Players who could become first-time MLB All-Stars

Alonso has taken the league by storm in his rookie season and is a top candidate for NL Rookie of the Year. The big first baseman was hitting .263-19-44 through 58 games for the Mets.

Anderson's celebrations rub some the wrong way, but he's clearly emerged as one of the most exciting players in the game. He became a 20/20 man last year but has added batting average to his arsenal this year, hitting .330-9-28 with 14 stolen bases in 52 games.

Coming off a down year, Bell is a legitimate NL Triple Crown candidate in his third full season. He was hitting .332-18-53 with a league-leading 21 doubles over 58 games after an incredible month of May.

Boyd has suddenly become a strikeout machine this season, with 97 strikeouts in 77.2 innings. He also sports a 3.01 ERA and 1.017 WHIP through 12 starts.

Castillo has put his name at the head of the Cy Young race in the National League with his amazing start. He's 5-1 with a 2.45 ERA in 12 starts over 69.2 innings, proving to be nearly unhittable in most of his outings.

Chapman had started to become a household name after his brilliant 2018 season, and he hasn't slowed down this year. The 2018 AL Gold Glove winner at third base is hitting .272-16-35 with a .914 OPS in 59 games.

DeJong has been arguably the best player on a Cardinals team loaded with names. Through 58 games, he's hit .276-8-26 with a .853 OPS, seeing a major uptick in walks.

Dietrich is just the newest former Marlins hitter to prosper after leaving Miami. Through 56 games, he already has a career-high 17 home runs and an elite 1.073 OPS while playing all over the field for the Reds.

Hitting in the majors was a struggle for Dozier last year, but he's turned a corner this season. Now Kansas City's regular third baseman, he's hitting .314-11-33 with a .987 OPS in only 52 games.

Gallo was an elite power hitter over the last two seasons with a combined 81 home runs, but his batting average was sub-.210. That's changed this year, as Gallo is hitting .276-17-41 with a 1.074 OPS, second in the AL, in 50 games while playing an adequate center field.

Coming off a sub-par 2018 season between Houston and Toronto, Giles has successfully rebounded as one of the game's top closers this year. He has a 1.19 ERA and 37/5 K/BB in 22.2 innings with 10 saves.

Greene converted 32 saves despite an ERA above 5.00 last year, but he's been an elite closer this season for the Tigers. He currently has a 1.13 ERA and AL-leading 18 saves.

Moving from Detroit to the White Sox this offseason, McCann was expected to be Welington Castillo's backup in his new home. He forced the White Sox hand with his bat, hitting .338-4-12 with a .907 OPS through 38 games.

Tampa Bay's return in last year's Chris Archer trade has been quite profitable with the performances of Meadows and Tyler Glasnow. Despite battling injuries, Meadows has been an elite player for the Rays, hitting .357-12-37 with seven stolen bases and a 1.085 OPS in only 41 games.

Minor is in the AL Cy Young conversation for what he's done through 12 starts. The lefty is 5-4 with a 2.74 ERA and 80/24 K/BB in 75.2 innings. He had good seasons for Atlanta and Kansas City in the past but never sniffed the All-Star Game.

Odorizzi struggled in his first season with the Twins, in 2018, but he has turned a corner this year. He has an AL-best 1.96 ERA through 12 starts with eight wins. He also sports a 0.964 WHIP and 70 strikeouts through 64.1 innings.

Paddack surprisingly made the Padres out of spring training, and he hasn't looked back. Through 10 starts, Paddack is 4-3 with a 2.40 ERA and 62/12 K/BB in 56.1 innings. His 0.82 WHIP is perhaps his most impressive statistic, as he stands as the current NL Rookie of the Year front-runner.

Pham looks well on his way to his third consecutive 20 home run season, starting the year hitting .305-8-26 with six steals in 53 games. A strong increase in walks (38) has also helped him produce an elite .418 on-base percentage.

Polanco currently is second in the AL with a .338 batting average and 74 hits through 55 games. The budding star shortstop also has a strong nine home runs and 30 RBI over that time, with a .989 OPS.

Rosario has had an argument for the All-Star Game over the last two years, but the third time could be a charm. He is tied for second in the AL with 17 home runs through 56 games and is also among the league leaders with 49 RBI and 40 runs scored.

It would be quite an upset if Ryu fails to get an All-Star nod after his start to the year. He finished last season with a 1.97 ERA in 15 starts and has shown that performance wasn't a fluke by going 8-1 with a 1.48 ERA through his first 11 starts this season. The lefty has walked only five batters through 73 innings.

The Giants bullpen has been their strength, and Smith has led the way. The lefty has a 2.38 ERA, 13 saves, and 32/4 K/BB through 22.2 innings.

While Stroman is one of the faces of baseball, he never made an All-Star Game through his first five seasons. That could change this year, as the Jays ace has a 2.84 ERA through 13 starts over 76 innings.

An exemplary minor league hitter, Vogelbach never performed in the majors until this season. He's been a big basher for the Mariners with 15 home runs and a .922 OPS in 53 games.

Yates was promoted to closer last year after the Padres traded Brad Hand, and he's run with the role since then. He leads the league with 22 saves, adding a 1.04 ERA and 45/8 K/BB in 26 innings.
