Jaime Navarro of the Chicago cubs hit 14 times and every at bat was a home run, 1998

Esteban Yan of the Tampa Bay Devil Rays in 2000. He had only one official at-bat that year (he also had a sacrifice bunt) and hit a home run. Perhaps most remarkably, Yan's homer came on the first pitch thrown to him as a professional baseball player - he hadn’t swung a bat in a game of any kind in ten years! He also got the win in that game, which the Devil Rays took 15-5. The unfortunate Mets pitcher that day was Bobby Jones. Boxscore: http://www.retrosheet.org/boxesetc/B06040NYN2000.htm Yan has since had another at-bat, and stroked a single, maintaining his career batting average at 1.000.

Ed Sanicki (1949), Clem Labine (1955) & Keith McDonald (2000), all had 3 hits during the season of which all 3 were home runs. -----Player-------------------YEAR-------HR--------H T1 Ed Sanicki---------------1949--------3--------3 T1 Clem Labine--------------1955--------3--------3 T1 Keith McDonald-----------2000--------3--------3 4 Robert Person------------2002--------2--------2 Here's a list of players that had 1 hit, which was HR in a season: T1 Mark Hendrickson 2003 1 1 T1 Andy Etchebarren 1965 1 1 T1 Turk Farrell 1957 1 1 T1 Curt Flood 1957 1 1 T1 Jim Gentile 1957 1 1 T1 Dwight Gooden 1999 1 1 T1 Jim Gott 1987 1 1 T1 Wayne Granger 1971 1 1 T1 Danny Graves 2000 1 1 T1 Danny Graves 2001 1 1 T1 Zack Greinke 2005 1 1 T1 Bob Grim 1957 1 1 T1 Kelly Gruber 1984 1 1 T1 Brad Gulden 1980 1 1 T1 Craig Lefferts 1986 1 1 T1 Stan Johnson 1960 1 1 T1 Jerry Adair 1960 1 1 T1 Frank Kreutzer 1965 1 1 T1 Walt Kinney 1923 1 1 T1 Ted Kazanski 1955 1 1 T1 Jeff Juden 1995 1 1 T1 Harry Gumbert 1948 1 1 T1 Stan Jok 1955 1 1 T1 Mel Hall 1981 1 1 T1 Jason Johnson 2005 1 1 T1 Chris Jelic 1990 1 1 T1 Fred Hutchinson 1953 1 1 T1 Joe Hoerner 1966 1 1 T1 Ed Hobaugh 1963 1 1 T1 Hugh East 1942 1 1 T1 Tim Jordan 1910 1 1 T1 Bret Barberie 1996 1 1 T1 Jewel Ens 1925 1 1 T1 Ron Blackburn 1959 1 1 T1 Jeff Bittiger 1986 1 1 T1 Tim Birtsas 1989 1 1 T1 Hal Bevan 1961 1 1 T1 Bob Bowman 1941 1 1 T1 Skeeter Barnes 1987 1 1 T1 Bernardo Brito 1995 1 1 T1 Dan Bankhead 1947 1 1 T1 Doug Bair 1981 1 1 T1 Mark Bailey 1990 1 1 T1 Stan Bahnsen 1979 1 1 T1 Nick Altrock 1918 1 1 T1 Ron Allen 1972 1 1 T1 Gary Bell 1965 1 1 T1 Joe Coleman 1950 1 1 T1 Scott Lusader 1988 1 1 T1 John Dolan 1893 1 1 T1 Don Demeter 1956 1 1 T1 Zach Day 2004 1 1 T1 Jason Davis 2004 1 1 T1 Sam Bowen 1978 1 1 T1 Pete Conway 1889 1 1 T1 Dave Eiland 1992 1 1 T1 Dave Cole 1953 1 1 T1 Doug Clemens 1963 1 1 T1 Doug Clarey 1976 1 1 T1 Dave Campbell 1968 1 1 T1 Dave Burba 1998 1 1 T1 Mike Brumley 1995 1 1 T1 Tripp Cromer 1998 1 1 T1 Luke Stuart 1921 1 1 T1 Roxey Roach 1912 1 1 T1 Roberto Rodriguez 1970 1 1 T1 Eddie Rogers 2005 1 1 T1 Jim Rooker 1980 1 1 T1 Chuck Rose 1909 1 1 T1 Bob Roselli 1956 1 1 T1 Nelson Santovenia 1992 1 1 T1 Hank Sauer 1959 1 1 T1 Ray Scarborough 1953 1 1 T1 Calvin Schiraldi 1989 1 1 T1 Lou Sleater 1958 1 1 T1 Lee Smith 1982 1 1 T1 Alfonso Soriano 1999 1 1 T1 Bill LeFebvre 1938 1 1 T1 John Vukovich 1976 1 1 T1 Mitch Williams 1989 1 1 T1 Jerry Willard 1994 1 1 T1 Rob Wilfong 1987 1 1 T1 Derrick White 1998 1 1 T1 John Wetteland 1990 1 1 T1 Tim Stoddard 1986 1 1 T1 Lou Stringer 1948 1 1 T1 Bill Virdon 1968 1 1 T1 John Van Benschoten 2004 1 1 T1 Rusty Tillman 1988 1 1 T1 Ted Tappe 1950 1 1 T1 Tom Sullivan 1922 1 1 T1 Jon Rauch 2004 1 1 T1 David West 1995 1 1 T1 Denny McLain 1963 1 1 T1 Craig Reynolds 1976 1 1 T1 Guillermo Mota 1999 1 1 T1 Jerry Moses 1965 1 1 T1 Guy Morrison 1927 1 1 T1 Mike Mordecai 1994 1 1 T1 Gary Neibauer 1973 1 1 T1 Hensley Meulens 1998 1 1 T1 Dick Nen 1963 1 1 T1 Tim McIntosh 1990 1 1 T1 Jason Maxwell 1998 1 1 T1 Carmen Mauro 1948 1 1 T1 Dave Matranga 2003 1 1 T1 Pete Mackanin 1979 1 1 T1 Jose Macias 1999 1 1 T1 Hack Miller 1944 1 1 T1 Esteban Yan 2000 1 1 T1 Bobby Ramos 1982 1 1 T1 Jamie Quirk 1984 1 1 T1 Curtis Pride 2003 1 1 T1 Bob Priddy 1968 1 1 T1 Buster Narum 1963 1 1 T1 Jim Pisoni 1953 1 1 T1 Jessie Reid 1987 1 1 T1 Gary Pettis 1982 1 1 T1 Pat Perry 1988 1 1 T1 Geronimo Pena 1996 1 1 T1 Ike Pearson 1946 1 1 T1 Tom O'Malley 1985 1 1 T1 Gregg Olson 1998 1 1 T1 Bob Porterfield 1958 1 1
