I wouldn't be in too much despair, there are several players that can pinch hit at anytime. It should also be noted that Goins is hitting above average (wRC+ of 116) since July 3rd (189 plate appearances - http://www.fangraphs.com/statsd.aspx?playerid=9807&position=2B/SS&type=&gds=2015-07-03&gde=2015-09-23&season= ) when he changed his hitting style (both stance and plate discipline). Pillar had a good series against the Yankees when it was needed. I think Pillar will be a multi-year All Star in the future once he consistently shows the plate discipline that he did during the Yankee series. Pennington has had some clutch hits as a Blue Jay and I think Barney was 1 for 2 a couple of nights ago against the Yankees (Barney isn't crappy, he was a past Gold Glove winner).
Let's see how many runs are driven in by, and scored by the 6, 7, 8 and 9 hitters tonight. And also, how well Pillar, Barney, Pennington and Goins do on defense; a run saved is just as important as a run scored.
