Burbank scored six runs in the first three innings, but if it thought the game was over Burbank sure had another thing coming. Pasadena’s Robert Lain needed only one pitch to hit a grand slam over the center field wall and the Bulldogs added four more in the sixth to cap a remarkable come-from-behind 9-7 win over Burbank on Tuesday afternoon in the Pacific League opener for both schools. William Yost started the two-out, five-run rally with a single to center. Andrew Phillips followed suit with another single to center and Chris Rucker’s RBI single brought home Yost to start the rally and make it 6-1. Chris Klein got hit by a pitch to load the bases, that’s when Lain came to the plate and, to say the least, made things interesting. Ivew Brown started the sixth with a single that rolled by the pitcher and took a bounce off the mound. He beat the throw to second. Phillips singled to right and Chris Rucker’s RBI single to right field scored Brown to make it 6-6. Klein loaded the bases again with a bunt that got past Burbank pitcher Chase Mersola. The throw to first was not in time. Lain, again facing a bases loaded situation, hit a sacrifice fly, scoring Phillips for the winning run. Kevin Winder put the icing on the cake with a single to right field, scoring Rucker and Klein for a 9-6 lead. Klein picked up his first win in two appearances. He walked and gave up a hit to the first two batters in the seventh, had two fielder’s choice for the first two outs, allowing Mersola to score and make it 9-7. Klein got Ryan Favor to ground out to second for the final out. Pasadena showed grit. It took longer than expected, but the bats finally came alive when confidence sunk in. Burbank pitcher Taylor McCauley perhaps played an inning too long. He had given up only two hits heading into the fifth. It wasn’t until midway through the sixth when McCauley was replaced.
