Many may not be able to stay awake for the end of this one, but the Orioles hold a 3-0 lead on Boston in the fifth inning.
Each team has had a mess of base runners and chances to score more runs than they have. For Boston, that's a goose egg so far versus Chris Tillman.
Boston has four hits and two walks against Tillman, but is 0-for-5 so far with runners in scoring position. Tillman has thrown 74 pitches so far.
The O's took a 2-0 lead in a messy top of the first for Daisuke Matsuzaka on an RBI double by Derrek Lee off the monster and Vlad Guerrero's RBI groundout.
Lee left the game in the third inning with a left oblique strain.
The Orioles added to the lead on another clutch hit by Matt Wieters when he delivered an RBI single in the third. Wieters is now 12-for-28 during a seven-game batting streak.
With a win the Orioles would improve to 3-1 against Boston on the year and get back to the .500 mark at 20-20. They were last at .500 on May 1st at 13-13.
Updated: The Orioles have added to their lead in the fifth on RBIs by Mark Reynolds and J.J. Hardy to make it 5-0.
