Seattle's starters Tuesday, Chris Jakubauskas in the opener and Felix Hernandez in the nightcap, gave up a combined six hits and two runs.

Unfortunately for Jakubauskas, one of the two hits off him was a two-run double by Paul Konerko in the opener that cost him the win. However, he allowed just three runners in eight innings.

Hernandez, by contrast, was ahead 4-0 after two innings, and Chicago never solved him.

It's been a daily story for the Mariners, who have seen their starters compile a cumulative ERA of a 3.50 this season while posting 10 of Seattle's 13 wins.

A dozen times already the Mariners have seen their starting pitchers allow two runs or fewer, including in both ends of Tuesday's doubleheader.

And the rotation wasn't supposed to look like this. Brandon Morrow, who was supposed to be the No. 3 starter, is now the closer. Ryan Rowland-Smith, the No. 5 starter, is on the disabled list, making room for Jakubauskas.

WHITE SOX 2, MARINERS 1 (Game 1): Chris Jakubauskas pitched the best game of his brief big-league career, but he took the loss when all the damage against him came in one inning.

Jakubauskas retired the first 10 men he faced, then walked the 11th, Josh Fields. After a single by Carlos Quentin, Jakubauskas retired Jermaine Dye before Paul Konerko hit a double between third baseman Adrian Beltre and the third base line.

That was it for the White Sox, the final 13 of whom went down in order against Jakubauskas. However, the Mariners got just five hits of Bartolo Colon and the Chicago bullpen.

MARINERS 9, WHITE SOX 1 (Game 2): Felix Hernandez ran his record to 4-0 with eight shutout innings to salvage a doubleheader split for the Mariners.

Seattle seemed to hit at will behind Hernandez, pounding out 19 hits, including the first career five-hit game for Russell Branyan and the first career five-RBI game for Yuniesky Betancourt.
