I was in Rancho Cucamonga for the opener of a four-game series between the San Jose Giants and the Quakes. Jordan Johnson took the mound for his seventh start of the season, and wasn't his sharpest, but showed off his fastball/curveball combination that makes him a top-20 prospect in the organization. The pitches produced eight swinging strikes in six innings, certainly not his highest total of the season, but Johnson managed to work around 11 baserunners and only allow one run. The contact was hard at times off Johnson, who surrendered eight hits, including three extra-base hits. Johnson entered the night with opposing hitters averaging .198 off him in 2016.
The fastball was a 90-93 mph offering that had slight tail when he threw it with a two-seam grip. It was mostly the four-seam though, placing it well on the outside edge against right-handers and getting swing-throughs on high heat. His tight 12-6 curveball looked great all night, serving as an out pitch and a get-it-in-there strike. It ran anywhere from 78 to 81 during the evening. He also threw a firm changeup that ran a bit higher than usual, in the 86-89 range. It wasn't a noteworthy pitch on Friday, but it's known to have splitter-type depth and could be a plus pitch in the near future.
In Johnson's highlights above, pay special attention to the three-pitch strikeout (FB, CB, FB) starting at the 2:29 mark. Probably his best sequencing of the night, but certainly not the only good curveball. The clip is packed full of good hammer.
