SAN DIEGO -- The first half of the 2019 season has seen a handful of very good players burst onto the scene from the National League West.

With the All-Star Game fast approaching, there isn't room for all of them -- yet. Some of the division's young stars will have to wait their turn.

Here's a look at five players in the NL West who might not be All-Stars this season, but whose first trip to the Midsummer Classic doesn't seem very far off.

D-backs: RHP Luke Weaver

Weaver really took a step forward this year when he began to incorporate a slider into his mix of pitches. After a rough opening start, he hit his stride before suffering a mild right flexor pronator strain and a mild right UCL sprain during his start against the Giants on May 26.

The injury will likely keep Weaver out until later this season, but if he picks up next year where he left off in 2018, he could find himself at a future Midsummer Classic.

Weaver made 11 starts for Arizona before the injury, posting a 3.03 ERA with 68 strikeouts in 62 1/3 innings and an ERA+ of 148.

Dodgers: OF Alex Verdugo

The NL outfield is loaded with big-name options this season, meaning Verdugo will almost certainly be left out of the festivities. But the exciting rookie will get a few more chances to state his case as an All-Star.

Verdugo was hitting .296/.352/.458 entering play Wednesday and was a crucial piece in the Dodgers' hot start. He appears to be breaking out after his first true slump, which lasted for a few weeks in late May and early June.

Verdugo is only 23, and he was always destined to experience some growing pains. But given his immense talent, it was pretty clear he'd overcome them.

Giants: RHP Reyes Moronta

Moronta enjoyed a breakout season for the Giants last year, logging a 2.49 ERA over 65 innings, and he’s continued to be a key cog in the club’s talented bullpen this season.

With an upper-90s fastball, a sharp slider and a new changeup, Moronta profiles as the Giants’ closer of the future, and he could find himself ascending to the ninth-inning role later this year if the club opts to trade incumbent Will Smith ahead of the Trade Deadline.

Padres: RHP Chris Paddack

There was a time this season when Paddack seemed like a surefire All-Star. He opened the year with nine starts in which he posted a 1.93 ERA, and he owns a 28 percent strikeout rate on the season.

But Paddack's last month probably rules him out. He struggled in three of four starts and saw his ERA jump to 3.15. He was also optioned to the Minors as a chance to limit his workload, and he won't be recalled until Saturday in Pittsburgh, according to sources. A season ago, Paddack threw just 90 innings in his return from Tommy John surgery, and this year, he's already three-quarters of the way there.

So, no, Paddack probably doesn't have the innings to merit All-Star consideration. But based on his early-season performance, he's on the right trajectory.

Rockies: OF David Dahl

Fair or unfair, it takes time for very good hitters to be recognized when they play their home games at Coors Field. Even though Dahl is tearing the cover off the ball this season with a .924 OPS entering Wednesday, it's hard to envision him slotting into a loaded National League outfield this year.

But Dahl is only 25. He figures to be a fixture in Rockies' outfield for years to come. And sooner or later, he'll probably be recognized with a trip to the Midsummer Classic.
