Grand Slams: more.

WEDNESDAY, APRIL 27, 2011 Bases loaded home runs, aka, grand slams.

Players listed in the title link for this post include career leaders in bases loaded home runs and batters with at least 500 career home runs.  And Roger Maris.

At bats with bases loaded is still missing for Lou Gehrig and other old timers.  It exists for most seasons for Gil Hodges but I did not include his partial data.

Every player I looked at and for whom there were bases loaded at bats had better home run rates with the bases loaded than with the bases not loaded.

I also broke down Barry Bonds by season in a separate tab.

Robin Ventura hit home runs at a rate 2.35 times better when he batted with the bases loaded than when he batted when the bases were not loaded.  Here are the tops:

Robin Ventura 2.35
Carlos Lee 2.04
Eddie Murray 1.78

The batters second and third to Lou Gehrig's record 23 grand slams, Alex Rodriguez (22) 1.44 and Manny Ramirez (21), 1.27 times better.

Worst rate (HR/AB) difference between loaded and not loaded:

Barry Bonds .69

Frank Robinson .62

Jim Thome .56 (worst)

Dave Kingman has the best rate with the bases loaded: 8.8 (141 AB/ 16 HR).  Sexson, McCovey, McGwire, Rodriguez are next in that order, all better than one homer every 10 AB.

Mark McGwire has the best rate when the bases are not loaded: 9.85 (5,604 AB / 569 HR).  Barry Bonds, Jim Thome, Harmon Killebrew, Sammy Sosa, Rodriguez are next in that order, all better than one homer every 14 AB.

Remember, we do not have such data for Gehrig and the other old timers.
