With one starter selected, Head Coach Marty Lees continues to mix and match the Cougar lineup as they get set to face No. 10 Oregon State at Bailey-Brayton Field on Thursday.

The Cougars (10-19, 3-9) have yet to find consistency through a three-game series under Lees, working with a majority of underclassmen. Freshman right-hander Parker McFadden (2-3) and freshman left-hander Ryley Widell (1-1) both saw action out of the bullpen against Arizona, another effort to find the best fit for his players.

“Still working with the starting rotation right now,” Lees said Tuesday during his weekly press conference. “Ian Hamilton we have tabbed to start this weekend. Right now [pitching] Coach [Dan] Spencer, myself and [hitting] Coach [Jim] Horner will take a look at the matchup and see who we can start and who we feel good about and play game by game, hitter by hitter.”

Hamilton (1-7) will start Friday for WSU with the Thursday and Saturday starters still to be determined. Both McFadden and Widell, in addition to freshman right-hander Ryan Ward (1-1), have taken to the mound, starting for the Cougars over the past three series.

While the Cougars have given up 48 runs over their last two conferences series’ against Arizona State and Arizona, sophomore right-handed relief pitcher Colby Nealy (0-1) has seen improvements from the younger pitchers.

“The young guys are definitely improving which is good going into this series,” Nealy said Tuesday. “They know what Pac-12 baseball is like and like our coaches always say, they’re not freshmen anymore. They’ve pitched, they’ve got experience, so like you said they got their feet wet. I can see that they’re a lot more confident on the mound, but there’s still some room to grow.”

At the plate, the Cougars have only managed 22 runs over the same six-game stretch, winning just two games. Redshirt junior second baseman Trek Stemp currently leads the team with a .356 batting average and .408 on-base percentage.

However, Stemp said while being patient and seeing pitches helps some players, it never hurts to swing away. For a team that has walked 88 times while striking out 237, it’s just about having Stemp pass on the confidence in others to swing away.

“It’s good to walk because you’re on base,” Stemp said Tuesday. “But if you swing you got a chance to hit a double or an extra base-hit so then you’re in scoring position right away. Hitters know it – just learning what type of hitter you are.”

First pitch for WSU and OSU is set for 7:05 p.m. on Thursday while Friday will start at 4:05 p.m. Both games will be televised on the Pac-12 Network. First pitch for Saturday is scheduled for Noon. Live Stats will be provided on WSUCougars.com and on Twitter @Cougbaseball for all three games.
