second baseman, White Sox
Arguably the best stash option at any position, Moncada could step into the starting second-base job in Chicago by the All-Star break or shortly thereafter. The 22-year-old has the tools to help fantasy owners right away, having hit .282 with 11 homers and 16 steals across 326 plate appearances with Triple-A Charlotte. And though frequent whiffs could limit his batting-average contributions, Moncada may rank among the second-half leaders in stolen bases.

Amed Rosario, shortstop, Mets
The Mets' top prospect, Rosario is hitting .320 with 52 RBIs, 52 runs and 14 steals across 370 plate appearances with Triple-A Las Vegas this season. The 21-year-old natural shortstop could soon find a home atop New York's lineup while also grabbing a permanent spot in an injury-depleted Mets infield. Among all current Minor Leaguers, Rosario ranks behind only Moncada in terms of his potential to make a sizable fantasy impact during the second half.

Yasmany Tomas, outfielder, D-backs
Coming off a 31-homer, 83-RBI season, Tomas got off to a slow start in 2017 -- hitting .241 with eight long balls across his initial 166 at-bats -- before landing on the disabled list with a groin injury. But having recorded 2017 fly-ball and hard-hit rates that are nearly identical to those he produced a year ago, Tomas could be a useful second-half power source once he rejoins a D-backs lineup that ranks fifth in baseball with 435 runs scored.

Jayson Werth, outfielder, Nationals
Werth had become a useful option in deep formats prior to landing on the disabled list June 5, as he was reaching base often and flashing some power as the regular No. 2 hitter in a productive Nationals lineup. Wise owners will stash him away with the hope that he will return to the active roster shortly after the All-Star break.

Ozzie Albies, infielder, Braves
Albies is excelling of late in Triple-A, producing three homers, three steals and a .396 average since June 24. And with the Braves fairly far from the Nats in the National League East, the club may open a spot for its top prospect by trading veteran second baseman Brandon Phillips to a contending team. Once he arrives, Albies (80 steals since the outset of 2015) could immediately become a plus speed source.

Matthew Shoemaker, starter, Angels
Shoemaker struggled badly with the long ball before landing on the disabled list with a right forearm strain, allowing 15 homers across 77 2/3 innings (1.7 HR/9 rate). However, owners with DL space could grab the right-hander and hope that he can rediscover the form that resulted in a 2.83 ERA and a 1.08 WHIP across his final 20 outings last year.

Tyler Glasnow, starter, Pirates
While Glasnow has struggled during his big league opportunities (6.49 ERA, 1.79 WHIP), he should not fall off the fantasy radar. After all, the right-hander owns impressive lifetime statistics (2.03 ERA, 11.8 K/9 rate) in the Minors and has logged a 1.90 ERA with an eye-popping 16.0 K/9 rate across four starts in Triple-A since being demoted June 10. With a fresh chance from the Bucs in the second half, Glasnow could make a major impact in the strikeouts category.

Nate Karns, SP/RP, Royals
Karns has been surprisingly stellar out of the rotation this season, posting a 3.43 ERA, a 1.12 WHIP and a 9.9 K/9 rate across eight starts. Owners who need a pitching boost should be pleased to stash the right-hander, who has returned to throwing and hopes to return in late July.

Keone Kela, reliever, Rangers
Kela has thus far missed his opportunity to grab save chances, landing on the disabled list with right shoulder soreness shortly after Matt Bush was removed from the closer's role. But with a 2.64 ERA, a 0.88 WHIP and a 12.3 K/9 rate this season, the right-hander has been arguably the best reliever in a Texas bullpen that could still be without an unquestioned stopper when he returns to the active roster.
