The Blue Jays traded McGuire to the White Sox before the 2022 season, and the White Sox traded him to the Red Sox during the 2022 season.
McGuire was one of several highly regarded prospects to join the Low-AWest Virginia Power for the 2014 season.[13] As a South Atlantic League prospect, McGuire demonstrated at 1.8-second pop time behind the plate, as well as consistent contact hitting.[14] Batting .277 with one home run and 19 RBI through the midway point of the season, including a 19-game hitting streak in May, McGuire was named a South Atlantic League All-Star.[15] He finished the season batting .262 with three home runs and 45 RBI in 98 games.[12] After the season, McGuire added 15 pounds of muscle and told reporters that he wanted to "come up with a consistent approach at the plate and stick with it" in 2015.[16]
McGuire opened the 2015 season with the Class A-AdvancedBradenton Marauders of the Florida State League (FSL).[17] After hitting .259 to start the season, with 10 stolen bases and throwing out 14 opposing base stealers, McGuire was named an FSL All-Star in June.[18] He finished the season batting .254 with 15 doubles and 34 RBI.[12] While McGuire's defensive ability received praise from coaches, his offense was not as well-developed by the end of the season. After two consecutive seasons seeing his batting average decrease, McGuire joined the Glendale Desert Dogs of the Arizona Fall League to improve his offense. In 14 games there, he hit .294 with five extra-base hits.[19][20]
McGuire was one of 12 Pirates prospects invited to attend spring training with the team in 2016.[21] After being reassigned to minor league camp in March,[22] he opened the season with the Double-AAltoona Curve.[23] One of the youngest players on the team, McGuire showed more consistency and discipline at the plate, drawing walks and keeping his batting average above .250, although he still lacked power.[24] In 266 at bats across 77 games, he hit .259 with one home run and 37 RBI.[12]
McGuire returned to the Fisher Cats for the 2017 season, but was limited to only 45 games after suffering a torn meniscus in his right knee that required arthroscopic surgery to repair.[26] After suffering the knee injury in early May, McGuire was able to return to Double-A at the start of August,[27] and shortly after his return, McGuire's home runs in three consecutive games earned him Eastern League Player of the Week honors for the week ending August 20.[28] In his limited appearances in 2017, McGuire batted .295 with six home runs and 28 RBI in 149 at bats.[12]
On November 20, 2017, the Blue Jays added McGuire to their 40-man roster, protecting him from the Rule 5 draft.[29] He played for the Buffalo Bisons of the Triple-AInternational League in 2018.[30] On September 6, 2018, the Blue Jays promoted McGuire to the major leagues.[31] He made his MLB debut that night against the Cleveland Indians and hit a double in the game for his first career hit. He hit his first career home run on September 26 against the Houston Astros.[32] In 14 major-league games, McGuire batted .290 with two home runs and four RBIs.[33]
McGuire did not make the 2019 opening day roster and was optioned to Triple-A.[34] McGuire joined the Blue Jays in late July after Luke Maile was injured, and appeared in 30 games throughout the season, hitting .299 with an .872 OPS.[35] Overall with the 2020 Blue Jays, McGuire batted .073 with one home run and one RBI in 19 games.[36]
On April 1, 2021, McGuire was designated for assignment by the Blue Jays.[37] Clearing waivers, he was assigned to the Jays' alternate training site,[37] before being assigned to Triple-A Buffalo on May 3.[38] On May 5, McGuire was selected to Toronto's active roster.[39] With Toronto in 2021, McGuire played in 78 games, batting .253 with one home run and 10 RBIs.[33]

On January 13, 2023, the Red Sox and McGuire reached agreement on a one-year contract, avoiding salary arbitration.[43] He served as Boston's backup catcher until June 22, when he was placed on the injured list with a right oblique strain.[44] McGuire was activated on August 1, [45] and hit his first home run of the season later that day.[46] In 72 total appearances, he slashed .267/.310/.358 with one home run and 16 RBI.
On January 12, 2024, McGuire once again avoided salary arbitration with the Red Sox by signing a one-year contract with the team.[47] On April 7, McGuire drove in a career high of five RBI in a 12–2 victory over the Los Angeles Angels.[48] On July 24 against the Colorado Rockies, a benches-clearing brawl occurred after Rockies pitcher Cal Quantrill yelled at McGuire, "you jacked off in a fucking parking lot, you dumb fuck", a reference to McGuire's 2020 arrest for indecent exposure.[49]
On July 28, McGuire was designated for assignment by the Red Sox.[50] In 52 games for Boston, he batted .209/.280/.295 with three home runs and 18 RBI. Red Sox manager Alex Cora explained that the team made a change at the backup catcher position in consideration of roster balance, changing from a left-handed batter (McGuire) to a right-handed batter (Danny Jansen).[51] McGuire cleared waivers and was sent outright to the Triple–A Worcester Red Sox on August 2.[52] He elected free agency on September 30.[53]
