Sims

Waiting patiently as he watched Ethan Schiefelbein, then Seth Hernandez perform as ace pitchers for Corona, junior left-hander Mason Sims has now assumed that role — and what a performance he turned in Monday during a Big VIII League game.

Sims struck out 12 with no walks in six innings of Corona’s 3-0 win over King. He gave up four hits. Anakin Tolman picked up the save in the seventh. Sims learned from the two current minor-league pitchers when he was a freshman and sophomore. He showed potential and is set to lead the Panthers’ pitching staff for the next two years.
