One player holds steady and another makes a huge leap in the top two spots of our newest Rookie Power Rankings.

The RPR, as voted on by the staff of MLB Pipeline, is a reflection of how we think the Rookie of the Year voting will play out at the end of the year, using a combination of performance and what we think will happen for the rest of the season. Marlins lefty Trevor Rogers is still our No. 1, despite having missed time, while Reds infielder Jonathan India has vaulted past others to claim the second spot as his big second half continues. With more than a month and half to go, there’s still plenty of time for players to continue to perform their way up the list or slide off of it.

1. Trevor Rogers, LHP, Marlins
Previous RPR: 1
Back spasms that landed him on the injured list in July and he’s now on the bereavement list, but he’s built enough resume to hold on to the top spot for the sixth straight edition. The lefty still leads all qualified rookies in ERA (2.45) and is tied for the lead in strikeouts (129).

2. Jonathan India, 2B, Reds
Previous RPR: 10
India jumps up the list thanks to a July that earned him National League Rookie of the Month honors (.319/.470/.527 slash line with four homers and 12 RBIs over 25 games). He’s added three homers in nine August games to date and he’s now second among all qualified rookies with his .853 OPS, while leading with a .399 OBP for the year and standing fourth with 48 RBIs.

T3. Randy Arozarena, OF, Rays
Previous RPR: 5
Arozarena must smell the postseason coming, as he’s hit .362/.413/.739 with six homers in 18 games since the All-Star break. He now has 16 homers and 11 steals on the year and is in the top five among rookies in a host of offensive categories, including home runs, RBIs, stolen bases, OBP and OPS.

T3. Luis Garcia, RHP, Astros
Previous RPR: 3
Garcia is now tied with Rogers for the rookie strikeout lead (129) to go along with his 3.29 ERA and .213 batting average against. He had back-to-back rough outings on July 26 and Aug. 1, but bounced back with six shutout innings on Aug. 7, a start that saw him yield just two hits and no walks while striking out eight.

5. Adolis García, OF, Rangers
Previous RPR: 2
García’s second-half slide is why he’s down to the No. 5 spot on the rankings. While he still leads all rookies in homers (25) and RBIs (68) and his third in SLG (.490), the outfielder has produced just a .173/.230/.346 slash line since the All-Star break, with just three homers and six RBIs in 22 games

6. Andrew Vaughn, OF, White Sox
Previous RPR: 6
After jumping back on the rankings for the first time since May in our last edition, Vaughn has held steady as he’s continued to swing the bat well in the second half. The 2019 No. 3 overall pick now has a .301/.378/.479 line since the break and has been even hotter in six August contests (.368/.500/.684).

7. Emmanuel Clase, RHP, Indians
Previous RPR: 7
After a small bump in the road in July, when he blew three straight saves, Clase has now recorded saves in his last five opportunities to give him 16 for the year. He also hasn’t allowed a run since his last blown save, a stretch of 10 outings and 10 1/3 innings, lowering his ERA to 1.71 and his batting average against to .220.

T8. Dylan Carlson, OF, Cardinals
Previous RPR: 4
Carlson has been good, but not great, for most of the 2021 season, with a respectable .260/.340/.421 line with 12 homers and 46 RBIs, tied for fifth among all rookies in that last category. Keep an eye on him, though, as he’s off to a very good start in August (.375/.417/.563 in eight games). If that continues, he could make a beeline back up this list.

T8. Ryan Mountcastle, 1B/OF, Orioles
Previous RPR: unranked
Mountcastle has posted a .308/.324/.615 line since the break, thanks to a white-hot start to his August (.563/.529/1.125 in five games). He’s second among rookies in homers (19) and RBIs (63), with the chance to catch García in both categories if he keeps swinging the bat like this.

10. Ian Anderson, RHP, Braves
Previous RPR: 8
Anderson is still on the mend from shoulder inflammation that’s kept him out of big league action since July 11. He’s made one rehab outing to date, with time for him to come back and help his 3.56 ERA (fourth among qualified rookies) and .226 BAA (sixth).

Also receiving votes: Akil Baddoo, OF, Tigers; Casey Mize, RHP, Tigers (Previous RPR: 9); Logan Gilbert, RHP, Mariners
