Worth noting

• Entering Tuesday's doubleheader, the Pirates were 13-13 against five current division leaders: Detroit (3-1), St. Louis (4-2), Oakland (1-2), Atlanta (3-4) and the Dodgers (2-4).

• Left-hander Francisco Liriano is the first Pittsburgh pitcher with at least 11 wins in his first 15 starts with the club since Earl Hamilton, who did it in 1918-19.

Liriano's 2.16 ERA would rank him fourth in the National League -- if he'd pitched enough innings to qualify. That's a pretty remarkable commentary on the efficiency of the pitcher who did not make his first start until May 11. The only four NL pitchers with more wins have worked an average of 50 more innings.
