The AL Rookie of the Year Race Is as Interesting as Ever

When Major League Baseball and the Major League Baseball Players Association signed a new Collective Bargaining Agreement this offseason, it included some interesting provisions designed to combat service time manipulation. Top prospects who finish first or second in Rookie of the Year voting will automatically gain a full year of service time regardless of when they’re called up, and teams that promote top prospects early enough for them to gain a full year of service will be eligible to earn extra draft picks if those players go on to finish in the top three in Rookie of the Year voting or the top five in MVP or Cy Young voting. The goal was to incentivize teams to call up their best young players when they’re ready, rather than keeping them in the minor leagues to gain an extra year of team control.
So far, the rule changes seem to have had their intended effect: three of our top five preseason prospects, and 11 of our top 50, earned an Opening Day roster spot out of spring training. The three prospects in the top five all play for American League teams, and with many others putting together impressive performances in the majors, the competition in the junior circuit for the Rookie of the Year award is quite compelling. Below is a table of the best rookie performers in the AL through June 15:
Player | Team | PA | wRC+ | OAA | WAR |
---|---|---|---|---|---|
Jeremy Peña | HOU | 211 | 133 | 6 | 2.5 |
Julio Rodríguez | SEA | 255 | 122 | 5 | 1.8 |
Bobby Witt Jr. | KCR | 246 | 106 | 2 | 1.6 |
Steven Kwan | CLE | 185 | 113 | 0 | 0.8 |
Jake Burger | CWS | 144 | 135 | -3 | 0.7 |
MJ Melendez | KCR | 146 | 123 | 1 | 0.5 |
Adley Rutschman | BAL | 86 | 69 | — | 0.2 |
Spencer Torkelson | DET | 199 | 67 | -1 | -0.8 |
Player | Team | IP | ERA | FIP | WAR |
Joe Ryan | MIN | 48 | 2.81 | 3.75 | 0.9 |
Jhoan Duran | MIN | 28.2 | 2.51 | 3.00 | 0.4 |
George Kirby | SEA | 43 | 3.56 | 4.07 | 0.4 |
Reid Detmers | LAA | 53 | 4.25 | 5.16 | 0.1 |
Jeremy Peña (ranked 30th on our preseason Top 100) has raced out ahead of the three top prospects referenced above to accumulate 2.5 WAR in just 54 games. That mark is the second highest among AL shortstops, and is the result of his phenomenal up-the-middle defense and his prowess at the plate. He’s slashed .277/.333/.471 (133 wRC+) so far this year with a solid if aggressive approach and some good power. The thump is a recent development after Peña filled out last year. He’s already blasted nine home runs and his peripherals support a profile that could reach 20 homers by the end of the season; his max exit velocity and barrel rate both sit above league average, with only his hard hit rate falling below.
