The outfielder from Lafayette, La., had only been in the Major Leagues since Friday after the Rays recalled him to take the place of John Jaso when he was placed on the 15-day disabled list.
Once the game got out of hand Wednesday night, Rays manager Kevin Cash began to substitute liberally. Mahtook was included in the substitutions as he took over for Kevin Kiermaier in center field in the bottom of the fifth. That meant an at-bat for Mahtook in the top half of the inning once Logan Forsythe reached on a two-out double.
