June, yet Casey Stengel chose Garver to start the All-Star Game in early July, which Garver later called "one of the biggest thrills I've ever experienced." He allowed one unearned run in three innings, receiving a no decision in an 8–3 defeat. Against the Philadelphia Athletics on August 24, Garver was the pitcher for the Browns on "Grandstand Managers Night," a promotion in which the fans held up large placards with "Yes" or "No" printed on them and made decisions on the team's strategy in the game against the Athletics. Garver recalled at one point during the game, the Athletics had runners on first and third base with only one out. He wanted the team to play the infielders farther to the plate, which would make a double play more likely. The fans, however, voted twice to play the infield in. Realizing this was not a good strategy, catcher Sherm Lollar called time and headed out to the mound to talk to Garver, then started walking around behind home plate when he returned to his position, to delay the game. Prompted a third time by the coach as to whether to play the infield in or not, the fans finally changed their vote to "No." Garver got Pete Suder to hit into a double play to end the inning, and he pitched a complete game as the Browns won 5–3. Facing the White Sox in the season's final game on September 30, Garver needed a victory to attain the 20-win milestone. With the score tied at four in the fourth inning, Garver hit his only home run of the season, against Randy Gumpert, to put his team ahead. With Garver not pitching well in the early innings, Lollar suggested that the pitcher rely on his sinking fastball exclusively for a few innings, then return to throwing all his pitches later in the game. After allowing four runs through the first four innings, Garver allowed just one unearned run the rest of the game. The Browns won 9–5, and Garver won his 20th. The Commissioner of Baseball sent him a plaque to commemorate the victory. In 1951, Garver compiled a 20–12 record with a 3.73 ERA, 84 strikeouts, 96 walks, and 237 hits allowed in 246 innings. Offensively, he compiled .305 batting average with one home run and nine RBI. He was also used as a pinch hitter and pinch runner.
