X chart mystery

How does Cecil Cooper (1e6) allow a single with no one on and one out? Was he distracted by the red head sitting behind first base?

Actually, here it is. It would fall under rule 20.72

With Corners In, use these rules:
(20.71) Do not award a SINGLE** for a batter's card groundball followed by a "+". Treat the play as if the "+" did not appear.
(20.72) On a groundball hit to the first baseman, third baseman, follow the rules for Infield In (including changing X-Chart results followed by a "#" to read "SI2").
(20.73) On a groundball to the second baseman or shortstop, follow the rules for Infield Back.
(20.74) Rules 20.5 and 20.51 also apply.
(20.75) Any runner or combination of runners also may be held on base when the infield is positioned as Corners In.
(20.8) For gb()X results, refer to the Super Advanced Fielding Chart. Under each table for G1, G2 and G3 results, there are guidelines for each baserunning situation, with Infield "Normal" (back) and Infield In. There is also a Super Advanced Groundball Results Chart printed on the Fielding Chart that describes the outcome of each event that can occur on the Fielding Chart.

That makes sense Steve but the op said there was no one on and one out. That makes me ask why would the infield be in? With nobody on would infield not be playing standard defense, infield back?

That distracted by red head seems to have some credibility here.

Corners will often default in with an A or B bunter with speed at the plate (to defend against bunt for a base hit). Without even looking, I'll bet you a box of doughnuts VanSlyke is an A or B bunter and at least a 1-16 runner
