This Henry Owens guy was the 34th overall pick for the Sox in 2011 out of HS and was showing up as high as Top-20 on the pre-season prospect reports last winter. Tonight will be his 5th ever ML start. Got hit hard by the Mariners in one game but has been decent to good in the other three. John Sickels posted this about Owens upon his call-up in early August: In 2014 he posted a combined 2.94 ERA in 159 innings divided between Double-A Portland and Triple-A Pawtucket with a 170/59 K/BB. He has spent all of 2015 with Pawtucket, producing a 3.16 ERA in 122 innings with a 103/56 K/BB and just 84 hits allowed. He has been particularly sharp recently, with a 34/8 K/BB in 32 innings over five July starts with a 2.84 ERA. Owens is a 6-6, 220 pound southpaw born July 21, 1992. His arsenal consists of a fastball in the 88-92 range, peaking at 93-94 when he pushes for extra velocity. The fastball works well even at the lower velocity notches because he mixes it efficiently with an above-average change-up and a decent breaking ball. Although he occasionally struggles with his command, his feel for pitching is considered quite strong in general. He's shown he can adjust and make positive changes when things aren't going well. Joe Kelly (Saturday's starter) came from the Cardinals in the Lackey deal and, in typical StL fashion, Lackey got better while the younger Kelly regressed. He's 7-6 but with a 5+ ERA and faces deGrom Wade Miley (Sunday) we've seen in his Arizona days. He's 0-1 in 3 career starts vs NYM. Syndergaard goes for the Mets.
