Oldham contributed six innings to Everett's 1-0 shutout over first-pace Salem-Keizer. The Aquasox dropped the Volcanoes into a first-place tie with Eugene, which won on Tuesday.
If the Mariners short-season-A team completes the three-game sweep today, it might result in a three-way tie atop the Northwest League West Division.
Oldham allowed only two base runners in his first win since moving into the rotation.
Oldham hasn't given up a run in his two starts and lowered his batting average against to .089.
The Mariners picked up the 21-year-old left-hander in the eighth round of the recent June draft.
For the second-straight game, first baseman Eric Blakeley scored the decisive run; this time on shortstop Osvaldo Navarro's single. Blakeley did it himself on Monday with a seventh-inning homer.
In another case of deja-vu, Brandon Moorhead saved his second game in as many nights and his league-leading seventh on the season.
Moorhead entered in the eighth with runners on first and third and proceeded to retire the final five batters in order.
Tacoma (AAA) 8, Portland 3: The Rainiers brought out the whoopin' stick against Portland with 16 hits and two homeruns.
Left-hander Craig Anderson gave up two runs over five innings for his sixth victory.
Brian Tollberg felt the brunt of the Rainiers offensive explosion, dropping his record to 3-2.
Julio Mosquera, moved from behind the plate over to third base, played flawless defense and hit his third homerun.
Pat Borders drove home two runs to increase his team-leading RBI total to 38, as he heads to the AAA-All Star Game next Wednesday.
El Paso 6, San Antonio (AA) 1: Kevin Olore (0-2) gave up five runs in four innings as the Missions' five-game win streak came to an end.
Olore ranks last on the Missions' pitching staff with a 5.67 ERA.
Inland Empire (Advanced-A) 4, High Desert 3: The 66ers scored one in the first and, more importantly, three in the last for their sixth win in eight games.
Ismael Castro tied the game in a peculiar fashion, reaching third on a passed ball and scoring on a balk.
California League All-Star Greg Jacobs ended the contest with this third hit of the game, driving in David Delucchi from second.
Jacobs leads the league with a .358 batting average, .601 slugging percentage, 33 doubles, and 48 extra-base hits.
Dayton 6, Wisconsin (A) 4: With the loss to Dayton, the Timber Rattlers have lost five-straight, furthering their descent into the cellar of the Midwest League Western Division.
The Rattlers have now dropped 10-straight at their home park.
The Rattlers scored the first three runs of the game, but Dragons first baseman Jason Vavao eclipsed that total in one swing with a grand slam in the fourth.
Dayton scored twice more in the fifth to put the game out of reach.
Rattlers starter Juan Sandoval picked up his team-leading eighth loss.
Third baseman Matt Hagen hit his 15th home run in the seventh.
Tacoma (40-53; -7.5): RH Brian Sweeney (7-7 W-L, 4.28 ERA) vs. Portland
Notes: Sweeney hasn't allowed more than two earned runs in his last five appearances, but he has a 1-2 record to show for it. Over his last 34 innings, he has a 1.85 ERA and 25 strikeouts.
San Antonio (14-6, second half; +4.0): LH Bobby Madritsch (7-4, 3.78) vs. Round Rock
Notes: The Texas League West Division leading Missions start a four-game series with the Round Rock Express, who are only four games back.
Inland Empire (11-7, second half; -1.5): LH Ryan Ketchner (9-3, 3.57) vs. High Desert
Notes: Ketchner pitches on the same day fellow nine-game winner Ervin Santana (Rancho Cucamonga, Anaheim Angels) takes the mound. Both drew rather weak competition for their 10th win…
The 66ers may have to deal without the services of closer Mike Steele, the California League leader with 16 saves, because of a lingering and troubling shoulder injury.
Wisconsin (6-14, second half; -6.5): RH T. A Fulmer (5-5, 2.90) vs. Dayton
Notes: Fulmer leads the Midwest League with four complete games this season. In his last two starts, Fulmer has received zero runs of offensive support in consecutive 1-0 losses to Clinton.
Only five times has the Wisconsin offense supplied Fulmer with more than four runs in his 17 starts.
Everett (11-10; -1.0): LH Victor Ramirez (2-2, 4.76) vs. Salem-Keizer
Notes: Everett, while only hitting .240 so far, still leads last place Tri-City by 48 points (.192).
