One of the last team's to use MLB-approved gear, Cardinals used a keypad and small speaker (hidden in Hicks' hatband) to call pitches Tuesday in specific spots.
The club is 2-5 in Hicks' seven starts after he walks five in three innings Tuesday.
Former closer pitches into the fourth, but weight of four walks catches up to him. Cardinals walk eight, allow three homers, two by Jansen to split short series.
Helsley and his 0.00 ERA have yet to appear on back-to-back days, and that's by design. Also: Cardinals unpack their PitchCom tech to test-drive a new strategy.
He's hitting .340 and has started at five positions since being brought up from the minors and Marmol says Donovan is the emergency catcher, too.
