Mike Marshall: 1968-69 Mayagüez Indios to Record-Setting AL and NL Reliever (Part I)

It is rare for a Cy Young Award winner to earn a Ph.D. in exercise physiology while still an active big leaguer. Mike Marshall did just that, becoming the first reliever in big league history to win the Cy Young—with the 1974 Los Angeles Dodgers—four years before obtaining his 1978 Ph.D. from Michigan State University, where he secured his bachelor’s and master’s degrees. Per his SABR bio by Warren Corbett, Marshall worked out with weights and ran long distances instead of sprints; believed in pitching more, not less; threw a screwball; refused to sign autographs for the majority of his career since he didn’t think ballplayers should be heroes; and, his pickoff move turned the wrong way. https://sabr.org/bioproj/person/mike-marshall/ Marshall was the shortest Cy Young recipient at 5-8 and one-half inches, the same height as the shortest 20th century U.S. President, Harry S Truman. Part I will focus on Marshall’s career through the 1969 Seattle Pilots. Part II covers his 1970-1976 timeframe with Houston, Montreal, and the Dodgers. Part III concludes with Atlanta, Texas Rangers, Minnesota Twins, and New York Mets, 1976-1981.

Detroit Tigers and their Connection to Mayagüez Indios, 1958-59 to 1978-79

Marshall was born in Adrian, Michigan, on January 15, 1943. In his senior year at Michigan State (1964-65), Mayagüez formalized a working agreement with the Detroit Tigers that continued into the 1970s. The 1964-65 Indios, managed by Bob Swift, featured a pitching staff with Dennis McLain, Joe Sparma, and Bob Dustal, among others. Willie Horton, Jim Northrup, and Mickey Stanley were a trio of young Tigers who plied their trade with Mayagüez. The Indios reached the Puerto Rico Winter League (PRWL) finals before losing to Santurce. The 1965-66 Indios did win the PRWL crown, topping Ponce in the finals. Wayne Blackburn managed them; Northrup won the batting title; Detroit prospect Billy Graham won 12 games; and lefty John Hiller pitched well. Northrup and Stanley returned; Ray Oyler played shortstop, and Fritz Fisher contributed to the mound. Between 1958-59 and 1963-64, a handful of Tigers reinforced Mayagüez, ranging from pitchers Bob Bruce, Pete Burnside, and Jerry Davie in 1958-59 to Phil Regan (1960-61), to Gates Brown and Fred Gladding in 1963-64. Jorge Colón Delgado’s superb 2019 book, documenting the history of the Mayagüez Indios, and Héctor Matías Marrero’s 2023 book with Mayagüez team rosters and stats are must-reads on this franchise, 1938-39 to present. The Detroit-Mayagüez connection ended after the 1978-79 season when Jack Morris and Sheldon Burnside pitched to Lance Parrish with the Indios.

Parrish recalled: «To be able to play with Jack down there just kind of furthered our growth as pitcher and catcher in the Detroit organization. I caught him a couple of seasons in the minors, then had the opportunity to catch Jack in the PRWL, and then worked with him in the majors. It was another step in our progression as major leaguers.»

Marshall, a Cy Young Winner 50 Years Ago

Table I includes all Cy Young winners who pitched in the PRWL, beginning with Bob Turley (1958 Yankees) and concluding with David Cone (1994 Royals). Ten AL recipients and eight NL recipients had PRWL experience. Dwight Gooden pitched for San Juan a decade after winning his 1985 Cy Young. Mike Cuéllar continued pitching in the PRWL after sharing the 1969 Cy Young Award with Detroit’s McLain. Just three big league relievers who pitched in the PRWL—Mike Marshall (1974 Dodgers), Willie Hernández (1984 Tigers), and Mark Davis (1989 Padres)—won the Cy Young. Marshall was a starter for 1968-69 Mayagüez; Hernández started and mostly relieved for PRWL teams; Davis only relieved for 1992-93 San Juan, trying to resurrect his career after his 1989 Cy Young NL season. Turley recalled that the New York Yankees scouted him in the PRWL before a 17-player trade between Baltimore and the Yankees a year later, sending Turley to the Bronx Bombers. «Puerto Rico was crucial for my career,» stated Turley. «I took the bus from my San Juan apartment to Sixto Escobar Stadium and later [1962-63] pitched one game for San Juan at the new stadium [Hiram Bithorn] before returning home.»

Marshall in the Minors, 1967 Detroit, and 1968-69 Mayagüez

Philadelphia signed Marshall as an amateur free agent on September 13, 1960, but he did not pitch in their minor league system until 1965. The Phillies sold him to Detroit on April 11, 1966. Marshall went 11-7 in 51 relief appearances for the 1966 Montgomery (Alabama) Rebels, managed by Wayne Blackburn, long-time Indios manager, along with Cal Ermer. Marshall’s 2.33 ERA and 1.27 WHIP were in 108 innings. Daryl Patterson and Tom Timmermann mostly started for Montgomery and were part of a deep minor-league pitching pool in Detroit’s system. «I was taking off-season college courses at Southern Illinois-University/Carbondale,» recalled Timmermann, who was 26. Timmerman finally made it to the majors in 1969, at age 29, following several fine winter seasons for the Caguas Criollos. Patterson surfaced on Detroit’s 1968 World Series championship ballclub and could start or relieve. «The competition for a spot with Detroit was intense, then,» recalled Patterson. «I later [1971-72] pitched for a PRWL championship team—Ponce Lions.» Twenty-eight-year-old third baseman Eddie Olivares, Brooklyn-born of Puerto Rican parents, played for Montgomery.

Marshall was promoted to Detroit in 1967 and was retroactively credited with ten saves in 37 games. He was 1-3 with a 1.98 ERA and 1.20 WHIP, recording 41 strikeouts to 20 outs. Yet Detroit demoted him to the 1968 Toledo Mud Hens (83-64), winners of the regular season title by a half-game over the Columbus Jets (82-64). Marshall, primarily a starter, made the 1968 International League (Triple-A) All-Star Team, going 15-9, with a 2.94 ERA and 1.15 WHIP. He started 28 of 31 games. In 211 innings, he fanned 190 and walked 52. Dick, «The Monster Radatz,» began and relieved for Toledo, who also featured Dick Drago (15-8) and Jim Rooker (14-8) in the rotation. Twenty-year-old prospect Les Cain went 7-5 in 13 starts, while Timmerman’s 35 games included seven starts.

Detroit sent Marshall to Mayagüez as a starter for skipper Wayne Blackburn. Marshall went 6-6, with a 3.06 ERA for the fifth-place Indios, with a 2.4 strikeout-to-walk ratio (63-26), in 103.1 innings. Blackburn opined that Marshall had a «solid work ethic,» albeit «his routine was completely different than other PRWL hurlers.» Ike Brown, Les Cain, and Ozzie Virgil Sr. were three of Marshall’s teammates. Brown was the last Negro Leaguer to play in the PRWL when he suited up for Mayagüez in 1968-69 and 1969-70. Santurce, led by 33-year-old rookie skipper Frank Robinson, won a franchise-best 49 games, per Table II. Sparky Anderson managed San Juan to a fourth-place finish, followed by an upset win over arch-rival Santurce in the best-of-seven semi-finals. «Santurce was loaded,» said Anderson. «They had the best club, with George Scott, Julio Gotay, Leo Cárdenas, Joe Foy, Elrod Hendricks, Paul Blair, Jim Palmer, Juan Pizarro, and Rubén Gómez…» Palmer (5-0, 2.79 ERA) was Santurce’s fourth starter, having missed half of the season due to shoulder issues, behind Pizarro (8-5, 1.93), Gómez (9-1, 2.05), and Wally Bunker (8-4. 2.06). Other league managers were: Rocky Bridges (Ponce), Luis «Tite» Arroyo (Caguas), and Vic Power (Arecibo).

1969 Toledo Mud Hens and Seattle Pilots

On October 15, 1968, Marshall was selected by the Seattle Pilots (53rd overall pick) from Detroit in the expansion draft. He started 11 games for the 1969 Toledo Mud Hens before Seattle promoted him. Coincidentally, Tom Timmermann also started 11 times for Toledo before his call-up by Detroit in mid-June 1969. Table III compares Marshall’s Mud Hens pitching stats to those of Timmermann. Marshall went 3-10 with a 5.13 ERA with Seattle, starting 14 games and relieving six times. He pitched three CG and one SHO in 87.2 innings. Sal Maglie, Seattle’s pitching coach, discouraged Marshall from throwing the screwball, his (Marshall’s) favorite pitch. (Mayo Smith, Detroit’s skipper, also told Marshall to discontinue throwing the screwball in 1967.) Jim Bouton—a 1969 Pilots teammate of Marshall—became well known after writing Ball Four, a baseball classic.

Post Script

When Caguas radio broadcaster Héctor Rafael Vázquez told listeners, in 1967-68: «Warming up in the bullpen, Tom Timmermann,» it sent chills up the spines of opponents’ fans, such as the author, who avidly followed Santurce.

Thanks to Sparky Anderson, Wayne Blackburn, Lance Parrish, Darryl Patterson, Tom Timmermann, and Bob Turley. Jorge Colón Delgado, who furnished Marshall’s PRWL 1968-69 pitching stats, did the editing and photo placements.
