Andy Pettitte struck out 10 batters in shutting out the Rays for 7.1 innings last night, improving his ERA to 2.78 in five starts since coming out of retirement.
And afterward the Yankees left-hander admitted to Bryan Hoch of MLB.com that even he’s surprised by how well he’s pitching at age 39:
Pettitte’s average fastball has lost some zip, going from 89 miles per hour before retirement to 87 miles per hour now, but his secondary numbers show that his first sub-3.00 ERA since 2005 isn’t merely a fluke. He’s inducing more ground balls than ever before and has a 32/7 K/BB ratio in 36 innings for his best strikeout rate since 2004 and the best strikeout-to-walk ratio of his 17-year career.
