Michael Jensen, left, shows off his championship award.

Michael Jensen wasn’t the leader after the first round, but the Los Altos native improved each round to come out on top at the Alameda Commuter Championship.

The St. Francis High graduate posted a 1-under, 70, for a total of 274 for four rounds (10 under). The tournament was held over the last two weekends of April at the Chuck Corica Golf Complex in Alameda.

Positioned in the top 10, two strokes behind the leader after the first round, Jensen posted a 3-under, 69 to put him in a five-way tie for the lead after Round 2. The UC Berkeley senior shot a 5-under 66 in the third round to take the lead, two strokes ahead of the nearest competitor.

Pursued by several players going into the final round, Jensen held them off – and stretched his lead to three strokes – to claim the championship.

Along with the championship trophy, Jensen received a Medalist trophy, awarded to the lowest score at the end of the first weekend of play.

His younger brother, Chris Jensen, tied for 15th at the tourney.
