Jeff Karstens, in his second start for the Pirates, retires the first 23 batters he faces before Chris Young doubles in the 8th. Karstens settles for a two-hit shutout and has not allowed a run in his first 15 innings since being acquired by Pittsburgh. Karstens aids his own cause with his first two career hits, both off Randy Johnson.

The Mariners stun the Twins with a 10-run seventh inning, coming back from a 6-0 deficit in an eventual 11-6 victory at Safeco Field. With six runs driven in, Raul Ibanez, who hits a grand slam and a two-run single in the frame, establishes a club record for RBIs in one inning, one more than Ken Griffey Jr.’s mark set in 1999.

During a Brewers’ 6-3 loss to the Reds at Great American Ball Park, first baseman Prince Fielder confronts starting pitcher Manny Parra in the dugout, shoving the hurler twice after an angry exchange of words. The Milwaukee hurler had taken a no-hitter into the fifth, but gave up six runs on four hits and four walks before leaving the game for a pinch hitter in the seventh inning.

At the start of the rain delay during the Astros and Cubs game at Wrigley Field, fans are advised to take cover in the concourse due to a tornado warning being issued by the National Weather Service for downtown Chicago. The game resumes in 2 hours, 45 minutes, but approximately an hour later more thunder and lightning and another 39-minute stoppage cause the contest to be called in the bottom of the eighth, with Houston credited with a 2-0 rain-shortened victory.

Francisco Liriano, sent down to the minors after an 0-3 start in April attempting to come back from Tommy John surgery, blanks the Indians for six innings in his return to the Twins’ rotation. The right-hander’s performance propels Minnesota into first place in the American League Central with the eventual 6-2 victory over the Tribe along with a White Sox loss.

In the first game after the Manny Ramirez trade to the Dodgers, the Fenway Faithful enthusiastically welcome Jason Bay, the player replacing the Boston icon. The former Pirates outfielder doesn’t disappoint, tripling and scoring the winning run in the 12th inning of the Red Sox’s 2-1 victory over the A’s.
