The softball doubleheader of the week takes place in the Intermountain Conference, while the Eastern Oregon League features a big twin bill as well.
Hermiston visits Redmond for two games that could have a huge impact on the IMC playoff race and the Pilot Rock Rockets visit Culver with first-place on the line in the EOL West division.
Hermiston at Redmond
The Bulldogs have had this weekend circled on the calendar for some time as two IMC heavyweights collide in Redmond.
Redmond welcomes the No. 8-ranked Hermiston Bulldogs at 2 p.m. Saturday. The Bulldogs (12-1, 4-0 IMC) take a nine-game winning streak on the road and Redmond is also undefeated in IMC play at 3-0.
Pendleton at Summit
The defending IMC champion Pendleton Buckaroos may have lost to rival Hermiston Tuesday, but it came after a 2-0 start to IMC play.
Pendleton (6-9, 2-1 IMC) visits Summit at 2 p.m. Saturday and the young Buckaroos have a chance to be right in the thick of things with a sweep.
Summit has posted a 1-3 IMC record thus far.
Baker at Mac-Hi
The Mac-Hi Pioneers are in a situation in that they need wins to stay with a strong Greater Oregon League.
The Pioneers (4-2, 2-2 GOL) have a chance at 2 p.m. Friday to shake things up in the GOL, if they can find a way to steal two from No. 4-ranked Baker Bulldogs at home.
"This is a really important series for us," Mac-Hi head coach Barry Weis said.
Baker (9-3, 5-1 GOL) lost to Elmira 1-0 in the Class 3A title game last season.
"We know we will have out work cut out for us," Weis said.
Unfortunately for the Pioneers, Sarah Truax is highly doubtful for the game because of a hamstring pull and Weis said they will have to lean on the arm of Ranzy York, who has thrown well thus far.
Vale at Riverside
The three-time GOL player of the year Erica Hancock has pitched strong of late and has propelled the Riverside Pirates to the top of the GOL standings.
The No. 10-ranked Pirates (9-5, 7-1 GOL) have reeled off six straight GOL wins since splitting with Baker and will host Vale (5-3, 3-1 GOL) at 1 p.m. Friday.
Pitching has been Riverside's strong suit, but the bats have come to life after scoring 22 runs against Ontario last Saturday
Culver at Pilot Rock
Some things never change and after a strong Eastern Oregon League season last year, the Pilot Rock Rockets are again playing strong in league.
The Rockets (8-2, 6-0 EOL) dispatched Echo/Stanfield twice Tuesday and host Culver at 1 p.m. Friday for a twin bill.
The victor of this series will make a major statement in the league and be in good position for the stretch run.
Culver struggled during pre-season play, but has played perfect at 5-0 in the EOL.
"We're looking forward to playng Culver," Rocket head coach Rick Hoisington said.
Culver has been the only league team to defeat Pilot Rock, each of the past two years.
Wahtonka at Umatilla
The young Umatilla Vikings come off a split with Heppner Tuesday and welcomes winless Wahtonka at 4 p.m. Friday for an EOL twin bill.
Umatilla (5-7, 1-4 EOL) stand in the middle of the pack in the EOL West Division standings and can ill-afford to drop a game to keep pace with the likes of Culver and Pilot Rock, who square off with each other this weekend. Wahtonka has an 0-6 EOL record.
Heppner at Echo/Stanfield
The Heppner Mustangs are looking for an EOL sweep at 1 p.m. Saturday, visiting Echo/Stanfield.
Heppner (1-5 EOL) split with Umatilla Tuesday and they catch Echo/Stanfield (4-2 EOL), who lost twice to Pilot Rock.
The Mustangs will have to deal with freshman Ashley Martinez, who has tossed three no-hitters this season and helped Echo/Stanfield win four games, one more than all of last season.
The TigerScots come off a split with Pine Eagle and have a full plate of games, starting today with an EOL doubleheader at Elgin.
"The weather may not hold for our game with Elgin, but we really feel like we need to win two," Weston-McEwen head coach Jeff Griggs said.
The TigerScots (6-4, 1-3 EOL) feel they let one get away against Pine Eagle, but hope to build momentum for an EOL doubleheader at 1 p.m. Saturday visiting Nyssa.
"We've made strides with our hitting, but it was our defense that slipped a little last week," said Griggs. "We have been a little short-handed, but this week we can play people where we want and it should play into our favor."
