"The guys are starting to catch some momentum," said Upper Dublin coach Ed Wall, whose squad improved to 4-1 overall and 3-0 in conference action. "They're feeling good about themselves."
The 6-foot-5, 185-pound Jacobson, a four-year varsity member ticketed for Rhode Island, mixed a fastball clocked in the mid-80-m.p.h. range, curveball, slider, and change-up. He threw 113 pitches, with 73 for strikes.
"He's really starting to be the pitcher we had hoped he would be," Wall said. "His determination has been a big part of that. He's going out there with a mind-set that he can't be beat."
Against Upper Moreland, Jacobson mostly quieted a feared hitting lineup that features the Hooker brothers, Charlie and Colton; Mike Cavanaugh; and Pat Driscoll.
"He's one of the better pitchers in the league," said Charlie Hooker, a senior outfielder-pitcher bound for Alderson Broaddus. "He was hitting his spots well, getting ahead in the count, and keeping us off balance."
Aided by a hit batsman and dropped infield pop-up, the Cardinals took a 2-0 lead in the third. The Golden Bears (3-2, 2-2) evened things in the fourth on a steal of home and Colton Hooker's RBI single.
For the hosts in the sixth, Harrison Guber started with a single and Jacobson drew a walk. After starter Eddie Decker was replaced by Charlie Hooker, pinch-hitter Conor McFadden set the stage for Nealis' winner with a perfectly placed bunt.
In suffering the loss, Decker, a senior righthander who last season went 7-0 with a 0.87 ERA, fanned nine and yielded four singles.
Did Jacobson, with his size, consider also playing basketball for the school?
"That's actually my worst sport," he said. "I'm just awkward on the court."
