Suddenly, the Pacific League is heating up.

A lot of that has to do with the fact the Arcadia High School baseball team is suddenly on a three-game losing streak after Burbank snapped the Apaches’ 41-game league winning streak last week.

Pasadena (12-10, 7-6) then handed Arcadia (18-8, 10-3) its second consecutive loss with a 5-2 victory, giving Bulldogs coach Mike Parisi his first-ever win over his alma mater.

Also intensifying the league race was Pasadena’s 5-4 win over Crescenta Valley (19-7, 11-2) on Monday after trailing 4-0 nearly the entire game.

Then came Tuesday, the biggest news another Arcadia loss, this time to Burroughs, 4-2. Pasadena beat Glendale, 6-3, while Crescenta Valley beat Muir, 12-0, to clinch at least a share of the league title. Burbank (13-8, 10-3) also beat Hoover and is now tied for second with Arcadia while Burroughs (11-13, 8-5) is third, ahead of Pasadena.

Those latest results have sent the league standings into havoc, meaning final placements might not take shape until Friday, and even that could be a stretch depending on the scenario.

Pasadena seems to be reaping the benefits thus far. It appeared as if the Bulldogs would not make the CIF-Southern Section playoffs halfway through the season, but they’ve suddenly positioned themselves with all but a guarantee to make the postseason when pairings are released next week.

The Bulldogs have one game remaining, scheduled for Friday against Muir (6-17, 1-11). Parisi has been unsuccessful in getting Muir to change Friday’s game time or move it to Thursday since several players are scheduled to also take AP tests Friday.

Regardless of when the game is played and its outcome, Pasadena will more than likely earn an at-large berth thanks to its winning record.

But if Pasadena wins, it can end up tied for fourth with Burroughs if Burbank beats Burroughs on Friday.

If that happens, Pasadena and Burroughs would forgo the first tiebreaker (head-to-head) because the teams split the series this year, sending them to a 10 a.m. playoff game Saturday to decide who will finish where in the final standings.

Arcadia visits Crescenta Valley on Friday night. A Falcons win would give them an outright league title while sending the Apaches spiraling down to third place if Burbank beats Burroughs as well. Arcadia can clinch a share of the league title with a win.
