Arizona Diamondbacks
Texas Rangers
Miami Marlins
Toronto Blue Jays
Tampa Bay Rays

The turf the Rangers, D-Backs and Marlins will be playing on is called B1K, and it is produced by Georgia-based Shaw Sports Turf. Though it is synthetic, the teams believe the imitation grass mimics the real thing in terms of how it plays and affects the bodies of players.
“We didn’t want the best turf surface in Major League Baseball, we wanted the best playing surface in Major League Baseball,” Rangers executive VP for business operations Rob Matwick told The Wall Street Journal. “People might say baseball should be played on grass. I’d say it should be played on the best quality surface we could put our players on.”
