Jake Rosenbeck got locked in early and never let up as he averaged 270 for his five games in the Sunday Rolloffs League at Medina Lanes.
The 33-year-old right-hander fired 258-258-300--816 in the qualifying round of singles handicap league and followed that up with a 534 two-game total in the rolloff portion to place first for the week in Division 1.
The perfect game is Rosenbeck's second USBC-certified 300 (his first came on Nov. 14, 2019) and the 800 series also is his second USBC-certified 800 (he had an 817 series in October 2018).

Veteran bowlers Jim Passarell and Mike Pettinella had 751 and 741, respectively, in leagues at Oak Orchard Bowl and Mancuso Bowling Center.
