Numbers generally don’t lie in baseball. And Zac Houston’s numbers are telling us this: He’s got strikeout stuff. Houston, the former Mississippi State star from Poplarville, fanned the side in an Arizona Fall League game on Monday, giving him four punchouts in two innings of scoreless relief for Mesa. The 6-foot-5, 250-pound right-hander, an 11th-round pick by Detroit in 2016, reached high-A ball this season. He had an 0.77 ERA and 20 strikeouts in 11 2/3 innings for Lakeland. Over 87 2/3 innings as a pro, Houston has 140 strikeouts, or 14.4 per nine innings. That’s strikeout stuff. He throws an upper 90s fastball and a quality slider. His walk totals are a bit high (4.6 per nine) but probably not a major concern at this point. Houston turns 23 next month. Baseball America ranked him as the Tigers’ No. 23 prospect entering 2017; MLB Pipeline doesn’t currently have him in the top 30. That should change.
