Houck does not have a big repertoire although the splitter was an excellent addition. He threw 50 strikes in 89 pitches, 56%, compared to the preferred 67%, and benefitted from 2 GIDP's. I think Cora pulled him at the right time.
This was Whitlock's 3d appearance in 8 Sox games--with a total of 107 pitches compared to Eovaldi's 177, Houck's 167, and Pivetta's 135. He has pitched 8.2 innings to Eovaldi's 10, Houck's 9, and Pivetta's 7.2. Whitlock has thrown no more than 39 pitches in an outing.
