though he started four games for Calgary as well. Sixteen of his 41 appearances for Seattle were multiple-inning efforts, such as a game on May 11, when he pitched five scoreless innings of relief in a 4–3 loss to the Toronto Blue Jays. He started the second game of a doubleheader on June 7 and made three starts from June 28 through July 8, allowing two runs in innings in an 8–5 victory over the Kansas City Royals on July 1, though Guetterman did not get the decision. In 41 games, he had an 0–4 record, 38 strikeouts, 30 walks, and 108 hits allowed in 76 innings pitched. His 7.34 ERA was the highest among American League (AL) pitchers with at least 75 innings pitched. Not even invited to 1987 spring training, Guetterman began the season in the bullpen at Calgary, posting a 5–1 record and a 2.86 ERA in 16 appearances (two starts). Promoted by the Mariners in late May when another starter went on the disabled list, he entered a tie game against the New York Yankees in the beginning of the sixth inning on May 27, throwing two scoreless innings as the Mariners took the lead. He was removed in the eighth after walking Don Mattingly to lead off the inning, and Jerry Reed eventually allowed Mattingly to score, but the Mariners held on to win 6–5, and Guetterman was credited with the victory, his first ever in the major leagues. He then joined the starting rotation, winning his next four decisions for Seattle. In one of those, on June 26 against the Cleveland Indians, he allowed just three hits in his only major league shutout. After a loss, he won three more decisions in a row and had an 8–1 record by the All-Star break. He had a 6.29 ERA in his next six starts, losing three of four decisions, before getting moved to the bullpen. "Lee won five in a row and then lost his command,” said Billy Connors, the Mariners' pitching coach. “He seemed afraid to let the guys hit the ball. That’s trouble for a sinkerball pitcher." As a reliever, Guetterman posted a 1.69 ERA in seven outings. He made two more starts at the end of the season, winning both of them. In 25 games (17 starts), he had an 11–4 record, a 3.81 ERA, 42 strikeouts, 35 walks, and 117 hits
