With a 35-20 record and an RPI of 25, Arizona is in good shape to make a regional this year.

Not many other teams on the West Coast are feeling that way.

With the regular season ending on Sunday and the field of 64 for the NCAA baseball tournament announced Monday, the West Coast has been tough to figure out this season.

Five teams are ranked by Collegiate Baseball in the top 25, but only four are in the top 40 in RPI, which is weighed heavily when picking at-large regional teams.

Hawaii coach Mike Trapasso, whose team dropped Cal State Fullerton 20 spots in the RPI by winning two of three against the Titans last weekend, thinks part of the problem is that the number of quality teams in the West region is on the rise.

“On the national scene the West Coast is looked at as having a down year, but in reality, we don’t have maybe the superstar teams on the top, but what we’ve seen on the West Coast is a microcosm of what we’re seeing in the Big West,” Trapasso said. “There’s more parity with some of the mid-teams and lower teams improving and upping their game and we’re all beating up on ourselves.”

Case in point are the Big West-leading Titans, who are in a de facto championship series this weekend against second-place Long Beach State.

The Big West is one of the only conferences, along with the Pac-12, not to hold a championship tournament, but the regular-season title comes down to this weekend’s series at Long Beach.

Fullerton was in position to host a regional as one of the top 16 teams in the country at this time last week.

Two losses to Hawaii have forced the Titans into a winner-take-all series against the Dirtbags.

A series loss to Long Beach would not only cost the Titans the Big West’s automatic berth, but put them on the bubble for an at-large selection. Fullerton’s currently 54th in the RPI rankings, falling 26 spots in a week.

The Big West only got two teams into regionals last year, but both Fullerton and UC Santa Barbara hosted.

“We were 12-12 last year and 12-12 this year, but to me the league is significantly better and stronger this year than it was last year — from top to bottom in particular,” Trapasso said. “I think it’s the same way on the West Coast and the East Coast bias is that the west is down, but it’s really not. The west is up, but maybe it’s just those top teams aren’t having the 45-win seasons because the teams they are playing are better.”

Hawaii is not in the at-large discussion for the fourth consecutive year and will once again finish with a losing overall record.

It’s likely UH will finish either four or five games out of first place in the Big West, which is especially tough considering Hawaii lost five one-run games in conference play and had an extra-innings loss to Long Beach State in which it had three different scoring opportunities to walk off with a win.

“I’d say we’ve got to be the best 23-27 team in the nation,” senior outfielder Matt LoCoco said. “Hindsight is 20-20 and you can always ask, ‘What if?’ but at the end your record is what it is.”

Hawaii can end the year with back-to-back series wins against ranked teams. Arizona is ranked No. 24 by Collegiate Baseball and finished 16-14 in Pac-12 play, which is currently good enough for fourth place.

The Wildcats are coached by Jay Johnson, who is in his first year with the Wildcats after spending two seasons as the head coach at Nevada.

“It’s a chance to win another series against a good team,” said shortstop Jacob Sheldon-Collins, who is one of 10 seniors playing their final series. “I will just try to take it as another game, but maybe that last game (Sunday) it will kick in that this is it. We’ll take it as it comes.”
