Baltimore Orioles (1975–1987) Breaking into the big leagues (1975–1976) Flanagan was selected again in the
1973 MLB draft, this time by the
Baltimore Orioles in the 7th round (159th overall). When he signed with the Orioles, the ball club agreed to finance the remainder of his college education. His MLB career began with two appearances against the
New York Yankees in the last month of the
1975 campaign. He made his debut pitching
innings in relief of starter
Wayne Garland in a 5–4 victory in the opener of a
twi-night doubleheader at
Memorial Stadium on September 5. His first start and
decision was a 3–2 loss at
Shea Stadium in the nightcap of another twin bill 23 days later on September 28 which was the final game of the regular season. He was on the verge of a
shutout until the bottom of the ninth when the first three batters he faced reached base and
Dyar Miller allowed all of them to score on a
single and an
error. Flanagan's 1976 campaign was split between Rochester and Baltimore. He did not get his first Major League win until a 7–1
complete-game triumph at home over the eventual
American League (AL) West champion
Kansas City Royals on September 1. In 20 games (10
starts), he had a 3–5 record, a 4.13 ERA, 56 strikeouts, 33
walks, and 83
hits allowed in 85 innings pitched. In 1978, Flanagan was the Orioles'
Opening Day starter, the only year from 1974 through 1980 that
Jim Palmer did not make the Opening Day start for Baltimore. Flanagan had a 10–1 record from May 5 through June 22, 1978, including a six-game winning streak from May 31 through June 22. He was selected to his only
All-Star Game in 1978 after posting a 12–6 record and a 3.16 earned run average before the All-Star Break. Three times he pitch over nine innings in a game: 11 on June 13 in a 3–2 victory over the
Seattle Mariners, 11 on July 17 in a 2–0 loss to the
Texas Rangers, and on September 22 in a 7–5 loss to the Tigers. Flanagan was a workhorse for the Orioles in 1978, tying with
Dennis Leonard for the AL lead with 40 games started and ranking fourth in the AL with innings pitched (behind teammate Palmer's 296, Leonard's , and
Mike Caldwell's ), though he also led the AL in
earned runs allowed with 126. His 19 wins were tied with
Paul Splittorff for seventh in the AL, and he also tied with four others for fifth in the AL with 15 losses. He had a 4.03 earned run average and ranked fourth in the AL with 167 strikeouts (behind
Nolan Ryan's 260,
Ron Guidry's 248, and Leonard's 183).
Cy Young Award winner (1979) After posting a 12–6 record and a 4.05 earned run average before the All-Star break in 1979, Flanagan posted a 12–3 record and a 2.15 earned run average in the latter part of the season. From July 9 through September 13, the Orioles only lost one game he pitched, an outing against the Yankees where Flanagan allowed three runs in a complete game but
Tommy John allowed only two for New York. Flanagan posted a 12–1 record over 15 games during the stretch. In the second game of a doubleheader against the
Toronto Blue Jays on September 1, Flanagan allowed one run and seven hits in a complete game, 5–1 victory, becoming the first pitcher in the major leagues to win 20 games in 1979. He won the
Cy Young Award and the
Sporting News AL Pitcher of the Year Award, also finishing sixth in
AL Most Valuable Player (MVP) voting as the Orioles won the
AL East. The starter for Game 2, Flanagan held the Angels to three runs through seven innings before getting pulled in the top of the eighth after the first three runners reached (though
Rod Carew did so on an
error). He was charged with six runs (four earned) in seven innings but picked up the win in Baltimore's 9–8 victory; Baltimore defeated the Angels in four games. Flanagan started Game 1 of the
World Series, allowing four runs to the
Pittsburgh Pirates but pitching the whole game in Baltimore's 5–4 triumph. Flanagan also was one of five pitchers the Orioles used in the ninth inning of Game 7. He gave up a single to the only batter he faced,
Omar Moreno, who later scored as Pittsburgh went on to win the game 4–1 and the series 4–3. After Flanagan's season ended, on November 10, his hometown of Manchester honored him with "Mike Flanagan Day", in which he was escorted through town in a
motorcade to the applause of over 1,000 spectators. Although his earned run average was more than one run higher for the team in 1980, he had a winning record once again. The
1981 Major League Baseball strike resulted in the cancellation of games in June and July. Flanagan's season was further interrupted in September, when
tendonitis ended his streak of 157 scheduled starts made. "It's just an oil change and a 30,000-inning checkup," he told reporters. With no interruptions to his season this time, he was again able to pitch over 200 innings, with 236 thrown. However, he suffered a major injury in the first inning of the opener of a doubleheader against the
Chicago White Sox on May 17, twisting his left knee. The injury kept him out of action until August 7 and kept his knee in a brace until May 24, 1984. Still, Flanagan won five games in a row from August 28 through September 17 as Baltimore won the AL East title. In Game 3 of the
ALCS against the White Sox, Flanagan held the team to one run before getting replaced by
Sammy Stewart in the sixth inning with his team up 6–1. He was awarded the victory in the 11–1 triumph, and Baltimore went on to defeat Chicago in four games. He started Game 3 of the
World Series against the
Philadelphia Phillies, giving up solo home runs to
Gary Matthews and
Joe Morgan before getting pinch-hit for by
Ken Singleton in the fifth inning, as Baltimore had a man on second with two outs and a chance to score its first run against
Steve Carlton. Singleton struck out, but the Orioles went on to win 3–2 before eventually winning the series in five games. Though 1979 was his best season statistically, Flanagan considered the World Championship campaign of 1983 as his best year in baseball. In 34 games (all starts), he had a 3.53 ERA, 115 strikeouts, 81 walks, and 213 hits allowed in innings. It was the last season in which he would record at least 100 strikeouts. In 15 starts, he had a 4–5 record, a 5.13 ERA, 42 strikeouts, 28 walks, and 101 hits allowed in 86 innings pitched. In 29 games (28 starts) in 1986, he had a 7–11 record, a 4.24 ERA, 96 strikeouts, 66 walks, and 179 hits allowed in 172 innings pitched. When Flanagan joined the Blue Jays, the team released
Phil Niekro to make room for him on their roster. His most memorable performance with the Blue Jays took place at
Tiger Stadium on October 3, 1987, the penultimate game of the regular season. With Toronto in a first-place tie with Detroit and having lost its last five contests, Flanagan outlasted
Jack Morris by pitching 11 innings before departing with the match deadlocked at 2–2. The Blue Jays ended up losing the game 3–2 one inning later and the
AL East championship the following afternoon. Morris said after the game, "Flanagan was so great, so competitive, that I considered my job to be survival – somehow keep us tied until he left the game. We weren't going to get to the playoffs beating him, we could only get there surviving him." Healthy all season, he pitched 211 innings, topping the 200-inning mark for the first time since 1984 and last time in his career. In 30 games (all starts), he had an 8–10 record, a 3.93 ERA, 47 strikeouts, 47 walks, and 186 hits allowed in innings. He took the loss in the game, and the Athletics went on to win the series in five games. Flanagan's final appearance with Toronto was a start that resulted in a 3–1 loss at home to the Tigers on May 4, 1990, as he surrendered all 3 runs in innings. He was released on May 8. In five starts, he had posted a 2–2 record, a 5.31 ERA, five strikeouts, eight walks, and 28 hits allowed in innings pitched. On September 27, manager
Johnny Oates brought him in to record the last two outs by an Oriole pitcher in the final baseball game played at Memorial Stadium, a 7–1 loss to the Tigers. In 64 games (just one of which was a start), he had a 2–7 record, a 2.38 ERA, 55 strikeouts, 25 walks, and 84 hits allowed in innings. He also recorded three
saves, giving him a total of four in his career, as he had previously recorded one in 1977. In 42 games, all in relief, he had no record, an 8.05 ERA, 17 strikeouts, 23 walks, and 50 hits allowed in innings. ==Legacy==
