He returned to the minors for the 1975 season, batting .285 with 44 stolen bases for the Tulsa Oilers. He was called up again that September, and got his first major league hit in his first at bat. He also scored Héctor Cruz on the play for his first major league RBI.[3] Overall, he went 6-for-16 with the one RBI and two runs scored.
St. Louis Cardinals
He was batting .338 in nineteen games for Tulsa in 1976 when he was brought up to fill in for center fielderBake McBride, who was having knee trouble.[4] After going 0-for his first-11, Mumphrey put together a modest eight game hitting streak. Playing the San Francisco Giants on July 6, Mumphrey went 4-for-5 with three runs and an RBI.[5] The next day, Giants pitcherJohn Montefusco faked a throw to third, and spun around to pick Mumphrey off first base. Instead of being tagged out, Mumphrey got in a rundown, allowing Mike Tyson to score from third. Mumphrey was also safe at second.[6] On September 17, he hit his first major league home run and only home run of the season off the Montreal Expos' Gerry Hannahs.[7] His rookie year, he batted .258 with 26 RBIs and 51 runs scored. His 22 stolen bases were second to Cardinals legend Lou Brock's 56.
Mumphrey was only batting .170 at the time of the acquisition. Upon Hendrick's arrival, Mumphrey began hitting. He batted .290 over the remainder of the season to end the 1978 season with a .262 average. On August 5, he went 3-for-4 with his first home run of the season against the Mets.[9] His second home run of the season beat the Houston Astros on August 30.[10]
A Spring training injury kept Mumphrey out of the line up until game eleven of the 1979 season. He had just one hit in his first fourteen at bats before a 3-for-4 performance against the Atlanta Braves on May 12.[11] In an August 10 doubleheader with the Cubs, Mumphrey went 5-for-9 with four RBIs and an inside-the-park home run.[12]
As the Cards' fourth outfielder, Mumphrey appeared in 124 games, and made 375 plate appearances in 1979. Believing that he deserved more playing time, Mumphrey requested a trade. On December 7, he and John Denny were traded to the Cleveland Indians for Bobby Bonds.[13] Two months later, the Indians sent him to the San Diego Padres for Bob Owchinko and Jim Wilhelm.[14]
San Diego Padres
A pulled muscle in his right leg toward the end of Spring training caused Mumphrey to get off to a slow start in 1980,[15] however, by the beginning of June, Mumphrey was batting third, and having a career year. He was second to Gene Richards (.301) with a .298 batting average, and along with Richards and Ozzie Smith, he was part of the first trio from the same team in MLB history to each steal fifty or more bases in a season.
Batting second and playing center, Mumphrey batted .322 and matched his career high home run total (4) in the first half of the strike shortened season.[18] When play resumed, Mumphrey batted .290 with nineteen RBIs and 24 runs scored.
The Yankees won the first half of the split season format instituted for the 1981 season. After going 2-for-5 with a run scored in game one of the 1981 American League Division Series with the Milwaukee Brewers,[19] Mumphrey went hitless in the remaining four games.[20] He reached on an error & scored the Yankees' only run in game six.[21]
Mumphrey singled and came around to score on Bob Watson's home run in his first at bat of the 1981 World Series against the Los Angeles Dodgers. In his next at bat, he singled, stole second, then scored the Yankees' fourth run of the game.[23] An 0-for-8 "slump" that followed got him benched for games four and five, both won by the Dodgers.[24] He returned for game six, got a single in the third, but struck out in the final inning of the Dodgers' World Series victory.[25] Overall, Mumphrey went 11-for-48 for a .229 average in his only trip to the post season. He scored six runs with no RBIs.
Despite the fact that the Yankees fell to 79-83 and fifth place in the American League East in 1982, Mumphrey had a career year where he set several career highs. Facing the A's July 15–18, Mumphrey went 6-for-15 with five RBIs and four runs in the four-game sweep. The Yankees swept the California Angels later in the month. Mumphrey went 6-for-14 with two home runs.[26] On September 29 against the Indians, Mumphrey went 3-for-5 with two doubles, a triple, four RBIs and three runs scored.[27] All told, he batted over .300 for the second year in a row with a career high nine home runs and 76 runs scored. His 68 RBIs were second on the team to Dave Winfield's 106.
The Yankees signed free agent outfielder Steve Kemp before the 1983 season. Wanting more power in his line up, manager Billy Martin began using Kemp in left and Winfield in center when the Yankees faced left handed pitchers. Mumphrey was displeased with the amount of time he was playing with New York. On August 10, he was traded even up to the Astros for Omar Moreno.[28]
Houston Astros
Starting in center field again, Mumphrey ignited one of the Astros' greatest comebacks of the season shortly after joining his new club. On August 23, with the Astros trailing the Pirates 5–1, Mumphrey led off the ninth inning with a single off starterJohn Candelaria. Following Alan Ashby's single, Denny Walling hit a three-run home run to chase Candelaria from the game. The Astros then scored two more off the Pirates' bullpen to win, 6–5.[29] The next day, Mumphrey went 3-for-4 with two doubles, two RBIs and a run scored in the Astros' 10–4 victory over the Pirates.[30] On September 27, Mumphrey went 4-for-5, and broke a 5–5 tie with a three-run home run against the Padres.[31] Mumphrey batted .336 over the rest of the season with Houston.
On May 14, 1984, Mumphrey singled in the bottom of the ninth off Pirates closerKent Tekulve for his one thousandth major league hit. Going into the All-Star break, he batted .282 with six home runs and 52 RBIs to be selected by Paul Owens' as the Astros' sole representative on the National LeagueAll-Star squad. He was struck out by the Detroit Tigers' Jack Morris to end the fourth inning in his only at bat.[32] He batted .301 after the break to bring his average to .290 for the season. He matched his career high with nine home runs (tied with Terry Puhl for 2nd most on the team to José Cruz's 12) and set a new career high with 83 RBIs (2nd to Cruz's 95).
The Cubs' intention to use Mumphrey as a fourth outfielder was made clear immediately. Shortly after his December 1985 acquisition, Cubs General ManagerDallas Green said, "By acquiring Jerry Mumphrey, we got someone who can play three outfield positions and play all three very well."[33]
As a fourth outfielder, he played 111 games and batted .304 in 1986 He was also 10-for-29 as a pinch hitter with one home run and eight RBIs.
He batted a career high .333 in 1987, and set a new career high with thirteen home runs. He was 12-for-35 with two home runs and twelve RBIs as a pinch hitter. In 1988, Mumphrey made 57 plate appearances as a pinch hitter, and only appeared on the field four times. He had nine hits in 66 at bats for a .136 average. He retired at the end of the season.
