If you aren’t yet, get used to seeing that “TBA” — as in To Be Announced — for the University of Hawaii baseball team’s probable starting pitcher in the third game of Big West Conference series.

But there’s a big difference from recent years. UH is now dealing from a position of strength, not desperation, as it doesn’t reveal its cards regarding who it will send to the mound.

Coach Mike Trapasso has four very effective starting pitchers to choose from for three-game sets when league play begins at Cal Poly on Friday.

“I think what we’ll do is go into each series with a TBA. We have trust in both guys,” Trapasso said.

When he says “both guys,” he’s talking about Jackson Rees and Neil Uskali. One will now be the odd man out each week, but it will strengthen the bullpen.

Uskali scattered seven hits in as many innings, while striking out seven and walking none in the Rainbows’ 3-2 win over Nevada on Sunday. UH completed its preconference slate by taking three of four games from the Wolf Pack.

In Saturday’s 7-2 loss, Rees allowed just one earned run in seven innings, but the Hawaii bullpen and defense collapsed in the last two stanzas.

Brendan Hornung — the staff ace — is the only of the four starters to not deliver a quality outing this week. But the ’Bows won despite his allowing of 10 hits and all the Nevada runs in seven innings of UH’s 12-5 win to start the series Thursday.

On Friday, Dominic DeMiero went seven solid and Hawaii rallied with two runs in the eighth for a 3-2 win.

In the four games against Nevada, UH starters totaled just two walks in 28 innings.

“No walks again today,” Trapasso said.

Check this out: Hornung (3-2, 2.52 ERA), DeMiero (4-1, 1.82), Rees (3-0, 3.14) and Uskali (4-1, 3.00). You have to go way back to find a more consistent quartet of Rainbows starting pitchers.

They’re a big reason Hawaii is now 18-9. With the 24-game Big West season left to play, the ’Bows are just five victories away from matching last year’s 23 wins. They’ve already surpassed by two the victory total of 2013, the year that started the ongoing four seasons in a row of under .500 in winning percentage.

Of course the goals now are much loftier, but Hawaii needs just eight Big West victories to finish with more wins than losses overall for the first time since it joined the conference after the 2012 season.

It was four years ago when the Rainbows started having so many injury problems on the mound that the entire starting rotation had to be revised, sometimes weekly. It was also around then that most of UH’s prized recruits passed up college in bunches to go pro.

Trapasso still has concerns about pitchers’ health (what baseball coach doesn’t?); Patrick Martin might be out for the season, and he was being counted on as the staff’s best lefty. But Dylan Thomas has been poetry in motion lately, establishing himself as UH’s closer despite a nagging back injury earlier in the season.

Rees (88-92 mph) throws harder than Uskali. But when Uskali has command of his fastball, slider and change-up, he’s very hard to hit. He lost his change-up for a brief spell Sunday, but got it back.

“It’s tough,” Uskali said. “It disappears randomly sometimes. Every pitcher hopes that doesn’t happen. I even hit a guy, which I almost never do. But the next inning I warmed up with (the change-up) two more times than I usually do, and I got the command back.”

Picking which pitcher will start in each series is one of those good problems.

“It’s something we haven’t had in a little while. Depth. And it’s guys who are pounding the zone,” Trapasso said. “We’ll see how they match up against the various opponents. Jackson might be a guy for a team that can be stopped by velo (velocity).”

The offense has improved this year, and that includes speed and power. But Trapasso felt UH underachieved offensively most of this series.

“Frankly, we weren’t very good in three of the four games. We should have had at least four (runs in the first inning, instead of one),” he said.

Josh Rojas — who also jumped to snare a scorched liner at third to end the game — was the exception. In the third inning, he hit a ball that banged off the sweet spot of the right-center wall, allowing him to motor into third for a triple and his second run-scoring hit of the game.

They’ve won eight of their last nine and 14 of their last 18. But now the real thing starts.

Will this Rainbows baseball season be a successful one?

They’re off to a great start. But the answer to that question — like who will be the mound starter for the rubber games of Big West series — is still TBA.
