On June 11th, the Dominican Republic native tossed three-hit ball over 6.0 shutout innings against the New York Yankees as the A's went on to defeat the Bronx Bombers, 6-4, in Oakland. Colon, who is currently one out shy of 2,500.0 career innings, struck out three in the 102-pitch outing. The 16-year veteran continued his winning ways on June 16th, allowing two runs on eight hits with three strikeouts in 7.0 innings as Oakland topped the visiting Seattle Mariners, 10-2. After battling a 35-pitch second inning in which Seattle tallied a pair of runs, the right-hander settled down to retire 12 straight batters and 16-of-17 on just 52 pitches over the next five innings in the win. On June 21st in Seattle, the two-time All-Star allowed three runs on seven hits with four strikeouts in 8.0 innings as the Athletics doubled up the Mariners, 6-3.
Colon improved to 17-12 with a 3.92 ERA in 34 career starts against Seattle, the most victories among active pitchers against the M's.
The triumph also marked his 10th win at Seattle's Safeco Field, the most among visiting pitchers. In his final start of the month on June 28th, Bartolo allowed one run on six hits with five strikeouts over 8.0 innings to lead Oakland to a 6-1 victory over the St. Louis Cardinals at O.co Coliseum.

Colon also had eight straight winning decisions with a pair of no-decisions over a 10-start span from July 21-September 10, 2005 with the Angels.
