Don't look now, but Tyler Duffey is pitching very well in Rochester.
He's pitched eight innings so far, all in relief, in three games, and he's done something that's a bit odd: He has a 2-1 record with NO EARNED RUNS allowed. (He's allowed two unearned runs.)
He's struck out 10 in 8 innings, and has issued no walks and only 2 hits (That's a 0.25 WHIP rate).
At this rate, He might get called up, especially if Hildenberger continues to falter.
