Rocco Daniel Baldelli (; born September 25, 1981) is an American former professional baseball outfielder, coach and manager, who is currently an executive in the baseball operations department of the Los Angeles Dodgers. As a player, Baldelli quickly progressed through the minor leagues and made his Major League Baseball (MLB) debut with the Tampa Bay Devil Rays on opening day in 2003. Baldelli quickly established himself as an excellent hitter and outfielder, and placed third in voting for American League (AL) Rookie of the Year. He also played in MLB for the Boston Red Sox.
In 2005, Baldelli's promising career was derailed by channelopathy, a rare metabolic/muscular disorder which causes frequent soft tissue injuries and severe fatigue. He was unable to play at all in 2005 and missed significant time over the following seasons as doctors struggled to diagnose and treat his condition; from 2005 until his retirement in 2010, the former everyday center fielder spent long stretches on the disabled list and only once appeared in more than half of his team's games. Baldelli signed a free-agent contract with his hometown Red Sox in 2009 and appeared in 62 games as a backup outfielder and part-time designated hitter. Unsure if he was physically capable of continuing his playing career, he returned to the Rays organization as a minor league coach in December 2009. As the 2010 season progressed, he decided to attempt another comeback and began rehabbing in the Rays' minor league system. Baldelli returned to the major leagues in September and hit a pinch-hit home run in his first at-bat. He appeared in 10 games over the last month of the regular season and was included on the Rays' playoff roster, but severe muscle cramping during the team's first round series forced him out of the lineup, at which point he decided to end his playing career at age 29.
After retiring as a player, Baldelli spent three years in the Tampa Bay Rays organization as a roving minor league instructor and special assistant to baseball operations. He was named the club's first base coach before the 2014 season and was promoted to major league field coordinator in November 2017.
Baldelli was named manager of the Minnesota Twins after the 2018 season. In 2019, he led them to 101 wins and an AL Central Division title and was named the 2019 American League manager of the year. At 38 years old, he was the youngest manager to win the award. He remained with the Twins through the 2025 season when he was fired from the position.
Early life Rocco Daniel Baldelli was born to Dan and Michele Baldelli in Woonsocket, Rhode Island.Kimmey, Will. "2002 Minor League Player of the Year." 2002. Baseball America. Electronic. November 26, 2013. Rocco Baldelli attended the PEGASUS Gifted and Talented middle-school program at La Salle Academy in Providence. He played baseball for the Rhode Island Tides, an AAU ball club. Then he switched to Bishop Hendricken High School in Warwick, Rhode Island, for high school. During his senior year at Bishop Hendricken High School, he pulled his oblique muscle, but still managed to hit .531-5-13 with nine steals in only 32 at-bats. Not only did Baldelli excel at sports, but in the classroom as well. There he posted a 4.25 grade point average. On the SAT, he scored 1300, and considered attending University of North Carolina, Wake Forest University, Princeton University and Yale University. He was also a four sport star, earning all-state honors in baseball, indoor track, basketball, and volleyball.
Professional baseball career Minor leagues The Tampa Bay Devil Rays picked Baldelli in the first round (6th overall) of the 2000 Major League Baseball draft, so he decided to decline an athletic scholarship offer from Wake Forest and signed with Tampa Bay for $2.25 million. He began his professional career with the Princeton Devil Rays, the team's High Rookie League affiliate.
Initially, Baldelli had to adjust to professional baseball. Says Baldelli, "In Princeton, I had a hard time with all parts of the game…I didn't know how to play the game. Coming out of high school, I'd just come up to the plate and swing as hard as I could every time and try to smoke the ball. I didn't know about hitting mechanics, breaking pitches or reading pitchers."
Baldelli overcame his struggles as a hitter and quickly rose through the Tampa Bay organization. In 2000, he was ranked the Tampa Bay Devil Rays' ninth-best prospect. In 2001, he was considered the fifth-best prospect in the organization. By 2002, just two years after being drafted sixth overall, he won the Baseball America Minor League Player of the Year Award.Minor League Baseball History Baseball-Reference.com
Tampa Bay Devil Rays/Tampa Bay Rays 2003–04: Early success Baldelli made his major league debut on Opening Day , starting in center field. He and fellow rookie outfielder Carl Crawford would be two of the few bright spots on a Devil Rays team that lost 91 games. Baldelli finished the 2003 season batting .289 with 11 home runs, 78 RBI, 89 runs scored and 27 stolen bases. He also finished in the top ten in many hitting categories in the American League. He was seventh in at bats with 637, tenth in hits 184, tied Ichiro Suzuki in eighth place with eight triples, and fourth in singles with 133.USA TODAY. Baseball-Reference.com. n.d. Electronic. November 20, 2013. He also led the AL in outfield assists and ranked 2nd in range factor, indicating that he was one of the best defensive outfielders in baseball. Baldelli came in third in the voting for 2003 AL Rookie of the Year behind New York Yankees' outfielder Hideki Matsui and winner Ángel Berroa of the Kansas City Royals.
Baldelli had a similar sophomore campaign in , batting .280 with 16 home runs, 74 runs batted in, 79 runs scored and 17 stolen bases. His defensive statistics were again among the league's best, as he led the AL in range factor and finished 4th in outfield assists.Rocco Baldelli Statistics and History Baseball-Reference.com
2005–06: Injuries and renewed success Baldelli started the season on the disabled list after tearing his anterior cruciate ligament over the offseason while playing baseball with his brother. He had surgery and was expected to be back by the All-Star break. However, he seriously injured his elbow while working out and needed Tommy John surgery to fix the damage, which led to months more rehabilitation.
After missing almost a full season and a half, Baldelli returned to the D-Rays' lineup against the Los Angeles Angels of Anaheim on June 7, 2006. Baldelli was a regular starter in the outfield for the rest of the 2006 campaign and had his best statistical season, hitting .302 with 16 home runs, 57 runs batted in, 57 runs scored and 10 stolen bases in only 364 at bats and again appearing among the league leaders in multiple defensive categories.
2007–08: Medical issues In spring training before the 2007 season, Baldelli pulled his hamstring. The injury lingered, but Baldelli attempted to play, appearing in 35 games (15 as a designated hitter) and posting only a .204 batting average. He aggravated his hamstring in May and was placed on the DL on May 17. Doctors recommended a period of rest, after which Baldelli reported to the minor leagues for a rehab assignment. After several games, he injured his hamstring yet again and was shut down for the remainder of the 2007 season.
After these setbacks, Baldelli underwent extensive medical testing to determine the reasons for his muscle problems and worsening fatigue after even brief workouts. Doctors discovered some "metabolic and/or mitochondrial abnormalities" and began trying to design a medical plan to improve the condition.
Baldelli attempted to return to game action during spring training in 2008, but his continuing physical problems made it impossible. On March 12, he held an emotional press conference in which he announced that he would be once again placed on the disabled list as he tried to find an effective treatment for his mysterious ailment. Though he did not retire, the future of his baseball career was in doubt. Accordingly, on April 1, 2008, the Rays declined Baldelli's contract option for the following season (2009), potentially making him a free agent after the season.
After further medical consultations, Baldelli's doctors found a combination of medications and nutritional supplements that seemed to improve his condition. On May 29, 2008, he began playing in extended spring training games, and in mid-June was sent to play in the Rays' minor league system for further rehabilitation and conditioning in the hope that he might return to the majors during the 2008 season.
Return to the field On August 10, 2008, Baldelli was activated and started in right field for the Rays in a game against the Seattle Mariners. Baldelli had been growing a beard for months as a "symbol of his rehabilitation" and shaved it off before playing. In the contest, he had an RBI single as well as a diving catch before coming out of the game after the 5th inning.
Baldelli ended up appearing in 28 games for the Rays in 2008, mainly as a DH and pinch hitter but occasionally playing in right or left field. He hit .263 with 4 home runs and 13 RBI, and was deemed valuable enough to be included in the Rays' postseason roster as they made the playoffs for the first time.
Baldelli made an impact in his limited post-season playing time. In Game 3 of the 2008 American League Championship Series, Baldelli hit a three-run home run off Boston's Paul Byrd in the eighth inning to help the Rays take a 2-1 series lead. In the decisive Game 7 of the ALCS, his RBI single in the fifth inning gave the Rays their first lead of the game en route to winning their first American League pennant. In Game 2 of the World Series against the Philadelphia Phillies, Baldelli made a double play by catching a fly ball and throwing back to first baseman Carlos Peña in time to beat Jayson Werth. Finally, in Game 5, Baldelli hit a solo home run in the top of the seventh that tied the game for the Rays, although it wouldn't prevent the Rays from losing the game and ultimately the series.
Because of Baldelli's performance in the 2008 ALCS, many become aware about mitochondrial disease and how it affects the many people that have it. One article reported that a child with mitochondrial disease pretends he is Baldelli when he is at bat. During the Red Sox series, the United Mitochondrial Disease Foundation created a page on its website where children and parents could post notes for Baldelli. One such post read "I am a nine year old boy with Mito. I also like to play baseball. Great home run in the playoffs, I am cheering for you at home. How are you feeling?"
Overall, Baldelli hit .200 in 20 postseason at-bats with two home runs and six RBI. While improved, his medical condition prevented him from playing in back-to-back games, and he sometimes sat down to rest on the field during breaks in the action.
After the season, Baldelli was the recipient of the 2008 Tony Conigliaro Award, which is annually presented to a major league player who has "overcome adversity through the attributes of spirit, determination and courage that were trademarks of Tony Conigliaro."
