Red Sox first baseman Triston Casas and outfielder Masataka Yoshida respectively finished third and sixth in 2023 American League Rookie of the Year voting. The results were revealed by the Baseball Writers’ Association of America on MLB Network earlier Monday evening.
Casas placed third behind Orioles infielder Gunnar Henderson — who won the award unanimously after securing all 30 first-place votes — and Guardians right-hander Tanner Bibee by receiving six second-place votes and seven third-place votes for a total of 25 points. Yoshida, meanwhile, placed sixth behind Rangers third baseman Josh Jung and Astros catcher Yainer Diaz by netting three third-place votes for three points. Twins second baseman Edouard Julien (two points) and Yankees shortstop Anthony Volpe (one point) rounded out the ballot.
Casas, who last week became the first Red Sox player since Andrew Benintendi in 2017 to be recognized as a Rookie of the Year finalist, put together a strong first full season in the major-leagues after not initially getting off to the best of starts.
Having first debuted at the big-league level last September, Casas unsurprisingly made Boston’s Opening Day roster out of spring training this past March. But the former first-round pick-turned-top prospect struggled at the plate out of the gate and, by the end of April, found himself batting just .133/.283/.293 with three home runs and eight RBIs through his first 25 games of the year.
Despite those early struggles, the Red Sox stuck with Casas, who then rewarded the club for doing so by turning a corner offensively. As the calendar flipped from April to May, the 23-year-old slugger steadily raised his OPS and, after a solid showing in June, broke out to the tune of a ridiculous .349/.442/.758 slash line with seven home runs and 13 RBIs in 21 July contests to take home American League Rookie of the Month honors.
Even as the Red Sox began to fall out of contention in the AL East over the summer, Casas remained a force to be reckoned with in the batter’s box. From August 1 through September 13, the left-handed hitter batted .284/.389/.508 with eight home runs and 25 RBIs in 39 games. He then missed the final two-plus weeks of the season after being shut down with right shoulder inflammation.
Still, despite the disappointing finish, Casas managed to forge one of the more impressive Red Sox rookie seasons in recent memory by slashing a stout .263/.367/.490 with 21 doubles, two triples, 24 home runs, 65 RBIs, 66 runs scored, 70 walks, and 126 strikeouts over 132 total games (502 plate appearances). Altogether, he led Boston in walks, on-base percentage, and OPS (.856) while finishing second in homers and fourth in runs driven in.
Among qualified rookies in the junior circuit this season, Casas ranked second in homers, fourth in RBIs, fourth in runs scored, second in walks, seventh in batting average, third in on-base percentage, fourth in slugging percentage, second in OPS, fifth in isolated power (.226) and third in walk rate (13.9 percent), per MLB.com’s leaderboards.
On the other side of the ball, all but two of Casas’ 117 starts this year came at first base. The burly 6-foot-5, 244-pounder committed only five errors in 958 chances while logging 1,037 innings at first. In spite of the high fielding percentage, though, Casas graded poorly in other areas such as defensive runs saved (-4) and outs above average (-10). That likely did not help his case when it came to award voting.
Regardless of the defensive metrics, the 2023 campaign still served as an important stepping stone for Casas in which he established himself as the Red Sox’ first baseman of the future. To that end, Casas — who turns 24 in January — is a prime candidate for a pre-arbitration contract extension depending on how things shake out for Boston this winter.
Yoshida, on the other hand, spent the first seven years of his professional career in Japan before signing a five-year, $90 million contract with the Red Sox in December. As a major-league rookie this season, the left-handed hitting 30-year-old batted .289/.338/.445 with 33 doubles, three triples, 15 home runs, 72 RBIs, 71 runs scored, eight stolen bases, 34 walks, and 81 strikeouts in 140 games spanning 580 trips to the plate.
