Yesterday late in the game thread, a question arose about whether a player could have more than 3 assists in an inning. We concluded the answer was clearly Yes, because of the way the rule is constructed (you get credit for an assist even if a subsequent error results in no out being recorded). But I couldn't quickly locate any documented instances. Well, SABR colleagues to the rescue. Here are three such instances: 4 for second base Jason Kipnis CLE 6/22/2014 (5th inning) http://www.baseball-reference.com/boxes/CLE/CLE201406220.shtml 4 for third base Craig Grebeck White Sox, 5/2/1995 (5th inning); http://www.baseball-reference.com/boxes/TOR/TOR199505020.shtml 4 for shortstop Juan Uribe COL, 5/21 2002 (4th inning) http://www.baseball-reference.com/boxes/COL/COL200205210.shtml
