From my Twitter feed on Tuesday:
@dschoenfield Hey, David: Who's the best player since 1933 who never made an All-Star game?
— Larry Fahey (@hotdogdynamite) April 22, 2014
This is pretty easy to check. Thanks to Baseball-Reference.com's Play Index, we can search for most career Wins Above Replacement for players who never played in an All-Star Game. By position, we get:
C -- Rick Dempsey (25.3)
1B -- Earl Torgeson (32.7)
2B -- Mark Ellis (33.3)
3B -- Eric Chavez (37.1)
SS -- John Valentin (32.5)
OF -- Tim Salmon (40.5)
OF -- Kirk Gibson (38.3)
OF -- Garry Maddox (36.6)
UT -- Tony Phillips (50.8)
Also in the top 10: Ken McMullen (34.1), Dwayne Murphy (33.2) and Richie Hebner (32.9).
Phillips tops the list with 50.8 career WAR, higher than many Hall of Famers. He was an underrated player who played all over, mostly at second base and the outfield, but he was a shortstop early in his career and started 336 games at third base. During his peak from 1990 to 1997 he averaged .277/.396/.409 and 104 runs per season, more or less playing as a regular for the Tigers, Angels and White Sox while moving around the field. I suspect his utility status hurt him at All-Star time, plus a lot of his value came from drawing walks more than hitting for a high average (he hit .300 once) or for power (hit more than 20 home runs just once).
Gibson told MLB.com in 2011 that he was twice invited as a reserve to the All-Star Game, in 1985 and 1988 (the year he won the NL MVP Award), but turned down the selections. Ellis, Maddox and Murphy were defense-first players, although I was surprised Maddox never made it considering he played for a lot of good Phillies teams. In 1976, he was hitting .321 with five home runs and 40 RBIs at the All-Star break and he'd finish fifth in the MVP vote that year. The National League All-Star outfielders were Greg Luzinski, George Foster and Dave Kingman (starters), plus Bake McBride (.345-3-18 at the break, but St. Louis' only rep), Cesar Cedeno (.297-14-48), Ken Griffey Sr. (.340-4-50) and Al Oliver (.360-12-49 and Pittsburgh's only rep). Pretty tough group to crack.
Salmon's best season came in 1995 when he hit .330 with 34 home runs and 105 RBIs, worth 6.6 WAR (fifth among AL position players that year). The American League All-Star outfielders were Albert Belle, Kenny Lofton and Kirby Puckett (starters), plus Ken Griffey Jr. (injured), Jim Edmonds, Manny Ramirez and Paul O'Neill. Another tough group and Salmon hit .364 in the second half.
You can have a lot of fun doing this. Chavez's best years came from 2000 to 2005 when he averaged .278-30-98 and 4.7 WAR. AL All-Star third basemen those years were Travis Fryman, Troy Glaus, Cal Ripken and Tony Batista (2000); Ripken and Glaus (2001); Shea Hillenbrand, Robin Ventura and Batista (2002); Glaus and Hank Blalock (2003); Alex Rodriguez and Blalock (2004); Rodriguez, Melvin Mora and Hillenbrand (2005). Yes, Shea Hillenbrand started an All-Star Game.
For the pitchers, the top five in career WAR since 1933 to never make an All-Star team:
Tom Candiotti (42.5)
Danny Darwin (40.5)
Charlie Leibrandt (34.4)
Fritz Ostermueller (34.4)
John Tudor (34.3)
The active leader is A.J. Burnett at 27.2.
Tudor didn't make it in 1985, the year he went 21-8 with a 1.93 ERA. He was 10-7 with a 2.27 ERA at the break before going 11-1, 1.59 in the second half (he threw 10 shutouts that year). Not as many pitchers were selected back then so it was more difficult to make it. There were nine NL pitchers and the weakest starter on the staff was the one who actually started, LaMarr Hoyt, who was 12-4 with a 2.93 ERA.
Most career saves to never make an All-Star team? Gene Garber, with 218. Kevin Gregg, with 177, is third on that list and is the active leader.
One more list. Here's the most single-season WAR for players who didn't make the All-Star team that year:
1. John Valentin, 1995: 8.3
2. Josh Donaldson, 2013: 8.0
3. Bernard Gilkey, 1996: 8.0
4. Nick Markakis, 2008: 7.4
5. Brett Gardner, 2010: 7.3
6. Randy Velarde, 1999: 7.0
7. Bill North, 1973: 7.0
8. Andrelton Simmons, 2013: 6.9
9. Dwayne Murphy, 1980: 6.9
10. Chris Hoiles, 1993: 6.8
11. Eddie Lake, 1945: 6.8
12. Solly Hemus, 1952: 6.7
13. Franklin Gutierrez, 2009: 6.6
14. Tim Salmon, 1995: 6.6
15. Rick Wilkins, 1993: 6.6
Valentin actually led AL position players in WAR in 1995, hitting .298/.399/.533 with 27 home runs and 102 RBIs while playing solid defense at shortstop. He finished ninth in the MVP voting (his teammate Mo Vaughn won). The AL All-Star shortstops were Ripken and Gary DiSarcina of the Angels.
For pitchers, the top five (or seven, with ties):
1. Bill Hands, 1969: 8.4
2. John Tudor, 1985: 8.1
3. Mike Caldwell, 1978: 8.1
4. Jim Abbott, 1991: 7.6
5. Mark Eichhorn, 1986: 7.4 (as a reliever!)
6. John Denny, 1983: 7.4
7. Dave Roberts, 1971: 7.4
Hands went 20-14 with a 2.49 ERA for the Cubs, pitching 300 innings. Don't blame him for the Cubs' fade that year: He had 2.27 ERA in August and 2.27 in September.
