Sproat threw five scoreless innings for Double-A Binghamton on Friday, allowing only two hits and striking out 13 without walking a batter.
The 23-year-old put together the most dominant performance of his pro career to date, and Sproat struck out the final 11 batters he faced. As Ben Weinrib of MLB.com notes, the record for consecutive Ks in a single game at the major-league level is 10, a record shared by Aaron Nola, Corbin Burnes and Hall of Famer Tom Seaver. Sproat has struggled to maintain consistency as the weather has warmed up, but in general his first season at Double-A has been a rousing success as he's produced a 2.45 ERA, 0.87 WHIP and 77:15 K:BB through 62.1 innings. Most encouragingly, he's reduced his walk rate from 5.7 BB/9 last year at High-A to a 2.2 BB/9 with Binghamton.
