Shane Monahan had hits in his first two at-bats, including a two-run triple in the second.San Bernardino became the first team to score in double-digits against Lancaster this season, and did it by the third inning, hanging on to beat Lancaster 12-9 in front of 3,263 fans Thursday night.
The Stampede took a 10-3 lead after a six-run third, but watched the JetHawks score in each of the first seven innings.
"It's nice to see these guys battle back like that," JetHawks manager Dave Brundage said. "As we were coming back, I felt like we were going to win the ballgame."
Lancaster starter Ken Cloude came into the game with the eighth-best ERA in the California League (2.51), but the JetHawks' defense betrayed him. The defense committed two errors in the second and two more in the fourth that led to six unearned runs.
San Bernardino, 17-10 and a half-game behind Lancaster in the Cal League's Southern Division, also tagged Cloude for eight hits, including a two-run home run by Matt McCarty in the second.
That was the Stampede's fifth homer in the last two games against a Lancaster pitching staff that leads the Cal League in team ERA and is second in home runs allowed.
With an 18-10 record, the JetHawks also lead the league in runs scored, and they proved why Thursday night.
Lancaster scored one run in the first, fourth, fifth and sixth and seventh and twice in the second and third to slowly peck away at the lead.
Among the offensive highlights:
Shane Monahan had hits in his first two at-bats, including a two-run triple in the second.
After grounding out in the first, Marcus Sturdivant walked three times, tripled and scored twice in his next four at-bats.
In his return to the lineup after a four-game absence, Jose Cruz Jr. singled in the first and doubled and scored in the fourth.
But the JetHawks couldn't take full advantage of 10 walks by a parade of Stampede pitchers. When Jeff Paluk came in to start the bottom of the seventh, he was the fifth San Bernardino pitcher.
He walked the second batter he faced, Shawn Buhner, with a 10-8 lead.
When Carlos Villalobos singled past first baseman Ervan Wingate on the next pitch, Stampede manager Del Crandall's nightmare had come to pass: Jesus Marquez strode to the plate as the potential goahead run.
Marquez grounded out to drive in Buhner and make it 10-9.
That the JetHawks were on pace to tie the game in the eighth and win it in the ninth - this from a team that has "lived by the big inning" according to Brundage - proved that nothing was conventional about Thursday's game.
Lancaster also had another poor defensive outing - save for Mike Lanza's snare on Wingate's sharp grounder up the middle and flip to second baseman Jason Cook to start a double play in the seventh.
The JetHawks' four errors in the first eight innings gave them nine in their last three games.
Miscues by Marquez and Lanza in the third, coupled with five hits, all came after two were out in the third.
Kyle Cooney, Tito Landrum and Wingate had consecutive-singles off Cloude to begin the rally, and Cliff Anderson hit a two-run double to end it, giving the Stampede a 10-3 lead.
