James was the first catcher selected by the Rays out of Oklahoma, where he led the Sooners with a .330 batting average this season as a junior. He has started at five different positions, but is primarily a catcher or first baseman.
Franco, from Florida International, posted a 1.09 ERA this season as a senior, the second-best mark in Division I, and struck out 112 batters. The 22-year-old right-hander spent his first two seasons at Howard Junior College in Texas and underwent Tommy John surgery in 2012.
Miles, a senior from Tennessee Tech, hit .380 this season with 17 doubles, 11 home runs and 54 RBIs in 58 games on his way to being named a first-team Louisville Slugger All-American third baseman.
Pike posted a 1.89 ERA and struck out 125 hitters in 90 2/3 innings during his senior season at Oklahoma City University. Pike threw a perfect game on March 7 against St. Gregory's in an NAIA Sooner Athletic Conference game, striking out 18 batters. He followed it up with a no-hitter a week later.
The four signings represent four of the eight players the Rays selected on Day 2 of the Draft.
