Welcome to the Club, Lieber
Jon Lieber did something today that not a whole lot of pitchers can claim to have done. He gave up 4 home runs in a single inning. He started off the fateful second inning with back-to-back home runs by Adam Dunn and Joey Votto, but eventually settled in and got Edwin Encarnacion to pop-out.
Lieber surely breathed a sigh of relief, only to have Paul Bako hit a home run on the very next pitch. Three batters later Jerry Hairston Jr. hit the final home run of the inning, tying what I believe is a record for most home runs allowed by one pitcher in a single inning.
The last pitcher to do it was Chase Wright of the Yankees, who gave up four home runs in a row on April 22nd last season. Luckily for Wright, it was a nationally televised game against the Red Sox.

If I recall correctly, when Chase Wright did it he became just the second player to ever allow the four home runs. I just looked it up and apparently Paul Foytack, a Tigers pitcher from the 50s was the first.
