Rangers lefthander Kasey Kiker joined low Class A Clinton from extended spring camp in Surprise, Ariz., a little over a week ago and Midwest League hitters have yet to even sniff him.

Kiker, the 12th-overall pick in last year’s draft, struck out eight over five shutout innings in the Lumber Kings’ 3-2 win against Burlington on Saturday and is now 1-0, 0.00 with a 17-5 strikeout-walk ratio in 10 innings. The 19-year-old has allowed just five hits.

“His fastball’s been where it needs to be–anywhere from 89-94 (mph),” Rangers farm director Scott Servais said. “But it’s been his breaking ball and his changeup that have been most impressive. The development of his secondary pitches have improved tremendously.”
