Grichuk was drafted by the Los Angeles Angels of Anaheim in the first round of the 2009 Major League Baseball Draft from Lamar Consolidated High School in Rosenberg, Texas. He played five seasons in the Angels' minor leagues system, losing time to injury but also developing home-run hitting ability throughout before the Angels traded him to the St. Louis Cardinals in November 2013, with whom he made his major league debut on April 28, 2014. He spent four seasons with the Cardinals before he was traded to the Blue Jays prior to the 2018 season. After four seasons with Toronto, he was traded to the Rockies, then traded to the Angels at the 2023 trade deadline, where he was originally drafted.
Grichuk attended Lamar Consolidated High School in Rosenberg, Texas. In 2008, as a Lamar Consolidated Baseball player, he was a First Team All-State OF and the All-Houston Area Most Valuable Player (MVP). That season, Grichuk batted .435 with 18 home runs and 45 RBI, leading the Mustangs to a school record 29 wins and a Regional Final appearance. In 2009, he was the 24-4A District MVP, Fort Bend Area MVP, 2009 1st Team All State OF, and 2009 1st Team All-American (EA Sports and Baseball America). In 28 games he hit .613 with 21 home runs, 46 hits, 46 RBI and 47 runs before Lamar was defeated in the third round of the playoffs.
A series of three unusual injuries delayed the outfield prospect's development. First, he tore a ligament after just 12 games in 2010. Second, he batted a foul ball that fractured his knee cap. Finally, while diving for a ball, he broke his wrist. In 2012, his first full season, Grichuk played 135 games and batted .298 with 18 home runs and 71 runs batted in with the Class-A Inland Empire 66ers. After a promotion to the Double-A Arkansas Travelers in 2013, he made 128 appearances, batting .256 with 22 home runs and 64 RBI.[6] In October 2013, Rawlings and MiLB announced Grichuk was the recipient of the Minor League Gold Glove Award for right field.[7]
The Cardinals promoted Grichuk to the majors for the first time on April 28, 2014, after he had slashed .310/.359/.529 with six walks and 17 strikeouts.[11] He debuted as a defensive replacement in the outfield that day. Grichuk made his first major league start in center field the next day, collecting a single in five at-bats for his first major league hit.[12] The Cardinals optioned him back to Memphis shortly thereafter. On May 21, he showed the authorities what he could do with a big game-winning home run versus the Colorado Springs Sky Sox, giving an anonymous fan an autograph after the game. Shortly afterwards, the Cardinals recalled him to the big leagues on May 30. He improved his AAA numbers, slashing .315/.363/.589 with ten home runs.[13] Grichuk received the Cardinals' minor league system Player of the Month Award for May 2014.[14] On June 7, he hit his first major league home run off Toronto Blue Jays' starter Mark Buehrle in a 5–0 victory.[15]
Grichuk produced a .944 on-base plus slugging percentage (OPS) in 44 spring training at bats in 2015 and made the major league club as a fifth outfielder.[16] While lifting weights, he strained his lower back, halting his play on April 16 and prompting the Cardinals to place him on the 15-day DL.[17] On May 16, the Cardinals activated him from the disabled list.[18] After striking out five times on May 18, he followed up with two doubles and a triple the next night against the New York Mets, as the Cardinals prevailed 10–2.[19]
When Matt Holliday went on the DL in early June, that opened Grichuk's first legitimate opportunity for regular playing time in the major leagues, including all three outfield positions.[16] From June 19–20 against the Philadelphia Phillies, he forged consecutive three-hit games, including hitting a home run in the first game, then two in the second.[20] On June 30, he was a double short of hitting for the cycle in a 2–1 loss to the Chicago White Sox. His home run off Chris Sale traveled 448 feet (137 m), however, and landed in the Big Mac Land section of Busch Stadium. Through that point in the season, it was the longest home run of the year there by a Cardinals player.[21]
Setting a new career high with six runs batted in on July 18, Grichuk also homered twice in a 12–2 win over the Mets.[22] On August 5 against the Cincinnati Reds, he doubled in the sixth inning and hit the game-winning home run in the top of the 13th at Great American Ball Park in a 4–3 game.[23] After straining his right elbow, the Cardinals placed Grichuk on the disabled list on August 17.[24] The Cardinals reactivated him less than one month later. On September 10, he played center field against the Chicago Cubs, but was not permitted to throw as his elbow had still not fully recovered.[25] After the season, he underwent surgery to repair a sports hernia.[26]
2016−17
Out of spring training in 2016, Grichuk won the role as starting center fielder.[27] He hit his first career walk-off home run on May 23 in a 4–3 win against the Cubs.[28] With his overall offensive output in decline from the previous year, the Cardinals optioned him to, and recalled him from, Memphis on multiple occasions in 2016.[29] On August 13, 2016 − his 25th birthday − Grichuk hit his first career grand slam, providing the margin in an 8−4 win over the Cubs, and ending their 11-game win streak.[30] He produced the game-winning RBI double on August 19 against Philadelphia Phillies in the 11th inning of a 4−3 win.[31] Grichuk ended 2016 with a .240 batting average along with 24 home runs and 48 RBIs.[32]
On January 19, 2018, the Cardinals traded Grichuk to the Toronto Blue Jays in exchange for pitchers Dominic Leone and Conner Greene.[34] He began the season as Toronto's starting right fielder. On March 30, Grichuk hit his first home run as a Blue Jay, which came on the first pitch he saw from Masahiro Tanaka in the second inning of a 4–2 loss to the New York Yankees.[35] After batting only .106 with two home runs and seven RBIs in 25 games, he was placed on the disabled list with a right knee strain on April 30.[36] He was activated on June 1.[37] Grichuk finished the season batting .245/.301/.502 and tied for first on the team in home runs with Justin Smoak with 25.
On April 2, 2019, Grichuk and the Blue Jays agreed to a five-year contract extension worth $52 million.[38] In 2019, he led the team in both home runs (31) and runs batted in (80) despite hitting .232/.280/.457.[39]
With the 2020 Blue Jays, Grichuk batted .273 with 12 home runs and 35 RBIs in 55 games.
In 2022 he had the lowest BB/K% in the NL (0.19), the lowest line drive percentage of all qualified major league batters (12.9%), and batted .259/.299/.425.[41][42] On the 2023 season, Grichuk's offensive production dipped despite hitting .308 in 64 games before being traded.
Los Angeles Angels
On July 30, 2023, Grichuk was traded to the Los Angeles Angels along with C. J. Cron in exchange for minor league pitchers Jake Madden and Mason Albright.[43][44] Grichuk was placed on waivers by the Angels on August 29, but was not claimed and remained with the club.[45] On September 6, Grichuk was again placed on waivers by the Angels.[46]
Arizona Diamondbacks
On February 17, 2024, Grichuk signed a one-year, $2 million contract with the Arizona Diamondbacks.[47] He declined his share of a mutual option for the 2025 season on October 31, and became a free agent.[48]
In 2014, Randal Grichuk was projected with potential as a power hitter in the major leagues possessing the athleticism and preparedness to handle center field well. At the plate, his most evident ability is to hit the ball with power and loft to all fields, easily give him potential for 20 or more home runs a season. With a smooth and compact stroke, his bat speed through the zone is at least average and frequently faster. His pitch recognition allows him the ability to work counts and he becomes more aggressive in hitter's counts. This approach yields lower-than-average walk rates but with a strikeout rate of less than 20 percent. One obvious weakness is that he misses easy pitches – such as high fastballs in the middle of the plate – that major league hitters rarely miss.[51]
According to Baseball America's Kary Booher, Grichuk possesses an athletic frame with average arm and enough range to profile into an outfield corner slot. Through 2013, he has shown a low walk rate but has enough balance and bat control to bat .260 or higher in the major leagues.[52]
Grichuk drew widespread attention for his raw power and bat speed in 2015. As of August 11, 2015, the average exit velocity of all his batted balls on the season was seventh in the major leagues at 93.17 miles per hour (149.94 km/h). The average for all fly balls and line drives only was fourth at 97.79 miles per hour (157.38 km/h).[53]
Originally projected to be a first baseman, Grichuk expanded his versatility to the outfield thanks in part to extra preparation and a sleek and proportioned athletic frame. For what he lacks in the classic speed of center fielders, he mitigates with robust jumps and precise route running and positioning to easily anticipate the trajectory of – and catch – balls hit to the outfield. His arm strength and range allow him the ability to cut off runners at times from extra bases on the occasional plays for which he did not properly position himself.[51]
