This weekend’s farewell celebration might not be limited to the University of Hawaii baseball team’s senior class.

This also might be the final collegiate homestand for three juniors — catcher Kekai Rios, starting pitcher Jackson Rees and shortstop Maaki Yamazaki — and third-year sophomore closer Dylan Thomas. NCAA Division I players who have been in college at least three years are eligible for selection in next month’s Major League Baseball Draft.

“That’s the thing about baseball,” UH coach Mike Trapasso said. “You celebrate your seniors but you lose a lot of good juniors sometimes because of the draft. It’s one of those weekends where we have a lot of guys who will be or could be playing their last games in front of the home crowd.”

On Friday night, the Rainbow Warriors open a three-game series against Long Beach State at Les Murakami Stadium. The ’Bows close the regular season with next week’s road series against UC Santa Barbara.

“We don’t try to talk our juniors out of signing,” Trapasso said. “We tell them the truth on whether we think they’re ready and whether this is the best opportunity for them.”

Rios and Rees have drawn the most attention from pro scouts. If they are drafted, Trapasso said, their option of returning to UH next season can be used in negotiations.

“This is the year they’ll have the bargaining power,” Trapasso said of Rios and Rees. “After this year, when they’re seniors, they won’t. It depends on where they’re drafted and if it’s best for them from a development standpoint to sign.”

Rios is hitting .305 overall, and .406 against Big West opponents. Rees is 4-2 with a 3.59 earned-run average.

“I’m trying to enjoy this time here and trust the process and see how it all pans out,” Rios said. “I haven’t been thinking too much about (the draft). I’m focused on winning some games.”

Trapasso said he encourages any junior who is drafted to ask for the club to pay for the remaining classes needed to graduate.

“I feel it’s a win-win for me if I get taken in the draft or if I come back,” Rios said. “This isn’t a bad spot to play.”

Rees earned a bachelor’s degree on Saturday, but did not participate in the commencement ceremony because the ’Bows were on the road.

Yamazaki, who grew up in Tokyo, has intrigued scouts because of his defense and team-high .323 average. Yamazaki indicated he would consider pursuing a pro career if he were picked in the first 30 rounds of the 40-round draft.

“If I don’t get drafted (high), I want to come back (for) one more year,” Yamazaki said. “I want to get bigger and stronger and work hard to get better.”

Thomas is in a unique position. He has the numbers — 13 saves, 1.30 ERA and 0.69 WHIP — and time. He is draft eligible as a third-year player, but he also will be only a junior next season.

“Dylan is in a different situation because of his redshirt year (in 2016),” Trapasso said. “Next year, he’ll be just like this year, a junior, so he’ll have that bargaining power. A lot with Dylan is where he will be drafted and the money for that slot.”

For now, Thomas is scheduled to pitch in the prestigious Cape Cod Baseball League this summer. Thomas, who has excelled with a darting slider, said he wants to improve his fastball and develop another out pitch.

“I’ll have to weigh my options when they happen,” Thomas said. “I’m hoping for the best (in the draft), obviously, but I’m definitely happy to come back next year and compete here.”
