Tomlin won his first four starts of the 1992 season; "Sports Illustrated" wrote in May that he and the other Pittsburgh starting pitchers "are racking up W's like unlucky Scrabble competitors." After losing three decisions in a row, he then won his next six decisions, including five starts in a row from June 2 through June 22. During the streak, he threw 26 consecutive scoreless innings, which included a complete game shutout of the Mets on June 7. He was named the NL Player of the Month for June. Through the 22nd of the month, he was tied with four others for most wins in the major leagues. His ERA was 3.03 at that point, and it would be 3.69 for the rest of the year, but Tomlin would win just four more games. He pitched back-to-back one-run, eight-inning games against the St. Louis Cardinals on August 2 and 7, earning the win in the second of those (the Pirates won both). In 33 starts, he had a 14–9 record, a 3.41 ERA, 90 strikeouts, and 42 walks in innings pitched. Tomlin finished 10th in the NL with a .609 winning percentage and fifth in the NL in walks per nine innings pitched, though he was also third with 226 hits allowed (behind Andy Benes's 230 and Terry Mulholland's 227). NL East Champions again, the Pirates faced the Braves in the NLCS for the second year in a row. In Game 2, he pitched scoreless innings of relief, though the Pirates were already losing 8–0 and would lose 13–5. He relieved Doug Drabek in Game 4 with the game tied at three, runners on first and third, and one out in the fifth inning. After an error allowed a run to score, Tomlin induced Ron Gant to hit into an inning-ending double play, but Tomlin would allow two runs in the next inning as Pittsburgh went on to lose 6–4. The Pirates lost the series in seven games.
